AB  - This study investigated the possibility of using morphometric measurements to differentiate the autochthonous Serbian White goat breed from Saanen and Balkan goats, which were used as sire and dam breeds in its creation. For this purpose, a multivariate discriminant analysis was used. A total of 11 morphometric traits were measured in 98 does of 3 breeds: Saanen (n = 28), Balkan (n = 28), and Serbian White (n = 42), aged 2 to 7 years, in 4 different locations. Univariate analysis of variance revealed a significant difference in body measurements of all three breeds, with Saanen goat being the largest in format and Balkan the smallest. Discriminant analysis extracted six out of eleven tested morphometric traits with the strongest discriminatory power: heart girth, head length, chest depth, head width, pelvic width, and body length. Mahalanobis distances were significant between all three genetic groups. The discriminant function correctly classified 95.24% of the Domestic White goats investigated to their source group. The classification accuracy of the function was cross-validated and indicated an overall success rate of 91.84%. The results of this research showed that there was a clear separation between Serbian White, Saanen, and Balkan goats. The present findings could help a more rapid field assessment of Serbian White goats.

AB  - Meat colour was evaluated in 36 goat kids of both genders equally from three breeds: Alpine, Balkan and Serbian white breed. Animals were slaughtered at 18 kg of body weight and three muscles were analysed for colour characteristics and pH value: m. longissimus lumborum, m. psoas major (tenderloin) and m. semimembranosus. pH values differ significantly only for m. longissimus lumborum muscle, whereas Balkan kids had a significantly higher pH value than Alpine and Serbian white (p<0.001). The goat breed significantly affected meat CIEL*a*b* values for all muscles analysed. Lightness (L*) was generally the highest for Balkan and lowest for the Alpine breed. The differences in redness (a*) and Chroma values (C*) were not significant, while the yellowness only differed for m. longissimus lumborum muscle, whereas Serbian white kids had higher b* values compared to Alpine kids. As a colour saturation characteristic, the hue angle was higher in meat from indigenous breeds (Balkan and Serbian white) than in the Alpine breed.

AB  - The research included a total of 921 lambs, 474 ewes and 8
sjenicke sheep rams from 4 different farms. The aim of the research was to
examine the influence of the farm, cultivation technology and the influence of rams
within the farm on production indicators. Statistical analysis showed that the body
weight of lambs at birth ranged from 3.37 to 4.03 kg (average 3.68 kg), at 30 days
from 11.51 to 12.41 kg (average 12.07 kg) and from 90 days from 27.82 to 29 kg
(average 28.65 kg). A statistically highly significant influence of the farm was
determined (P<0.01) on the body weight of lambs in all three control periods, as
well as on the body weight of sheep and on the fertility of sheep. The influence of
the ram on the body weight of the lambs at birth was statistically very significant
within the farm (P<0.01). When it comes to the percentage share of birth type by
farm, farm 1 had the most singletons (59.13%) both within the farm and in
comparison between other farms, while there were fewer twins (40.87%), and
triplets were not identified. On the other farms, the percentage of twins was the
highest, and triplets were also present, while on farm 4 there were also quadruplets,
lambs born as quadruplets (3.28%).

AB  - Lipska sheep is an autochthonous Serbian population from the
group of Pramenka (Zapfel) sheep, bred in the area around Smederevo, Požarevac
and Mladenovac. The average weight of male animals (BW) is 95 kg and 62 kg of
female animals. Other measurements of female animals are: wither height (WH) 74
cm, body length (BL) 78 cm, chest width (CW) 23 cm, chest depth (CD) 40 cm and
hearth girth (HG) 91 cm. In the last sixty years, adult female animals gained in
average ten kilograms of weight. Other linear measures also increased. The
increase is a consequence of better animal management, especially improved diet.
Since the reduction of the size of the population, larger animals have dominated,
which probably caused the change in the genetic constitution of the breed. Female
animals of Lipska sheep are higher compared to the animals of other fifteen
Pramenka breeds with the exception of Istrian sheep. The area from which Lipska
sheep originates has better soil and richer vegetation compared to the areas of other
Pramenka breeds. Partial correlations corrected for weight between individual
linear measures were positive, with values between 0.196 and 0.814. Most
correlations range between 0.30 and 0.55. Body measurements were studied with
ANOVA on females only. The effect of flock influenced all linear measures with
the exception of CW, whereas the age of animals had no effect on BL, CW and
CD. The increase of individual linear measures was 0.5 to 2.1 mm per kg of BW.
The increase of most body measurements from the first to the fifth year was
statistically significant (P<0.05).

