AB  - The spectrum, intensity, and overlap of symptoms between functional gastrointestinal
disorders (FGIDs) and other gastrointestinal disorders characterize patients with FGIDs, who are
incredibly different in their backgrounds. An additional challenge with regard to the diagnosis
of FGID and the applicability of a given treatment is the ongoing expansion of the risk factors
believed to be connected to these disorders. Many cytokines and inflammatory cells have been
found to cause the continuous existence of a low level of inflammation, which is thought to be a
basic pathophysiological process. The idea of the gut–brain axis has been created to offer a basic
framework for the complex interactions that occur between the nervous system and the intestinal
functions, including the involvement of gut bacteria. In this review paper, we intend to promote the
hypothesis that FGIDs should be seen through the perspective of the network of the neuroendocrine,
immunological, metabolic, and microbiome pathways. This hypothesis arises from an increased
understanding of chronic inflammation as a systemic disorder, that is omnipresent in chronic health
conditions. A better understanding of inflammation’s role in the pathogenesis of FGIDs can be
achieved by clustering markers of inflammation with data indicating symptoms, comorbidities,
and psycho-social factors. Finding subclasses among related entities of FGIDs may reduce patient
heterogeneity and help clarify the pathophysiology of this disease to allow for better treatment.

AB  - This study aimed to explore how hybrid varieties impact broiler
chickens' production and slaughter performance. We applied standard rearing
techniques over a 42-day period. The trial involved a total of 420 broiler chickens
of the following hybrids: Cobb 500 and Ross 308. Weekly performance tests were
conducted, assessing average daily gain, feed consumption, feed conversion rate,
mortality, and European Poultry Efficiency Factor. After controlling for final
body weights on the 42nd day, a random sample of 12 broilers per genotype, with
an equal gender distribution, was selected for slaughter parameter analysis.
Following slaughter traits were determined: pre-slaughter weight of chickens,
slaughter yield, share of abdominal fat, chicken thigh circumference, and chest
angle. The results revealed no significant difference in food consumption between
the examined hybrids. Chickens of the Cobb 500 genotype exhibited significantly
higher (p<0.01) gain and a more favorable feed conversion rate. Due to its better
vitality, feed conversion rate, and gain, Cobb 500 chickens demonstrated
significantly higher (p<0.01) European Poultry Efficiency Factor values. In
contrast, Ross 308 chickens displayed statistically significantly lower (p<0.05)
slaughter yield and chest angle values. At the same time, the proportion of
abdominal fat and chicken thigh circumference showed no significant difference
between the tested hybrids.

AB  - The aim of the study was to evaluate the effect of three protein
levels (with or without protease enzymes) on the weight and percentage yield of
each meat class in two genotypes of broiler chickens (fast-growing hybrid Cobb
500 and medium-growing hybrid Master Gris). Each genotype was divided into a
control group (C group) fed with a commercial feed mixture and an experimental
group fed with a low protein diet of 4% (E-I group) or 6% (E-II group) in relation
to the control group, with the addition of 200 mg/kg Ronozyme ProAct (E-I
group) or 300mg/kg Ronozyme ProAct (E-II group).
Weight and percentage yield of the meat classes were influenced by the
genotype. The fast-growing hybrid Cobb 500 had higher masses of all meat
classes and a higher percentage of class I meat, while the percentage of class II
and III meat was lower than in the medium-growing hybrid Master Gris (P<0.05).
Feeding had no effect on the weight and percentage yield of the individual meat
classes in either hybrid (P>0.05).

the food industry, especially in creating functional products and assessing its impact on public health.
Inulin, a versatile carbohydrate compound, not only acts as a fat replacer but also serves as a dietary
fiber source, enhancing the overall nutritional value of the foods. Furthermore, inulin’s fermentation
by beneficial gut bacteria results in the production of short-chain fatty acids, contributing to colorectal
cancer prevention and glycemic control, catering to the evolving preferences of health-conscious
consumers.

AB  - Due to the high demand for low-fat, healthier meat products, alternative strategies are pursued to
reduce fat content while maintaining the fundamental properties of traditional products. The research
strives to obtain products with reduced fat content and caloric value with the addition of inulin. Four
groups of cooked chicken sausages were tested: the control group without fat replacement, the second
with 50%, the third with 75%, and the fourth with 100% fat replacement with inulin suspension.
Sausages with a higher inulin content had a significantly (p<0.05) higher process loss and cooking
loss than the sausages from the control group. The first and second groups had significantly (p<0.05)
better emulsion stability. Reducing the fat content in sausages significantly affected (p<0.05) some
sausages characteristics, such as moisture, L*(lightness), a* (redness), and b* (yellowness). As a result,
the caloric value of sausages with inulin was significantly (p<0.01) impacted throughout all groups.
In summary, the study demonstrates that incorporating inulin as a prebiotic dietary fiber enables the
production of cooked sausages with reduced fat content and optimal physico-chemical properties. This
innovative meat product not only offers lowered energy value but also holds exceptional nutritional
value, representing a significant source of calories derived from reduced fat content supplemented with
prebiotic fibers (inulin).

Household spending trends reveal a notable shift, marking an increase since 2016. The study explores meat products' affordability and nutrient density, challenging conventional assumptions. Mortadella emerges as the most nutrient-dense despite its lower calorie content due to high protein content, while pâté commands a higher market price despite its lower nutrient quality.