AB  - In order to evaluate the effect of raw meat's freezing/thawing
process on meat products produced from them, frankfurter's quality was monitored.
Fresh beef meat was grounded and separated into two lots – the first lot was
immediately used in the preparation of frankfurters (G1F), and the other lot was
frozen and stored at -18°C for 4 weeks, when it was used in the preparation of the
second group of frankfurters (G2F). Physicochemical and technological properties
were investigated on fresh (CG-FM) and thawed meat (G-F/TM) samples and the
frankfurters made from these samples. Frozen storage significantly affected
(p<0.05) moisture, TBA value, instrumental color parameters (L*a*b*), WHC,
total pigment, and total heme pigment in the raw meat samples; some frankfurters
characteristics, such as moisture, L*(lightness), a* (redness) and b* (yellowness)
were affected (p<0.05). However, the differences in the final products' process
loss/cooking loss/frying loss and FRP were not significant. The sensory evaluation
did not show any significance between the two groups of frankfurters It can be
concluded that the frozen storage of minced beef meat for 4 weeks at -18°C and the
consequential thawing process (at 4°C for 24h) does not significantly affect the
overall acceptability of frankfurters prepared from them. However, effects on the
marked changes in instrumental color are apparent.

AB  - Sheep (Ovies aries) are mainly seasonal polycyclic animals. Sperm production is influenced by many factors, including daylight length, climate temperature, humidity, and melatonin secretion, with females becoming fertile in early autumn and remaining fertile through mid-winter (October-February). Seminal plasma is a complex fluid that is functional modulator of sperm function known to inhibit and stimulate sperm function and viability. Some seminal plasma proteins are capable of binding to the sperm plasma membrane and have an important role in sperm capacitation and egg fertilization. A variety of enzymes in the seminal plasma protect the sperm membrane from ROS-induced damage and lipid peroxidation through the activity of the antioxidant enzyme defense system. Regarding this, the aim of our study is to determine the biochemical changes that occur during the breeding campaign of the species Ovies aries and beyond. To fulfill the set goal, we have examined 6 ejaculates spectrophotometrically. As a result, we found higher antioxidant enzyme protection outside the insemination campaign in glutathione (GSH) concentration and glutathione peroxidase (GPx) activity and non-significant differences in glutathione reductase (GR) activity. The enzyme activities of lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) were higher during breeding season of the animals. In conclusion, a higher protective antioxidant system may help ensure adequate sperm fertilization potential when reproductive conditions are suboptimal. However, further research is needed to determine the mechanisms of action of the antioxidant enzyme and the relationships between indicators for determining sperm quality.

AB  - Poljoprivredna proizvodnja u Republici Srbiji predstavlja značajnu privrede. Stočarstvo pre svega karakterišu usitnjena porodična gazdinstva, koja se tradicionalno bave ovom delatnošću. Ovčarstvo predstavlja važnu granu stočarstva u Republici Srbiji, gde se na preko 155 000 poljoprivrednih gazdinstava gaji ukupno preko 1,7 miliona ovaca. Najveći deo populacije ovaca čine autohtone rase, u prvom redu različiti sojevi pramenke, zatim, u značajno manjem broju cigaja, koje se najčešće gaje u poluekstenzivnim sistemima. Mnogi sojevi autohtonih rasas imaju ugrožen status i neophodno je unaprediti mere očuvanja i zaštite ovih dragocenih autohotnih genetskih resursa, koji imaju značajan potencijal u održivoj poljoprivrednoj proizvodnji. Posebna pažnja treba da se posveti odabiru priplodnih ovnova, zbog toga što je njihov uticaj na populaciju najveći, s obzirom na činjenicu da jedan kvalitetan ovan, u sezoni parenja, upari preko 40 ovaca i ostavlja svoje brojne potomke. Iz tog razloga, prilikom izrade selekcijskih programa za određenu rasu, posebnu pažnju treba posvetiti priplodnim ovnovima i njihovim proizvodnim i reproduktivnim karakteristikama. Pored ostalih selekcijskih kriterijuma, kliničkim pregledom genitalnih organa i morfometrijskom analizom testisa pri odabiru kvalitetnih priplodnih ovnova u značajnoj meri se može poboljšati, ne samo zdravlje zapata, već i kvalitetne rasne odlike i brojnost populacije. Poznato je da je pored zdravstvenog statusa genitalnih organa, kapacitet testisa za proizvodnju sperme u srazmerom sa obimom testisa (veličina testisa). Ustanovljeno je da ovnovi sa većim obimom testisa ostavljaju veći uticaj na populaciju i mogu da se pare sa većim brojem ovaca. Oni ostavljaju veći broj potomaka, te svoje kvalitativne i kvantitativne rasne odlike mogu brže širiti u populaciji u odnosu na priplodnjake koji imaju manje testise, koji stvaraju manje sperme. Na osnovu literaturnih podataka, koji su proistekli iz opsežnih ispitivanja zaključeno je da priplodni ovnovi starosti preko 1,5 godine, sa zdravim genitalnim organima, moraju imati obim testisa najmanje 33 cm. Idealno bi bilo da svaki priplodnjak ima obim testisa ≥ 35 cm zbog toga što tada može uspešno da pari i preko 40 ovaca tokom sezone parenja. U zemljama sa razvijenim ovčarstvom, ova saznanja čine glavne selekcijske smernice i kriterijume, te je shodno tome, cilj da kvalitetni priplodnjaci imaju obim testisa ≥ 38 cm. Lipski soj pramenke predstavlja autohtonu rasu Republike Srbije, koji je prema klasifikaciji Pravilnika o genetičkim resursima do 2019. godine spadao u I kategoriju (kritično ugrožene rase), sa brojem priplodnih grla od oko 800 komada. Zahvaljujući subvencijama, brojnost populacije se povećala i u 2021. godini je postignuto 2 000 registrovanih priplodnih jedinki, tako da ona nije više kritično ugrožena, već spada u kategoriju „potencijalno ugroženih“. Ispitivanja populacija lipskog soja pramenke su dokazala da je zdravlje genitalnih organa priplodnih ovnova dobro, prosečan obim testisa je 38,35 cm, ali je opseg varijacija velik. Ova vrednost podrazumeva odličan prosek na nivou cele populacije, ali zbog toga što je većina zapata mala (do 20 priplodnih jedinki) i često samo sa jednim ovnom u zapatu, ovnovi sa testisima nedovoljnog obima mogu imati nepovoljan uticaj, ne samo na zapat u kome se gaji, već i na celu populaciju lipske ovce. Sa aspekta očuvanja i unapređenja ovih dragocenih autohtonih genetičkih resursa, poželjno je osavremeniti i selekcijski pristup koji uključuje kriterijume vezane za genitalni trakt, sa ciljem da svaki zapat ima kvalitetnog ovna.