AB  - Tanini su, kao velika grupa heterogenih jedinjenja različitog biološkog porekla, široko rasprostranjeni u biljnom svetu. Zbog svoje heterogenosti, tanini ispoljavaju različite efekte u ishrani preživara. Cilj ove doktorske disertacije je bio ispitivanje upotrebe preparata kestenovih tanina u obroku tovne jagnjadi, kako bi se ispitao njihov uticaj na fiziološke i proizvodne pokazatelje. 
	Ispitivanja su obavljena kroz dva, metodološki različita ogleda. U oba ogleda je uključeno po 30 jagnjadi MIS rase, neposredno nakon završenog perioda odbijanja od majki. Prosečna telesna masa jagnjadi u ogledu 1 je iznosila 20,55 kg, dok je u ogledu 2 iznosila 20,50 kg. U ogledu 1 je korišćen standardni farmski obrok za ishranu odlučene jagnjadi, dok su u ogledu 2 formulisani obroci tako da zadovolje potrebe u metaboličkom proteinu (MP) za prirast od 250 g/dan, dok je neto energije za porast (NEmeat) bilo više za oko 14%, što odgovara prirastu od oko 275 g/dan. Na taj način, su u ogledu 2 korišćena tri obroka uz pretpostavku da će uticaj tanina dovesti do zadovoljenja potreba za prirast veći od 250 g/dan. 
	Kao izvor tanina korišćen je preparat kestenovih tanina, komercijalnog naziva Farmatan®. U ogledu 1 formirane su tri grupe, sa po 10 jagnjadi, na osnovu sadržaja Farmatan®-a u suvoj materiji (SM) obroka: K (kontrola, bez dodatih tanina); T1 (9,46 g preparata/kg SM obroka) i T2 (18,87 g preparata/kg SM obroka). U ogledu 2, na osnovu sadržaja preparata u obroku, formirane su sledeće grupe: KON (kontrola, bez dodatih tanina); 10T (20,17 g preparata/kg SM obroka) i 20T (40,33 g preparata/ kg SM obroka). Oba ogleda su postavljena kao jednofaktorski ogledi sa po tri tretmana, gde su analizom varijanse testirane razlike između njih, a značajnost razlika između srednjih vrednosti određene na osnovu testa najmanjih razlika (LSD test). Oba ogleda su trajala 60 dana (ne računajući adaptacioni period), tokom kojih je dnevno praćeno konzumiranje SM. Na svakih 15 (u ogledu 1), odnosno 10 dana (u ogledu 2) praćene su promene u telesnoj masi jagnjadi, kako bi se odredili dnevni i ukupni prirasti, kao i parametri iskoristivosti hrane (konverzija, Klajberov odnos - KR, kao i efikasnost proteina - EP i efikasnost energije - EEN). Kako bi se utvrdilo da li tanini mogu uticati na promene vrednosti biohemijskih parametara krvi, u ogledu 1 jagnjadima je uzorkovana krv prvog i poslednjeg dana ogleda, nakon čega su odrađene analize. Određivanje prividne svarljivosti u oba ogleda je utvrđena indirektnom metodom korišćenjem pepela nerastvorljivog u hlorovodoničnoj kiselini kao indikatora, kroz tri kolekciona perioda u oba ogleda. U ogledu 1 kolekcioni periodi su trajali 5 dana, i to od 15. do 19. dana (I period); od 30. do 34. dana (II period) i od 45. do 49. dana ogleda (III period). U ogledu 2, kolekcioni periodi su trajali 6 dana, a obavljani su u periodu od 14. do 19. dana (I period), od 29. do 34. dana (II period) i od 44. do 49. dana (III period). Prividna svarljivost je određena za sledeće parametre: SM, organska materija (OM), SP, sirove masti (SMa), sirova celuloza (SC), deterdžentska vlakna (nerastvorljiva u neutralnom - NDF, odnosno kiselom deterdžentu - ADF), bezazotne ekstraktivne materije (BEM) i nestrukturni ugljeni hidrati (NFC). Po završetku hranidbenog dela ogleda, sva jagnjad su žrtvovana kako bi se ispitale klanične osobine, hemijski i masnokiselinski sastav mesa. Kao dodatni efekat, izvršena je i analiza ekonomske održivosti korišćenja preparata kestenovih tanina u obroku u oba ogleda. Ova analiza je obuhvatila troškove ishrane na osnovu dana (THd), troškove ishrane na osnovu prirasta (THp), neto profit (NP) i ekonomsku isplativost (EKI) korišćenja ovog izvora tanina. 
	Konzumiranje SM u ogledu 1 je bilo identično kod K i T2 (1,20 kg SM/dan) i veće od T1 (1,13 kg SM/dan), što se pre svega objašnjava slabijim konzumiranjem kabaste komponente obroka (sena) kod ove grupe. Postavka i sprovođenje ogleda 2 je omogućilo konzumiranje slične količine SM kod sve tri grupe, te je prosečno iznosilo 0,97 kg SM, 0,99 kg SM i 1,00 kg SM dnevno za KON, 10T i 20T, redom. Iako se usled adstringentnog ukusa tanina moglo očekivati da će doći do smanjenog konzumiranja, u ispitivanim količinama, kestenovi tanini nisu uticali na ovu pojavu. Razlike u konzumiranju se objašnjavaju kumulativnim efektom promenljivih parametara mikroklime, povremenom izlaganju blagom uznemiravanju, a u ogledu 2 i promenama obroka i hijerarhijskim odnosima u grupi. Iako je poređenje ova dva ogleda moguće sprovesti samo do određene mere, primećuje se da je u ogledu 1 konzumiranje bilo veće u toku celog perioda trajanja ogleda. Takođe, u ogledu 1 je konzumiranje bilo veće nego što korišćeni holandski normativi (CVB, 2018) preporučuju, i gotovo bez ograničenja, dok je u ogledu 2 količina date hrane određivana svakodnevno, na osnovu grupe koja je najslabije konzumirala prethodnog dana. 
	Na bolju iskoristivost hrane ukazuju veći prirasti pri istom nivou konzumiranja, čime se sugeriše povoljan uticaj kestenovih tanina. Posledično, najbolje konverzije SM, zatim najveće vrednosti KR, EP i EEN u ogledu 1 su ostvarila grla iz grupe T2 (4,46 kg SM/kg prirasta, 0,0181, 1,03 i 27,95), dok su najnepovoljniji parametri bili kod K (5,28, 0,0159, 0,83 i 23,26, redom). U ogledu 2, parametri su podeljeni po polovima, te su konverzije kod muških grla povoljnije kod taninskih (4,50 i 4,33 kg SM/kg prirasta redom za 10T i 20T) nego kod kontrolne (5,05 kg SM/kg prirasta). Uz ovo, kod muških životinja, taninske grupe (10T i 20T, redom) imaju veću vrednost KR (0,0155 i 0,0157), EP (1,47 i 1,60) i EEN (33,15 i 34,79) nego kod kontrolne grupe, kod koje su KR, EP i EEN redom iznosile 0,0137; 1,19 i 26,58). Sličan trend je primećen i kod ženskih grla, te je najbolja konverzija utvrđena kod 10T grupe (4,53), a najlošija kod KON (5,55).
	Dalje, u ogledu 1, najveće prosečne dnevne i ukupne priraste su ostvarila grla iz T2 grupe (270,37 g/dan i 16,22 kg), najmanje grla iz K (222,92 g/dan i 13,37 kg) uz primetnu značajnost razlika (p < 0,05). Grla iz T1 su ostvarila priraste od 259,26 g/dan, odnosno 15,55 kg, ali poređenjem sa ostale dve grupe značajnost nije utvrđena (p > 0,05). Slično, u ogledu 2, najveće prosečne dnevne i životne priraste su ostvarila grla iz 20T grupe (230,00 g/dan i 13,80 kg za muška, odnosno 220,00 g/dan i 13,20 kg za ženska grla), koji su značajno veći (p < 0,05) od prirasta postignutih kod KON (191,67 g/dan i 11,50 kg za muška, odnosno 174,17 g/dan i 10,45 kg za ženska grla), dok se ostvareni rezultati kod 10T nisu značajno razlikovali od prethodno dve navedene grupe. Na osnovu rezultata o prirastima za ceo period ogleda, u oba sprovedena ogleda, može se tvrditi da kestenovi tanini u obroku utiču na povećane priraste kod jagnjadi u tovu. Ukoliko se posmatra ceo period ogleda 2 (od 1. do 60. dana), eksperimentalne grupe su ostvarile veće priraste od jagnjadi iz grupa koje nisu dobijale tanine, što može ukazivati na to da kestenovi tanini utiču na poboljšano korišćenje proteina.
	Prividna svarljivost SM i OM u ogledu 2 je u prvom kolekcionom periodu (od 14. do 19. dana ogleda) bila, iako slična, nešto veća kod KON (84,02% i 85,23%) nego kod 10T (83,87% i 85,41%) i 20T (80,69% i 82,09%). Svarljivost SP je pratila sličan trend (78,44%, 78,42% i 69,04% za KON, 10T i 20T, redom), dok je svarljivost SMa rasla sa porastom tanina u obroku (83,53%, 89,15% i 90,44%). Trendovi vezani za svarljivost SMa se nastavljaju i u naredne dve kolekcije, što može značiti da su kestenovi tanini uticali na bolje iskorišćavanje masti usled promena u procesima buražne fermentacije. Zaključke vezane za svarljivost SP nije jednostavno doneti zbog eventualnog uticaja tanina na povećanje dotoka SP u tanko crevo. Drugim rečima, usled povećanog dotoka SP dolazi i do povećanja njegovog sadržaja u fecesu, što nužno ne znači njegovu lošiju iskoristivost. U prilog ovome govori i činjenica da su jagnjadi iz taninskih grupa ostvarila veće priraste od onih iz kontrolne.
	Ispitivanjem osnovnih parametara krvi u ogledu 1, nisu utvrđeni negativni uticaji kestenovih tanina na jagnjad u tovu.
	Iako se u literaturnim navodima uviđa da tanini mogu imati različit uticaj na hemijski sastav i masnokiselinski profil mesa, ovi efekti nisu utvrđeni u okviru disertacije, budući da u oba ogleda nisu utvrđene statističke značajnosti razlika ovih parametara među grupama.
	Analiza ekonomske održivosti je pokazala da je vrednost EKI u oba ogleda opadala sa dodavanjem kestenovih tanina u obroke, te  je prosečna vrednost ovog parametra iznosila 1,47, 1,29 i 0,98 u ogledu 1 za K, T1 i T2, redom. 
	U zavisnosti od obroka i pola, vrednost EKI se kretala kod KON 1,30-2,50, kod 10T 0,74-1,56, i kod 20T 0,54-1,06. Ovo ukazuje da kestenovi tanini utiču na smanjenje ekonomske efikasnosti u proizvodnji jagnjadi za tov. Ipak, pored cene preparata, na ovaj parametar utiče i paritet cena, koji je trenutno nepovoljan uz skupa hraniva i nisku cenu žive mere. Kestenovi tanini su uticali na poboljšanje konverzije i veće priraste jagnjadi, što ukazuje na bolju iskoristivost hrane, što je svakako prednost, naročito u velikim farmskim sistemima. Uz činjenicu da troškovi ishrane u stočarstvu čine najveći deo ukupnih troškova proizvodnje, u velikim sistemima, svaki dan skraćenja tova, kao i ušteda svakog kilograma obroka predstavlja veliku stavku u postizanju ekonomski efikasne proizvodnje, te kestenovi tanini predstavljaju potencijalno korisni dodatak u proizvodnji jagnjećeg mesa. Drugim rečima, upotrebu kestenovih tanina u tovu jagnjadi je moguće opravdati u takvim uslovima tržišta koji podrazumevaju jeftiniju proizvodnju hrane i povećanje tržišne cene žive mere jagnjadi.
	Prikazani rezultati ukazuju da korišćenjem kestenovih tanina kao aditiva u obrocima jagnjadi u tovu može doći do poboljšanja produktivnih parametara životinja, bez štetnih uticaja. U ispitivanim količinama, kestenovi tanini nisu uticali na pojavu smanjenog konzumiranja hrane, koja se eventualno mogla očekivati usled njihovog adstringentnog ukusa. Takođe, njihovom ingestijom tanini nisu ispoljili štetne uticaje na organizam životinja. Korišćenjem kestenovih tanina došlo je do poboljšanja iskoristivosti hrane, što je rezultiralo većim prirastima i nižim konverzijama u poređenju sa grupama koje nisu konzumirale dodate tanine, što je pre svega posledica boljeg korišćenja proteina. Analizom ekonomske održivosti je utvrđeno da, uz trenutni paritet cena, dodavanje kestenovih tanina u obroku može dovesti do finansijskog opterećenja proizvodnje, te ovo inicijalno deluje kao skupa opcija. Ali, ukoliko bi se postigla jeftinija proizvodnja hrane, uz povećanje tržišne cene jagnjadi, njihova upotreba se može opravdati. Smanjenje troškova proizvodnje se pre svega može ostvariti na velikim farmama, te se potencijal upotrebe kestenovih tanina pre svega u takvim sistemima može iskoristiti
AB  - Tannins, as a large group of heterogeneous compounds of different biological origins, are widely distributed in the plant world. Due to their heterogeneity, tannins exhibit various effects in the ruminant nutrition. The aim of this doctoral dissertation was to investigate the use of chestnut tannin product in the diet of fattening lambs to examine its impact on physiological and production indicators.
	The research was conducted through two methodologically different experiments. Both experiments included 30 lambs of the MIS breed, immediately after weaning from their mothers. The average body weight of lambs in experiment 1 was 20.55 kg, while in experiment 2, it was 20.50 kg. In experiment 1, a standard farm diet was used for the feeding of the selected lambs, while in experiment 2, diets were formulated to meet the metabolic protein (MP) requirements for a gain of 250 g/day, with net energy for gain (NEmeat) being about 14% higher, equivalent to a gain of about 275 g/day. Thus, in experiment 2, three diets were used assuming that the influence of tannins would lead to meeting gain requirements greater than 250 g/day.
	Chestnut tannin product, commercially known as Farmatan®, was used as the source of tannins. In experiment 1, three groups were formed, each consisting of 10 lambs, based on the Farmatan® content in the dry matter (SM) of the diet: K (control, no added tannins); T1 (9.46 g of product/kg of SM diet) and T2 (18.87 g of product/kg of DM diet). In experiment 2, groups were formed based on the following content of the product in the diet: KON (control, no added tannins); 10T (20.17 g of product/kg of SM diet) and 20T (40.33 g of product/kg of SM diet). Both experiments were set up as single-factor designs with three treatments, and differences between them were tested by analysis of variance, with the significance of differences between means determined by the least significant difference (LSD) test. Both experiments lasted for 60 days (excluding the adaptation period), during which daily SM intake was monitored. Changes in lamb body weight were recorded every 15 days (experiment 1) or 10 days (experiment 2) to determine daily and total gains, as well as feed utilization parameters (conversion, Kleiber ratio - KR, protein efficiency - EP, and energy efficiency - EEN).
	To investigate whether tannins could influence changes in blood biochemical parameters, blood samples were collected from the lambs in experiment 1 on the first and last days of the experiment, followed by analysis. Apparent digestibility in both experiments was determined using an indirect method with ash insoluble in hydrochloric acid as an indicator during three collection periods in both experiments. In experiment 1, collection periods lasted for 5 days: from day 15 to 19 (Period I), day 30 to 34 (Period II), and day 45 to 49 (Period III). In experiment 2, collection periods lasted for 6 days, and they were conducted from day 14 to 19 (Period I), day 29 to 34 (Period II), and day 44 to 49 (Period III). Apparent digestibility was determined for the following parameters: SM, organic matter (OM), CP, crude fat (SMa), crude fiber (SC), detergent fiber (neutral detergent fiber - NDF and acid detergent fiber - ADF), non-nitrogenous extractives (BEM) and non-fiber carbohydrates (NFC). At the end of the experiments, all lambs were slaughtered to examine the slaughter traits, chemical composition, and fatty acid profile of the meat.
	As an additional effect, an analysis of the economic sustainability of using chestnut tannins in the diet in both experiments was conducted. This analysis included feed costs per day (THd), feed costs per gain (THp), net profit (NP), and economic efficiency (EKI) based on the use of this tannin source.
	In experiment 1, intake of SM was identical in K and T2 (1.20 kg SM/day) and higher than in T1 (1.13 kg SM/day), primarily explained by lower intake of roughage in this group (hay). The setup and execution of experiment 2 allowed for similar SM intake in all three groups, averaging 0.97 kg DM, 0.99 kg DM, and 1.00 kg DM per day for KON, 10T, and 20T, respectively. Although it could have been expected that the astringent taste of tannins would lead to reduced intake, in the tested amounts, chestnut tannins did not affect this phenomenon. Differences in consumption are explained by the cumulative effect of variable microclimate parameters, occasional exposure to mild stress, and in experiment 2, changes in the diet and hierarchical relationships within the group. While the comparison of these two experiments can only be made to a limited extent, it is noticeable that consumption was higher throughout the duration of experiment 1. In addition, in experiment 1, consumption was higher than the Dutch standards (CVB, 2018) recommended, and almost without limitations, while in experiment 2, the amount of feed given was determined daily based on the group that consumed the least the previous day.
	Better feed efficiency is indicated by higher gains at the same level of consumption, suggesting a favorable effect of chestnut tannins. Consequently, the best SM conversion, followed by the highest KR, EP, and EEN values in experiment 1 were achieved by the T2 group (4.46 kg SM/kg gain, 0.0181, 1.03, and 27.95, respectively), while the least favorable parameters were observed in the K group (5.28, 0.0159, 0.83, and 23.26, respectively). In experiment 2, parameters were divided by gender, and feed efficiency was more favorable in male lambs in the tannin groups (10T and 20T, respectively) compared to the control (KON), with SM conversions of 4.50 and 4.33 kg DM/kg gain for 10T and 20T, respectively, while control had 5.05 kg SM/kg gain. Furthermore, in male animals, the tannin groups (10T and 20T) had higher KR values (0.0155 and 0.0157), EP values (1.47 and 1.60), and EEN values (33.15 and 34.79) than the control group, which had KR, EP, and EEN values of 0.0137, 1.19, and 26.58, respectively. A similar trend was observed in female lambs, with the best conversion in the 10T group (4.53) and the worst in the KON group (5.55).
	In experiment 1, the highest average daily and total gains were achieved by the T2 group (270.37 g/day and 16.23 kg), and the lowest by the K group (222.92 g/day and 13.37 kg), with significant differences (p < 0.05). The T1 group achieved gains of 259.26 g/day and 15.55 kg, but there were no significant differences compared to the other two groups (p > 0.05). Similarly, in experiment 2, the highest average daily and lifetime gains were achieved by the 20T group (230.00 g/day and 13.80 kg for males, 220.00 g/day and 13.20 kg for females), which were significantly higher (p < 0.05) than the gains achieved by KON (191.67 g/day and 11.50 kg for males, 174.17 g/day and 10.45 kg for females), while the results for 10T were not significantly different from the other two groups. Based on the gain results for the entire experimental period, in both experiments, it can be stated that chestnut tannins in the diet have a positive effect on lamb growth during fattening. If the entire experimental period of experiment 2 (from day 1 to day 60) is considered, the experimental groups achieved higher gains compared to the groups that did not receive tannins, indicating that chestnut tannins improve protein utilization.
	In experiment 2, apparent digestibility of SM and OM in the first collection period (from day 14 to 19) was slightly higher in KON (84.02% and 85.23%) compared to 10T (83.87% and 85.41%) and 20T (80.69% and 82.09%). CP digestibility followed a similar trend (78.44%, 78.42%, and 69.04% for KON, 10T, and 20T, respectively), while CF digestibility increased with the addition of tannins in the diet (83.53%, 89.15%, and 90.44%). Trends related to CF digestibility continued in the next two collection periods, indicating that chestnut tannins influenced better fat utilization due to changes in ruminal fermentation processes. Conclusions regarding CP digestibility are not straightforward due to the potential effect of tannins on increased flow of CP into the small intestine. In other words, increased CP flow also leads to an increase in its content in feces, which does not necessarily imply poorer utilization. This is supported by the fact that lambs in the tannin groups achieved higher gains than those in the control group.
	In experiment 1, an examination of basic blood parameters did not reveal any negative effects of chestnut tannins on fattening lambs.
	Although literature indicates that tannins can have different effects on the chemical composition and fatty acid profile of meat, these effects were not observed in this dissertation, as there were no statistically significant differences in these parameters among the groups in both experiments.
	The economic analysis showed that the economic efficiency index (EKI) in both experiments decreased with the addition of chestnut tannins to the diets, with average values of this parameter being 1.47, 1.29, and 0.98 in experiment 1 for K, T1, and T2, respectively. Depending on the diet and gender, EKI values ranged from 1.30 to 2.50 for KON, 0.74 to 1.56 for 10T, and 0.54 to 1.06 for 20T. This indicates that chestnut tannins reduce economic efficiency in lamb production. However, besides the cost of the used tannin product, this parameter depends on the parity of prices, which is currently unfavorable due to expensive feed and low live lamb prices. Chestnut tannins improved feed conversion and increased lamb gains, indicating better feed utilization, which is an advantage, especially in large farm systems. Considering that feed costs in livestock production constitute the largest part of total production costs, in large systems, each day of shortened fattening and every kilogram of saved feed represent significant cost savings, making chestnut tannins a potentially valuable addition to lamb production. In other words, the use of chestnut tannins in lamb fattening can be justified under such market conditions which includes cheaper feed production and higher market prices for live lambs. Cost reduction can primarily be achieved in large farms, so the potential use of chestnut tannins is particularly relevant in such systems.
	The presented results indicate that the use of chestnut tannins as additives in lamb diets can lead to improved production parameters without harmful effects. In the tested quantities, chestnut tannins did not affect reduced food consumption, which could have been expected due to their astringent taste. Additionally, their ingestion did not show harmful effects on the animals. The use of chestnut tannins improved feed utilization, resulting in higher gains and lower conversions compared to groups that did not consume tannins, primarily due to better protein utilization. The economic analysis found that, with the current price parity, adding chestnut tannins to the diet can lead to a financial burden in production, making it initially seem like an expensive option. However, if cheaper feed production and higher market prices for live lambs are achieved, their use can be justified. Reduction in production costs can be primarily realized in large farms, so the potential use of chestnut tannins is most suitable for such systems.