AB  - The agriculture represents an important branch of economy in the Republic of Serbia. Animal production is mainly based on traditional small family households. Sheep production is an important branch of agriculture in the Republic of Serbia, where a total of 1.7 milion sheep are reared in over 155.000 households, mainly under semiextensive menagement. The majority of sheep are autochthonous breeds and local types adapted to the local enviornment. Because of the endangered status of the autochthonous sheep breeds, conservation and improvement of these precious population is needed, as they have a major potential in the sustainable agricultural production. The main focus should be given to the selection of breeding rams, as they have the biggest impact on the population quality. One high quality breeding ram can mate over 40 ewes over the matin season and leave offspring. Taking this in mind, when the selection criterias are defined for a breed, a special attention should be given to the ram, to its productive and reproductive traits. Among other selection criteria, the clinical assessment of the genital tract with a special attention on scrotal circumference could result in better health and quality of the population. It is well known that rams with bigger scrotal circumference (bigger testicles) can have a better reproductive capacity and can serve more ewes in the mating season, what makes a stronger impact of rams on the population quality. In countries with specialized sheep production these characteristics are included into the selection measures and breeding rams older than 1.5 years with healthy genitals should have scrotal circumference of minimum 33 cm, and the ideal score means that the ram should have ≥ 35 cm, and the elite ones ≥ 38 cm. The Lipe sheep is a local autochthonous breed of the Republic of Serbia, which has a breeding population size of 800 animals in 2019. According to the national legislation that time it had a status of a critically endangered breed. As a result of higher subsidies for the last few years, the population size rises and im 2021 reached 2000 breeding animals which means it got a status of potentially endangered breed. Assessment of the genital tract of breeding rams of the Lipe sheep showed good health of the genitalia, with an average scrotal circumference of 38.35 cm, but with evidence of big variations. The average scrotal circumference of 38.35 cm means an excellent result on a population level. Eventhough the overall scrotal circumference is excellent on the population level, because of the fact that most of the herds are small (up to 20 breeding animals) with only one breeding ram, the animals with insufficient values of scrotal circumference (≥ 33 ) could have negative results not only at the herd level, but also at the population level of the endangered Lipe sheep. With the aim to improve and save the endangered autochthonous rare breed and ensure a high quality elite breeding rams in each flock, it is necessary to update the selective measures with a new criteria regarding the assessment of the male genital tract.