abstract = "Tanini su, kao velika grupa heterogenih jedinjenja različitog biološkog porekla, široko rasprostranjeni u biljnom svetu. Zbog svoje heterogenosti, tanini ispoljavaju različite efekte u ishrani preživara. Cilj ove doktorske disertacije je bio ispitivanje upotrebe preparata kestenovih tanina u obroku tovne jagnjadi, kako bi se ispitao njihov uticaj na fiziološke i proizvodne pokazatelje. 
	Ispitivanja su obavljena kroz dva, metodološki različita ogleda. U oba ogleda je uključeno po 30 jagnjadi MIS rase, neposredno nakon završenog perioda odbijanja od majki. Prosečna telesna masa jagnjadi u ogledu 1 je iznosila 20,55 kg, dok je u ogledu 2 iznosila 20,50 kg. U ogledu 1 je korišćen standardni farmski obrok za ishranu odlučene jagnjadi, dok su u ogledu 2 formulisani obroci tako da zadovolje potrebe u metaboličkom proteinu (MP) za prirast od 250 g/dan, dok je neto energije za porast (NEmeat) bilo više za oko 14%, što odgovara prirastu od oko 275 g/dan. Na taj način, su u ogledu 2 korišćena tri obroka uz pretpostavku da će uticaj tanina dovesti do zadovoljenja potreba za prirast veći od 250 g/dan. 
	Kao izvor tanina korišćen je preparat kestenovih tanina, komercijalnog naziva Farmatan®. U ogledu 1 formirane su tri grupe, sa po 10 jagnjadi, na osnovu sadržaja Farmatan®-a u suvoj materiji (SM) obroka: K (kontrola, bez dodatih tanina); T1 (9,46 g preparata/kg SM obroka) i T2 (18,87 g preparata/kg SM obroka). U ogledu 2, na osnovu sadržaja preparata u obroku, formirane su sledeće grupe: KON (kontrola, bez dodatih tanina); 10T (20,17 g preparata/kg SM obroka) i 20T (40,33 g preparata/ kg SM obroka). Oba ogleda su postavljena kao jednofaktorski ogledi sa po tri tretmana, gde su analizom varijanse testirane razlike između njih, a značajnost razlika između srednjih vrednosti određene na osnovu testa najmanjih razlika (LSD test). Oba ogleda su trajala 60 dana (ne računajući adaptacioni period), tokom kojih je dnevno praćeno konzumiranje SM. Na svakih 15 (u ogledu 1), odnosno 10 dana (u ogledu 2) praćene su promene u telesnoj masi jagnjadi, kako bi se odredili dnevni i ukupni prirasti, kao i parametri iskoristivosti hrane (konverzija, Klajberov odnos - KR, kao i efikasnost proteina - EP i efikasnost energije - EEN). Kako bi se utvrdilo da li tanini mogu uticati na promene vrednosti biohemijskih parametara krvi, u ogledu 1 jagnjadima je uzorkovana krv prvog i poslednjeg dana ogleda, nakon čega su odrađene analize. Određivanje prividne svarljivosti u oba ogleda je utvrđena indirektnom metodom korišćenjem pepela nerastvorljivog u hlorovodoničnoj kiselini kao indikatora, kroz tri kolekciona perioda u oba ogleda. U ogledu 1 kolekcioni periodi su trajali 5 dana, i to od 15. do 19. dana (I period); od 30. do 34. dana (II period) i od 45. do 49. dana ogleda (III period). U ogledu 2, kolekcioni periodi su trajali 6 dana, a obavljani su u periodu od 14. do 19. dana (I period), od 29. do 34. dana (II period) i od 44. do 49. dana (III period). Prividna svarljivost je određena za sledeće parametre: SM, organska materija (OM), SP, sirove masti (SMa), sirova celuloza (SC), deterdžentska vlakna (nerastvorljiva u neutralnom - NDF, odnosno kiselom deterdžentu - ADF), bezazotne ekstraktivne materije (BEM) i nestrukturni ugljeni hidrati (NFC). Po završetku hranidbenog dela ogleda, sva jagnjad su žrtvovana kako bi se ispitale klanične osobine, hemijski i masnokiselinski sastav mesa. Kao dodatni efekat, izvršena je i analiza ekonomske održivosti korišćenja preparata kestenovih tanina u obroku u oba ogleda. Ova analiza je obuhvatila troškove ishrane na osnovu dana (THd), troškove ishrane na osnovu prirasta (THp), neto profit (NP) i ekonomsku isplativost (EKI) korišćenja ovog izvora tanina. 
	Konzumiranje SM u ogledu 1 je bilo identično kod K i T2 (1,20 kg SM/dan) i veće od T1 (1,13 kg SM/dan), što se pre svega objašnjava slabijim konzumiranjem kabaste komponente obroka (sena) kod ove grupe. Postavka i sprovođenje ogleda 2 je omogućilo konzumiranje slične količine SM kod sve tri grupe, te je prosečno iznosilo 0,97 kg SM, 0,99 kg SM i 1,00 kg SM dnevno za KON, 10T i 20T, redom. Iako se usled adstringentnog ukusa tanina moglo očekivati da će doći do smanjenog konzumiranja, u ispitivanim količinama, kestenovi tanini nisu uticali na ovu pojavu. Razlike u konzumiranju se objašnjavaju kumulativnim efektom promenljivih parametara mikroklime, povremenom izlaganju blagom uznemiravanju, a u ogledu 2 i promenama obroka i hijerarhijskim odnosima u grupi. Iako je poređenje ova dva ogleda moguće sprovesti samo do određene mere, primećuje se da je u ogledu 1 konzumiranje bilo veće u toku celog perioda trajanja ogleda. Takođe, u ogledu 1 je konzumiranje bilo veće nego što korišćeni holandski normativi (CVB, 2018) preporučuju, i gotovo bez ograničenja, dok je u ogledu 2 količina date hrane određivana svakodnevno, na osnovu grupe koja je najslabije konzumirala prethodnog dana. 
	Na bolju iskoristivost hrane ukazuju veći prirasti pri istom nivou konzumiranja, čime se sugeriše povoljan uticaj kestenovih tanina. Posledično, najbolje konverzije SM, zatim najveće vrednosti KR, EP i EEN u ogledu 1 su ostvarila grla iz grupe T2 (4,46 kg SM/kg prirasta, 0,0181, 1,03 i 27,95), dok su najnepovoljniji parametri bili kod K (5,28, 0,0159, 0,83 i 23,26, redom). U ogledu 2, parametri su podeljeni po polovima, te su konverzije kod muških grla povoljnije kod taninskih (4,50 i 4,33 kg SM/kg prirasta redom za 10T i 20T) nego kod kontrolne (5,05 kg SM/kg prirasta). Uz ovo, kod muških životinja, taninske grupe (10T i 20T, redom) imaju veću vrednost KR (0,0155 i 0,0157), EP (1,47 i 1,60) i EEN (33,15 i 34,79) nego kod kontrolne grupe, kod koje su KR, EP i EEN redom iznosile 0,0137; 1,19 i 26,58). Sličan trend je primećen i kod ženskih grla, te je najbolja konverzija utvrđena kod 10T grupe (4,53), a najlošija kod KON (5,55).
	Dalje, u ogledu 1, najveće prosečne dnevne i ukupne priraste su ostvarila grla iz T2 grupe (270,37 g/dan i 16,22 kg), najmanje grla iz K (222,92 g/dan i 13,37 kg) uz primetnu značajnost razlika (p < 0,05). Grla iz T1 su ostvarila priraste od 259,26 g/dan, odnosno 15,55 kg, ali poređenjem sa ostale dve grupe značajnost nije utvrđena (p > 0,05). Slično, u ogledu 2, najveće prosečne dnevne i životne priraste su ostvarila grla iz 20T grupe (230,00 g/dan i 13,80 kg za muška, odnosno 220,00 g/dan i 13,20 kg za ženska grla), koji su značajno veći (p < 0,05) od prirasta postignutih kod KON (191,67 g/dan i 11,50 kg za muška, odnosno 174,17 g/dan i 10,45 kg za ženska grla), dok se ostvareni rezultati kod 10T nisu značajno razlikovali od prethodno dve navedene grupe. Na osnovu rezultata o prirastima za ceo period ogleda, u oba sprovedena ogleda, može se tvrditi da kestenovi tanini u obroku utiču na povećane priraste kod jagnjadi u tovu. Ukoliko se posmatra ceo period ogleda 2 (od 1. do 60. dana), eksperimentalne grupe su ostvarile veće priraste od jagnjadi iz grupa koje nisu dobijale tanine, što može ukazivati na to da kestenovi tanini utiču na poboljšano korišćenje proteina.
	Prividna svarljivost SM i OM u ogledu 2 je u prvom kolekcionom periodu (od 14. do 19. dana ogleda) bila, iako slična, nešto veća kod KON (84,02% i 85,23%) nego kod 10T (83,87% i 85,41%) i 20T (80,69% i 82,09%). Svarljivost SP je pratila sličan trend (78,44%, 78,42% i 69,04% za KON, 10T i 20T, redom), dok je svarljivost SMa rasla sa porastom tanina u obroku (83,53%, 89,15% i 90,44%). Trendovi vezani za svarljivost SMa se nastavljaju i u naredne dve kolekcije, što može značiti da su kestenovi tanini uticali na bolje iskorišćavanje masti usled promena u procesima buražne fermentacije. Zaključke vezane za svarljivost SP nije jednostavno doneti zbog eventualnog uticaja tanina na povećanje dotoka SP u tanko crevo. Drugim rečima, usled povećanog dotoka SP dolazi i do povećanja njegovog sadržaja u fecesu, što nužno ne znači njegovu lošiju iskoristivost. U prilog ovome govori i činjenica da su jagnjadi iz taninskih grupa ostvarila veće priraste od onih iz kontrolne.
	Ispitivanjem osnovnih parametara krvi u ogledu 1, nisu utvrđeni negativni uticaji kestenovih tanina na jagnjad u tovu.
	Iako se u literaturnim navodima uviđa da tanini mogu imati različit uticaj na hemijski sastav i masnokiselinski profil mesa, ovi efekti nisu utvrđeni u okviru disertacije, budući da u oba ogleda nisu utvrđene statističke značajnosti razlika ovih parametara među grupama.
	Analiza ekonomske održivosti je pokazala da je vrednost EKI u oba ogleda opadala sa dodavanjem kestenovih tanina u obroke, te  je prosečna vrednost ovog parametra iznosila 1,47, 1,29 i 0,98 u ogledu 1 za K, T1 i T2, redom. 
	U zavisnosti od obroka i pola, vrednost EKI se kretala kod KON 1,30-2,50, kod 10T 0,74-1,56, i kod 20T 0,54-1,06. Ovo ukazuje da kestenovi tanini utiču na smanjenje ekonomske efikasnosti u proizvodnji jagnjadi za tov. Ipak, pored cene preparata, na ovaj parametar utiče i paritet cena, koji je trenutno nepovoljan uz skupa hraniva i nisku cenu žive mere. Kestenovi tanini su uticali na poboljšanje konverzije i veće priraste jagnjadi, što ukazuje na bolju iskoristivost hrane, što je svakako prednost, naročito u velikim farmskim sistemima. Uz činjenicu da troškovi ishrane u stočarstvu čine najveći deo ukupnih troškova proizvodnje, u velikim sistemima, svaki dan skraćenja tova, kao i ušteda svakog kilograma obroka predstavlja veliku stavku u postizanju ekonomski efikasne proizvodnje, te kestenovi tanini predstavljaju potencijalno korisni dodatak u proizvodnji jagnjećeg mesa. Drugim rečima, upotrebu kestenovih tanina u tovu jagnjadi je moguće opravdati u takvim uslovima tržišta koji podrazumevaju jeftiniju proizvodnju hrane i povećanje tržišne cene žive mere jagnjadi.
	Prikazani rezultati ukazuju da korišćenjem kestenovih tanina kao aditiva u obrocima jagnjadi u tovu može doći do poboljšanja produktivnih parametara životinja, bez štetnih uticaja. U ispitivanim količinama, kestenovi tanini nisu uticali na pojavu smanjenog konzumiranja hrane, koja se eventualno mogla očekivati usled njihovog adstringentnog ukusa. Takođe, njihovom ingestijom tanini nisu ispoljili štetne uticaje na organizam životinja. Korišćenjem kestenovih tanina došlo je do poboljšanja iskoristivosti hrane, što je rezultiralo većim prirastima i nižim konverzijama u poređenju sa grupama koje nisu konzumirale dodate tanine, što je pre svega posledica boljeg korišćenja proteina. Analizom ekonomske održivosti je utvrđeno da, uz trenutni paritet cena, dodavanje kestenovih tanina u obroku može dovesti do finansijskog opterećenja proizvodnje, te ovo inicijalno deluje kao skupa opcija. Ali, ukoliko bi se postigla jeftinija proizvodnja hrane, uz povećanje tržišne cene jagnjadi, njihova upotreba se može opravdati. Smanjenje troškova proizvodnje se pre svega može ostvariti na velikim farmama, te se potencijal upotrebe kestenovih tanina pre svega u takvim sistemima može iskoristiti, Tannins, as a large group of heterogeneous compounds of different biological origins, are widely distributed in the plant world. Due to their heterogeneity, tannins exhibit various effects in the ruminant nutrition. The aim of this doctoral dissertation was to investigate the use of chestnut tannin product in the diet of fattening lambs to examine its impact on physiological and production indicators.
	The research was conducted through two methodologically different experiments. Both experiments included 30 lambs of the MIS breed, immediately after weaning from their mothers. The average body weight of lambs in experiment 1 was 20.55 kg, while in experiment 2, it was 20.50 kg. In experiment 1, a standard farm diet was used for the feeding of the selected lambs, while in experiment 2, diets were formulated to meet the metabolic protein (MP) requirements for a gain of 250 g/day, with net energy for gain (NEmeat) being about 14% higher, equivalent to a gain of about 275 g/day. Thus, in experiment 2, three diets were used assuming that the influence of tannins would lead to meeting gain requirements greater than 250 g/day.
	Chestnut tannin product, commercially known as Farmatan®, was used as the source of tannins. In experiment 1, three groups were formed, each consisting of 10 lambs, based on the Farmatan® content in the dry matter (SM) of the diet: K (control, no added tannins); T1 (9.46 g of product/kg of SM diet) and T2 (18.87 g of product/kg of DM diet). In experiment 2, groups were formed based on the following content of the product in the diet: KON (control, no added tannins); 10T (20.17 g of product/kg of SM diet) and 20T (40.33 g of product/kg of SM diet). Both experiments were set up as single-factor designs with three treatments, and differences between them were tested by analysis of variance, with the significance of differences between means determined by the least significant difference (LSD) test. Both experiments lasted for 60 days (excluding the adaptation period), during which daily SM intake was monitored. Changes in lamb body weight were recorded every 15 days (experiment 1) or 10 days (experiment 2) to determine daily and total gains, as well as feed utilization parameters (conversion, Kleiber ratio - KR, protein efficiency - EP, and energy efficiency - EEN).
	To investigate whether tannins could influence changes in blood biochemical parameters, blood samples were collected from the lambs in experiment 1 on the first and last days of the experiment, followed by analysis. Apparent digestibility in both experiments was determined using an indirect method with ash insoluble in hydrochloric acid as an indicator during three collection periods in both experiments. In experiment 1, collection periods lasted for 5 days: from day 15 to 19 (Period I), day 30 to 34 (Period II), and day 45 to 49 (Period III). In experiment 2, collection periods lasted for 6 days, and they were conducted from day 14 to 19 (Period I), day 29 to 34 (Period II), and day 44 to 49 (Period III). Apparent digestibility was determined for the following parameters: SM, organic matter (OM), CP, crude fat (SMa), crude fiber (SC), detergent fiber (neutral detergent fiber - NDF and acid detergent fiber - ADF), non-nitrogenous extractives (BEM) and non-fiber carbohydrates (NFC). At the end of the experiments, all lambs were slaughtered to examine the slaughter traits, chemical composition, and fatty acid profile of the meat.
	As an additional effect, an analysis of the economic sustainability of using chestnut tannins in the diet in both experiments was conducted. This analysis included feed costs per day (THd), feed costs per gain (THp), net profit (NP), and economic efficiency (EKI) based on the use of this tannin source.
	In experiment 1, intake of SM was identical in K and T2 (1.20 kg SM/day) and higher than in T1 (1.13 kg SM/day), primarily explained by lower intake of roughage in this group (hay). The setup and execution of experiment 2 allowed for similar SM intake in all three groups, averaging 0.97 kg DM, 0.99 kg DM, and 1.00 kg DM per day for KON, 10T, and 20T, respectively. Although it could have been expected that the astringent taste of tannins would lead to reduced intake, in the tested amounts, chestnut tannins did not affect this phenomenon. Differences in consumption are explained by the cumulative effect of variable microclimate parameters, occasional exposure to mild stress, and in experiment 2, changes in the diet and hierarchical relationships within the group. While the comparison of these two experiments can only be made to a limited extent, it is noticeable that consumption was higher throughout the duration of experiment 1. In addition, in experiment 1, consumption was higher than the Dutch standards (CVB, 2018) recommended, and almost without limitations, while in experiment 2, the amount of feed given was determined daily based on the group that consumed the least the previous day.
	Better feed efficiency is indicated by higher gains at the same level of consumption, suggesting a favorable effect of chestnut tannins. Consequently, the best SM conversion, followed by the highest KR, EP, and EEN values in experiment 1 were achieved by the T2 group (4.46 kg SM/kg gain, 0.0181, 1.03, and 27.95, respectively), while the least favorable parameters were observed in the K group (5.28, 0.0159, 0.83, and 23.26, respectively). In experiment 2, parameters were divided by gender, and feed efficiency was more favorable in male lambs in the tannin groups (10T and 20T, respectively) compared to the control (KON), with SM conversions of 4.50 and 4.33 kg DM/kg gain for 10T and 20T, respectively, while control had 5.05 kg SM/kg gain. Furthermore, in male animals, the tannin groups (10T and 20T) had higher KR values (0.0155 and 0.0157), EP values (1.47 and 1.60), and EEN values (33.15 and 34.79) than the control group, which had KR, EP, and EEN values of 0.0137, 1.19, and 26.58, respectively. A similar trend was observed in female lambs, with the best conversion in the 10T group (4.53) and the worst in the KON group (5.55).
	In experiment 1, the highest average daily and total gains were achieved by the T2 group (270.37 g/day and 16.23 kg), and the lowest by the K group (222.92 g/day and 13.37 kg), with significant differences (p < 0.05). The T1 group achieved gains of 259.26 g/day and 15.55 kg, but there were no significant differences compared to the other two groups (p > 0.05). Similarly, in experiment 2, the highest average daily and lifetime gains were achieved by the 20T group (230.00 g/day and 13.80 kg for males, 220.00 g/day and 13.20 kg for females), which were significantly higher (p < 0.05) than the gains achieved by KON (191.67 g/day and 11.50 kg for males, 174.17 g/day and 10.45 kg for females), while the results for 10T were not significantly different from the other two groups. Based on the gain results for the entire experimental period, in both experiments, it can be stated that chestnut tannins in the diet have a positive effect on lamb growth during fattening. If the entire experimental period of experiment 2 (from day 1 to day 60) is considered, the experimental groups achieved higher gains compared to the groups that did not receive tannins, indicating that chestnut tannins improve protein utilization.
	In experiment 2, apparent digestibility of SM and OM in the first collection period (from day 14 to 19) was slightly higher in KON (84.02% and 85.23%) compared to 10T (83.87% and 85.41%) and 20T (80.69% and 82.09%). CP digestibility followed a similar trend (78.44%, 78.42%, and 69.04% for KON, 10T, and 20T, respectively), while CF digestibility increased with the addition of tannins in the diet (83.53%, 89.15%, and 90.44%). Trends related to CF digestibility continued in the next two collection periods, indicating that chestnut tannins influenced better fat utilization due to changes in ruminal fermentation processes. Conclusions regarding CP digestibility are not straightforward due to the potential effect of tannins on increased flow of CP into the small intestine. In other words, increased CP flow also leads to an increase in its content in feces, which does not necessarily imply poorer utilization. This is supported by the fact that lambs in the tannin groups achieved higher gains than those in the control group.
	In experiment 1, an examination of basic blood parameters did not reveal any negative effects of chestnut tannins on fattening lambs.
	Although literature indicates that tannins can have different effects on the chemical composition and fatty acid profile of meat, these effects were not observed in this dissertation, as there were no statistically significant differences in these parameters among the groups in both experiments.
	The economic analysis showed that the economic efficiency index (EKI) in both experiments decreased with the addition of chestnut tannins to the diets, with average values of this parameter being 1.47, 1.29, and 0.98 in experiment 1 for K, T1, and T2, respectively. Depending on the diet and gender, EKI values ranged from 1.30 to 2.50 for KON, 0.74 to 1.56 for 10T, and 0.54 to 1.06 for 20T. This indicates that chestnut tannins reduce economic efficiency in lamb production. However, besides the cost of the used tannin product, this parameter depends on the parity of prices, which is currently unfavorable due to expensive feed and low live lamb prices. Chestnut tannins improved feed conversion and increased lamb gains, indicating better feed utilization, which is an advantage, especially in large farm systems. Considering that feed costs in livestock production constitute the largest part of total production costs, in large systems, each day of shortened fattening and every kilogram of saved feed represent significant cost savings, making chestnut tannins a potentially valuable addition to lamb production. In other words, the use of chestnut tannins in lamb fattening can be justified under such market conditions which includes cheaper feed production and higher market prices for live lambs. Cost reduction can primarily be achieved in large farms, so the potential use of chestnut tannins is particularly relevant in such systems.
	The presented results indicate that the use of chestnut tannins as additives in lamb diets can lead to improved production parameters without harmful effects. In the tested quantities, chestnut tannins did not affect reduced food consumption, which could have been expected due to their astringent taste. Additionally, their ingestion did not show harmful effects on the animals. The use of chestnut tannins improved feed utilization, resulting in higher gains and lower conversions compared to groups that did not consume tannins, primarily due to better protein utilization. The economic analysis found that, with the current price parity, adding chestnut tannins to the diet can lead to a financial burden in production, making it initially seem like an expensive option. However, if cheaper feed production and higher market prices for live lambs are achieved, their use can be justified. Reduction in production costs can be primarily realized in large farms, so the potential use of chestnut tannins is most suitable for such systems.",

AB  - The species Fusarium graminearum represents one of the most economically important factor that threaten agricultural production in the world. In addition to affecting yield reduction and grain quality, this species is of great importance due to its ability to synthesize mycotoxins. Knowing the toxicological profile of F. graminearum species is essential for agriculture and food industry, because trichothecene chemotypes (NIV, 3ADON, 15ADON) have different toxicological properties that directly affect human and animal health. In this study, 20 isolates of F. graminearum originating from maize and wheat were examined. DNA isolation was performed from the mycelium of the fungus using the commercial kit Dneasy Plant Mini Kit according to the manufacturer’s instructions. Chemotype detection was performed using two sets of specific primers (TRI3 and TRI12) designed for trichothecenes by Ward et al. in 2002. After the polymerase chain reaction was completed, the products were electrophoretically separated on a 1% agarose gel, and visualization was performed by staining with ethidium bromide and observing under UV light. Amplified fragments were read visually, and a positive reaction indicated the presence of DNA fragment of the expected size. All isolates of F. graminearum examined in this study had products of size 610bp at TRI3 and 670bp at TRI12, which indicates that isolates originating from Serbia belonged to 15ADON chemotype.

AB  - The aim of this research was to examine the influence of the year (production cycle) and laying age on the quality of eggs for consumption. Examination of certain properties of egg and shell quality was carried out over a period of three years continuously and in four evenly spaced time intervals (24, 35, 46, and 57 weeks of age). Determining the external quality of eggs included determining the weight and shape index. Examination of the internal quality of eggs included the determination of albumen height and Haugh units. At the same time, the quality of the eggshell involved the determination of the following properties: (weight, thickness, deformation, breaking force, and color of the shell). The obtained results showed that during three production cycles, the genetic progress of this hybrid was confirmed, which is primarily reflected in a statistically significantly higher (p<0.05) value of egg weight, egg white height, and Haugh's units in the third year compared to the first year examinations. Also, under the influence of this factor, statistically significantly higher values of weight and shell thickness and a darker shell color were determined in the third compared to the first year of research. No statistically significant differences were found for other examined parameters under the influence of this factor. In the presence of statistically significant influence (p<0.05), various laying ages were systematically examined for internal and external egg quality attributes alongside shell quality properties, excluding shell deformation. Egg weight increased significantly with increasing laying age, while shape index values, contrary to egg weight, decreased. The parameters of internal egg quality were worse with increasing laying age. Regarding the shell quality properties, it was found that the shell weight and thickness, similar to the egg weight, increased with the age of the layers, while the breaking force was found to be the lowest in the oldest layers. The interaction of both tested factors did not cause a statistically significant effect on tested egg quality traits.

AB  - Consumer demand for healthier foods has led the industry to look for alternatives to reduce high-fat levels. Dietary fibers such as inulin have emerged as promising substitutes for fat, increasing nutritional value and reducing fat absorption. The aim of this research was to formulate chicken cooked sausages in which the fat was replaced by inulin suspension at different levels. Four groups of sausages participated in the experiment: group K without fat replacement and groups 50%IN, 75%IN, and 100%IN with 50%, 75%, and 100% fat replacement, respectively. The results show a significantly higher process and cooking loss in the experimental groups compared to group K (p<0.05). Groups K and 50%IN had significantly better emulsion stability (p<0.05). Increasing inulin content significantly affected color characteristics, including L* (lightness), a* (redness), and b* (yellowness) (p<0.05). The experimental groups of sausages had a lighter color. By reducing fat, the caloric value of sausages decreased significantly and differed between groups (p<0.01). Inulin can be used to produce cooked sausages with reduced fat content and optimal physical and chemical properties. In addition to the reduced energy value, this meat product also has good nutritional characteristics.

AB  - This study aimed to assess the effects of different dietary levels of the protease enzyme
and sex on skin, bone and muscle yields and percentages of breast, drumsticks and thighs
as the most valuable carcass parts of broilers. A total of 300 one-day-old, mixed-sex
broiler chickens (Cobb 500) were randomly divided into 3 dietary treatments with
different levels of protease supplementation (group C: a standard diet without Ronozyme
ProAct; group E-I: a diet with 200 mg/kg Ronozyme ProAct and a 4% crude protein
reduction compared to the standard diet; and group E-II: a diet with 300mg/kg Ronozyme
ProAct and a 6% crude protein reduction compared to the standard diet). All diets were
maize- and soybean meal-based. Feed and water were provided ad libitum throughout the
49-day feeding trial. The results obtained indicate that the dietary treatments had no
significant effect on skin, bone and muscle yields and percentages of the drumsticks,
thighs and breast (P > 0.05), except for the breast muscle weight in the female chickens
(especially between the E-I and E-II groups), and the drumstick bone percentage in the
males between the C and E-2 groups (P < 0.05). In all three groups, the male chickens
exhibited higher weights of skin, muscle and bone in breast, drumsticks and thighs than
the female chickens, and the differences were not significant only in the skin weight of
drumsticks and thighs (P > 0.05). The females had a higher yield of muscle tissue in
breast and drumsticks, a higher percentage of skin in drumsticks and thighs, and a lower
percentage of bone in drumsticks and thighs than the males (P < 0.05). Major differences
resulted from the effect of broiler sex, whereas the dietary treatments containing 3 levels
of protease supplementation had a very small effect on the yields and percentages of skin,
bone and muscle in breast, drumsticks and thighs.

AB  - Gene expression at the phenotypic level varies due to a number
of influences from the environment in which the animals are reared. Ignoring this
reality or due to insufficient knowledge, farmers are often disappointed when
choosing a population of sheep when they do not get the production results that the
breed achieves where they bought it. The investigation of the reproductive and
production characteristics of parent herds of Sjenica sheep was conducted on four
farms. In the research, it included a total of 921 lambs and 474 sheep. The
influence of sheep body weight on the weight of lambs at birth within a farm was
analyzed. Based on the research conducted on the sheep population and after the
obtained and processed data, we can state the following: certain differences were
found in the fertility of sheep depending on the farm and body weight. We also
perceived that certain differences in the body weight of the lambs are evident
depending on the weight group of the sheep and the farm where the sheep were
raised. All of the above leads us to the general conclusion that management is
extremely important in sheep farming. If the selection of the breeding population is
carried out correctly and adequate measures of keeping, nutrition and reproduction
are applied, success is guaranteed.

AB  - The aim of the study was to examine the influence of the rearing system and age on the phenotypic correlation of the physical
properties of the eggs of the Banat naked neck layers. In both examined systems (extensive and semi-intensive system) there
were 50 Banat naked neck layers each. The egg properties were examined at three evenly distributed time intervals (40, 45 and
50 weeks of age) in the period from May to July. In order to determine the external properties of egg quality, three basic measures
were observed: egg weight, egg length and egg width. Based on the measured length and width of the eggs, the egg shape index
was calculated, and subsequently the volume and surface area of the eggs were determined. For each examined factor, the
correlation between the mentioned characteristics was determined. The obtained results showed a significant effect of the
rearing system on all examined egg properties (Р < 0.05), while the influence of age as well as the interaction of the two examined
factors had no significant effect. The highest correlation among all investigated factors was found between surface area and egg
volume.

properties of the eggs of the Banat naked neck layers. In both examined systems (extensive and semi-intensive system) there
were 50 Banat naked neck layers each. The egg properties were examined at three evenly distributed time intervals (40, 45 and
50 weeks of age) in the period from May to July. In order to determine the external properties of egg quality, three basic measures
were observed: egg weight, egg length and egg width. Based on the measured length and width of the eggs, the egg shape index
was calculated, and subsequently the volume and surface area of the eggs were determined. For each examined factor, the
correlation between the mentioned characteristics was determined. The obtained results showed a significant effect of the
rearing system on all examined egg properties (Р < 0.05), while the influence of age as well as the interaction of the two examined
factors had no significant effect. The highest correlation among all investigated factors was found between surface area and egg
volume.",

AB  - Milk fat content stands out as a crucial production trait in cows, and this study delves into its variability based on various factors. The
research investigated how the housing method (large farm or individual producers), origin (domestic-rearing or imported cows), and
calving season collectively impact this trait. Cows reared on the farm exhibited a higher milk fat content compared to those raised by
individual producers. Additionally, primiparous cows from domestic rearing displayed lower milk fat content than their counterparts
of imported origin. Among primiparous cows on the farm, those calving in the summer and autumn produced the highest milk fat
content. Conversely, primiparous cows calving in the spring season and raised by individual producers recorded the lowest milk fat
content. The statistical analysis revealed a highly significant influence of calving season, with a noteworthy interaction among housing
method and origin on the observed trait. The significance ranged from statistically highly significant (P ≤ 0.01) to statistically very
highly significant (P ≤ 0.001).

AB  - Soil pH is one of the most important limiting factors for crop cultivation, including maize. About 30-40% of the world's arable land is acidic, and over a billion ha is alkaline. Today, there are 205 million ha of arable land under maize in the world, so it ranks third in area after rice and wheat. Maize hybrids have wide genetic variability and high pH tolerance. We tested the tolerance of maize hybrids seedlings of ZP 4708 and ZP 5797 to pH 5, 6, 7, and 8. Results showed that hybrid ZP 4708 has a higher adaptability to low and high pH, due to the higher value of germination energy (GE), shoot length (ShL), shoot fresh weight (ShFW), shoot dry weight (ShDW), germination rate index (GRI), and seedling vigor index (SVI) than hybrid ZP 5797. Results further showed, on average for hybrids, that pH 5 and pH 8 significantly decreased the GE, root length (RL), ShL, root fresh weight (RFW), ShFW, root dry weight (RDW), shoot fresh weight (ShDW), and SVI. These parameters did not differ significantly between pH 6 and pH 7. Seed germination was not affected by the pH, indicating that the seed vigor of both hybrids supports full germination potential. However, it could be expected that exposure to the lowest and highest pH values of the medium could affect seedlings growth in the field conditions, even though germination is high. SVI showed a positive and significant correlation with all investigated parameters, except germination (G) and relative seedling water content (RSWC).

AB  - This dissertation describes the synthesis, characterization and crystal structure of the complexes [CuL1Cl]BF4 (1), [CuL1Cl]NO3 (2), [Cu2L12Cl2](BF4)2 (3) and [Ni2L12(μ-1,1-N3)2(N3)2]6H2O (4), obtained in the reaction of the corresponding Cu(II) and Ni(II) ions and the ligand 
(E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride (HL1Cl) and complexes [Ni2L22(µ-1,1-N3)2(N3)2]∙2H2O (5a) and [Ni2L22(µ-1,1-N3)2(N3)2]∙4H2O (5b) obtained in the synthesis of Ni(II) ions and the ligand (E)-N,N,N-2-oxo-2-(2-(1-(thiazol-2-
-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride, (HL2Cl). All mentioned complexes were characterized in detail in the solid state by X-ray structural analysis, elemental analysis and IR spectroscopy, while for complexes 5a and 5b magnetic susceptibility was also measured.
In all complexes 1–5, ligands HL1Cl and HL2Cl are tridentately coordinated via NNO donor set of atoms in a deprotonated, formally neutral, zwitterionic form. In the case of complexes 1 and 2, metal ions with the HL1Cl ligand form mononuclear complex, while in the case of complexes 3 and 4 with the same ligand, binuclear complex is formed. Ligand HL2Cl with Ni(II) ions builds binuclear complexes 5a and 5b. Complexes 5a and 5b were obtained from the same solution, with complex 5a found only in trace amounts.
DFT calculations were performed for all complexes, the results of which were in accordance with the experimental data. DFT calculations showed that in the case of mononuclear complexes 1 and 2, there is a weak coordination bond between the central metal ion Cu(II) and the anions BF4– i NO3–, which is of a typical ionic type. For complex 3, DFT calculations showed that the complex exists as a binuclear species, in which two Cu(II) ions are connected to each other by bridging Cl– ligands and that the BF4– anion is not involved in coordination with Cu(II). In the case of complex 4, DFT calculations showed that independently of the applied functionals, ferromagnetic coupling exists between the metal centers. In complexes 5a and 5b, the calculated magnetic interaction according to the DFT approach with meta-hybrid M06-2X and doubly hybrid B2PLYP and PWPB95 functionals shows that in all cases, the model systems based on 5b have lower energy level than those based on 5a. Also, in the case of the optimized structures 5a* and 5b* (at the BP86-D4/TZP level of theory), the optimized structure 5b* has a lower energy state. For complexes 5a and 5b, a temperature-dependent magnetic susceptibility was also measured, which showed that intramolecular interactions between Ni(II) centers are ferromagnetic in nature.

The influence of genotype and parity of sows on litter size traits (Number of live born piglets -NLBP, number of stillborn piglets -NSP, total piglets born -TPB, number of reared piglets and litter weight) and lactation duration was examined. Research showed that the highest number of live born piglets was in F1 crossbreeds (13.36 NLBP), while among purebreds the highest NLBP was in the Landrace breed (12.44 NLBP) and Large White (12.17 NLBP). Looking at parities for all tested genotypes, NLBP in the first litter was over 11.53 piglets. For breed L and LW, the highest NLBP was in the fourth litter 12.88 and 12.55 piglets. F1 crosses LxLW (♀Lx♂LW) also had the highest NLBP in the fourth litter 12.85 piglets. For the genotype F1 crosses LWx L (♀LWx♂L), the highest average number of live-born piglets was 12.32 piglets in the second and third litters. Variation in litter size at birth and weaning by genotype and parity was statistically significant (P<0.01), except for the number of stillborn piglets of L sows by parity, where a significant difference was found (P<0.05).

AB  - There are strong indicators of the link between diets and increased burdens of obesity, cardiovascular diseases, diabetes and some cancers. Healthy dietary patterns were defined as diets that are high in fruits, vegetables and non-fat dairy (low in saturated and trans fats). The aims of this study were to determine the fatty acid (FA) profile of meat (poultry, pork, lamb and beef) and the calculated atherogenic index (AI) and thrombogenic index (TI). Poultry, pork and lamb contained more monounsaturated fatty acids (MUFAs) than saturated fatty acids (SFAs). Linear discriminant analysis (LDA) demonstrated that the first discriminant explained 56.11% of the total variance and the second discriminant explained 23.85% of the total variance. The established p value of Wilks' test was p < 0.0001. By canonical correlation, the first and the second discriminant functions in the LDA were established as 0.995 and 0.995, respectively. AI and TI values of less than 0.5 and 1.0, respectively, were previously advised. The obtained AI values in poultry (0.37-0.45) were lower than those in pork (0.50-0.53), lamb (0.54) and beef (0.93) meats. The obtained TI values in poultry (0.81-0.87) were also lower than in pork (1.09-1.18), lamb (1.44) and beef (1.93) meats. Beneficial nutrition habits, i.e., nutrition according to the food pyramid and a Mediterranean diet, should reduce the rate of coronary heart disease and result in better health outcomes for consumers.

AB  - Considering that recently there are more and more different options and dietary trends, vegetarianism is presented as a possible solution for quality nutrition with less impact on the environment, it is necessary to analyze how true such a premise really stands. A plant-based diet implies the consumption of foods that come from plants with some or no components of animal origin. This diet could have some positive effects on the human health of adults (lower risk of chronic diseases such as heart disease, type 2 diabetes, certain cancers, and obesity) but
only well balanced and supplemented while in infants, children, and adolescents could cause severe deficiencies in vitamin 9 and vitamin 12 affecting the growth, cognition, social development, and expression of depression. From the point of environmental sustainability, further research is necessary to distinguish the accurate footprint of a plant-based diet as well as of animal production. Finally, it is up to each person to decide, hopefully, based on knowledge and responsibility, what kind of diet will follow. From the point of those engaged in animal
production, it is up to us to ensure efficient and sustainable production of high quality
animal products, because the market is only growing.

AB  - The morphometric characteristics of the gonads of male autochthonous breeds of pigs in the
Republic of Serbia were examined. The following breeds are included: lasasta mangulica (Swallow-Bellied Mangalitsa), Moravka and Resavka. There were 3 age categories divided by body mass within the group of Swallow-Bellied Mangalitsa. The first group are animals of average body mass 20 kg (n=11). The second group is the average body mass of 45 kg (n=9), and the third group are pigs of body mass of 100 kg (n=13). Number of Moravka male were 8, until number of Resavka was 7 adult animals. The morphometric properties that were investigated were: ZAPSAEP- Volume of testes with the epididymes; ZAPBEZEP - Volume of testes without the epididymes; ZAPEP-volume of epididymes; MASSAEP- Weight of testes with the epididymes; MASBEZEP- Weight of testes without the epididymes; MASEP- Weight of epididymes; DUŽSAEP- Length of testes with the epididymes; DUŽBEZEP- Length of testes without the epididymes;
DUBBEZEP- Thickness of testes; ŠIEBEZEP- Width of testes; OBBEZEP- Circumference of testes. The characteristics of length and thickness in the youngest group of Mangalitsa had a coefficient of variation for the left and right testis of less than 30%, as well as for the group up to 45 kg of body weight. Length traits in the oldest group of Mangalitsa had smaller coefficients of variation for the left compared to the right testis (12.70; 10.86 toward 13.76; 12.22%). The absolute size of the left testicle was larger in non-castrated male of the Mangalitsa breed, as indicated by all the morphometric measurements taken on the testicles. The characteristics of testicular volume varied within the Moravka breed, in contrast to the Mangalitsa, in Moravka males, a larger volume of testicles with the epididymis on the right side compared to the left was determined, which is a consequence of the larger volume of the right epididymis. In contrast to the Moravka, lower values of the characteristics of the volume of the right testicle compared to the left were found in male
Resavka. Traits of volume, length, depth, and weight in Mangalitsa males had coefficients of variation of less than 30% for left and right testis. In sexually mature animals, the correlation between morphometric measures is strong and positive, which allows us to take one measure (which is the simplest to take), to gain an objective insight into the size of the testes. The association of age and body mass at slaughter with a number of morphometric traits of the Mangalitsa breed was moderate to strong with a positive sign. The connection between the morphometric characteristics of the testicles and the production characteristics of male pigs of the Moravka breed, unlike the Mangalitsa, looking at the established correlation coefficients in the Moravka, it is not possible to draw clear conclusions when it comes to the connection of these groups of characteristics. Within the Resavka breed, of the production traits, only the average lifetime daily gain has a strong correlation with the trait of testis length without epididymis, but with a negative sign.

AB  - The greenhouse effect has led to a changed precipitation regime, an
increase in the average temperature, the occurrence of extreme meteorological
events (droughts and floods) and the like. All this harms the yield and quality of
feed, the incidence of mycotoxins in food, reduced productivity of animals, the
incidence of new and non-specific pathogens, the development of diseases, etc.
According to the FAO and the World Bank, the countries most affected by climate
change are the countries of Central Europe and the Mediterranean. The population
of people living in rural areas and engaged in agriculture will be particularly at
risk. With difficult working and living conditions and reduced incomes, there will
be an increased migration of the population to the cities. The simultaneous decline
in agricultural production and increased food demand will lead to a food supply
crisis (FAO predicts that by 2050 the global population will increase to 9.6 billion
people, resulting in a demand for 70% more food than in 2013).Cattle production is
affected by the climate in different ways, directly and indirectly. Livestock
condition, production level, reproductive performance, morbidity and mortality are
correlated with climatic conditions. The most pronounced negative impact on the
health and welfare of animals is a phenomenon called heat stress. Exposure to
microclimatic conditions characterized by a combination of high temperature and
air humidity overcomes the ability of animals to maintain normal thermoregulation
and constant body temperature, leading to an increase in body temperature that
exceeds physiological limits. In addition to the direct effects of heat stress on the
productivity, reproduction and health status of animals, global warming also affects
animals indirectly through reduced soil fertility, water availability, crop yields,
quality of plant nutrients and the circulation of pathogenic agents. Finding a
solution to mitigate and prevent the consequences of unfavourable climatic and
microclimatic conditions is a challenge for the entire scientific and professional
community, but also for every cattle breeder. Solutions can be biological and
technological. Biological ones refer to the animals themselves (breed selection,
selection for functional traits, selection for adaptability to heat stress, use of
genomic selection, artificial insemination programs, herd size). Technological
solutions relate to how animals are kept (free system, in outlets with canopies, use
of grazing), facilities (new materials and technical solutions in the construction of
facilities, use of insulating materials, regulation of microclimate conditions in
facilities - ventilation and air humidity), nutrition and feeding (feeding method,
feeding time, use of new types of feed, continuous water supply, etc.).The goal of
agricultural production is to ensure food security in the face of climate change, and
it is one of the most demanding tasks facing humanity

AB  - In recent years, numerous plans and programs, instructions,
recommendations, scientific opinions, analysis, reports, best practices, regulations
and other type of publications have been published in publications, other than in
journals and symposiums proceedings that consider indicators of biosecurity on
cattle and pig farms in order to improve their health and productivity. These
indicators were created mainly as results of research in numerous national and
international projects, which consider key indicators and prescribe on-farm
assessments of biosecurity on cattle and pig farms. In the assessments of the
biosecurity level in different systems of rearing and accommodation on cattle and
pig farms, the need to determine indicators was observed. The publication about
plans and programs, instructions, recommendations, scientific opinions, analysis,
reports, best practices and regulations, related to biosecurity level contain
numerous indicators. The analysis of these publications aims to determine the main
characteristics of the existing and to generate ideas to define new biosecurity
indicators of the animals on cattle and pig farms.

recommendations, scientific opinions, analysis, reports, best practices, regulations
and other type of publications have been published in publications, other than in
journals and symposiums proceedings that consider indicators of biosecurity on
cattle and pig farms in order to improve their health and productivity. These
indicators were created mainly as results of research in numerous national and
international projects, which consider key indicators and prescribe on-farm
assessments of biosecurity on cattle and pig farms. In the assessments of the
biosecurity level in different systems of rearing and accommodation on cattle and
pig farms, the need to determine indicators was observed. The publication about
plans and programs, instructions, recommendations, scientific opinions, analysis,
reports, best practices and regulations, related to biosecurity level contain
numerous indicators. The analysis of these publications aims to determine the main
characteristics of the existing and to generate ideas to define new biosecurity
indicators of the animals on cattle and pig farms.",

AB  - Traditional dry fermented sucuk sausages were made from beef and formulated with 10, 20 and 30% of added fat (LF, MF and HF group, respectively). The production was carried out in a traditional smoking house, and fermentation and ripening lasted 28 days. After the end of the production process, colour (CIE L*a*b*), texture TPA parameters and sensory quality were analysed. An increase in fat content significantly affected the reduction in TPA values for hardness, springiness, cohesiveness and chewiness (p<0.01). Data obtained in this study indicate that sausages with higher fat content were less firmly bound (lower cohesiveness) and less elastic (lower springiness). Additionally, fat content significantly influenced an increase in lightness (L*) and yellowness (b*) and a decrease in redness (a*) of sucuk sausages (p<0.05). The lowest sensory scores were obtained for HF sausages, especially for consistency, cut appearance and taste.