AB  - Autochthonous breeds are the pillar of sustainable animal production worldwide. From a total of 8719 livestock breeds, 26 percent are classified as at risk of extinction, 13 percent as not at risk, 6 percent as extinct and 55 percent as being of unknown risk status. Therefore, conservation is of high priority. The Podolian cattle is one of the most endangered breed from the list of native breeds of livestock in Serbia. In 2021 only 338 breeding animals were registered. The breed is known as a precious resource of the local landscape enrichment, national heritage and history. According to the population size of the Podolian cattle, a slight increasing tendency can be evidented. The population size is variable (154 breeding animals in 2009, 252 in 2010, 270 in 2011, 260 in 2012, 264 in 2013, 306 in 2014, 258 in 2015, 263 in 2016, 338 in 2017, 317 in 2018, 357 in 2019, 416 in 2020 and 338 in 2021). The Podolian cattle population in Serbia belongs to the I group (critically endangered). Over the time the governmental subsidies influenced the overall slight increase of the number of breeding animals, but the population size is not stabile. Improved conservation program should be applied to save the autochthonous endangered breed suitable for heritage oriented sustainable production in an authentic environment.

AB  - The aim of this study was to investigate the effects of chestnut tannins in metabolizable
protein deficiency, on dry matter (DM) intake, growth performance of finishing lambs,
feed efficiency and digestibility of nutrients. The study included 30 crossbred lambs,
blocked by body weight (BW) and divided into three groups, depending on the concentrations of added chestnut tannins in the rations (0, 10 and 20 g/kg DM for CON, 10T and
20T group, respectively). Rations were determined by BW and expected average daily
gain (ADG), with a deficiency in metabolizable protein of about 15%. All groups received
the same amount of daily feed. Dry matter intake, ADG and indicators of efficiency such
as the Kleiber ratio (KR) and protein efficiency ratio (PER) were estimated. The digestibility of the rations was determined in three collection periods. Dry matter intake did not differ among groups. Growth performances for the whole experiment were significantly better for the 20T group than CON (p < 0.05), while no differences were established for
group 10T. Group 20T achieved the highest ADG and total gain (228 g/day ± 27.8; 13.7 kg
± 1.7), with the best average conversion of dry matter (4.4 kg DM/kg BW), KR (15.6), and
PER (1.6). In all three collections, dry matter and crude protein digestibility was higher
for CON, while the digestibility of ether extract was higher for the 20T group than CON.
Based on these results, it can be concluded that a ration of chestnut tannins in the concentration of 20 g/kg DM, in conditions of protein deficiency, can have a positive effect on
lamb performances. This can be partially explained by the ability of tannins to form complexes with proteins, which can change intestinal protein flow and utilization.
AB  - Das Ziel dieser Studie war, die Wirkungen von Kastanien-Tanninen in Rationen mit
unzureichender Versorgung mit metabolisierbarem Protein auf die Aufnahme von
Trockenmasse (DM), die Wachstumsleistung von Mastlämmern, den Futteraufwand und die Verdaulichkeit von Nährstoffen zu untersuchen. Die Studie umfasste 30 Kreuzungslämmer, die durch das Körpergewicht (BW) und die Konzentrationen von zugesetzten
Kastanien-Tanninen in der Nahrung (0, 10 und 20 g/kg DM für die Kontrolle, 10T- bzw.
20T-Gruppe) in drei Gruppen unterteilt wurden. Die Rationen wurden durch das Körpergewicht (BW) und die erwartete durchschnittliche tägliche Zunahme (ADG) mit einem
Mangel an metabolisierbarem Protein von etwa 15% definiert. Alle Gruppen erhielten
die gleichen Futtermengen. Die DM-Aufnahmen, ADG-Werte, und Verwertungsgrößen
wie das Kleiber-Verhältnis (KR) und das Protein-Effizienz-Verhältnis (PER) wurden
geschätzt. Die scheinbare Verdaulichkeit wurde in drei Sammelperioden ermittelt. Die
DM-Aufnahme unterschied sich nicht zwischen den Gruppen. Die Wachstumsleistungen
für das gesamte Experiment waren für die 20T-Gruppe signifikant besser als für die
Kontrollgruppe (p < 0,05), während für die 10T-Gruppe keine Unterschiede festgestellt
wurden. Gruppe 20T erreichte den höchsten ADG und Gesamtzuwachs (228 g/Tag
± 27,8; 13,7 kg ± 1,7) mit der besten durchschnittlichen Umwandlung von Trockenmasse
(4,4 kg DM/kg BW) und den günstigsten Werten für KR (15,6) und PER (1,6). In allen
drei Sammelperioden war die Verdaulichkeit von DM und Rohprotein bei der Kontrolle
höher, während die Verdaulichkeit des Rohfetts bei der 20T-Gruppe höher war als bei der
Kontrolle. Aus den Ergebnissen kann geschlossen werden, dass Kastanientannine in
einer Konzentration von 20 g/kg DM Futter bei Proteinmangel einen positiven Effekt auf
die Leistung von Mastlämmern haben können. Dies kann teilweise durch die Fähigkeit
von Tanninen erklärt werden, Komplexe mit Proteinen zu bilden, die den Proteinfluss
durch den Verdauungstrakt und seine Verwertung verändern können.

AB  - The current study aimed to examine the percentage changes of
viability sperm and the activity of the enzymes LDH, ALP, GOT / AST, GPT /
ALT in the sperm plasma of Lacaune rams, before and after cryopreservation. For
this purpose, five rams were examined, and two ejaculates were obtained from each
ram. Ejaculates are collected by the method of artificial vagina, during the
insemination campaign. All ejaculates were diluted with a 6AG extender and
frozen by the Cassou’s sequin method. Sperm viability was determined by eosin
and nigrosine smears, and enzyme activity was examined spectrophotometrically.
As a result, the percentage of vital sperm after cryopreservation decreased by 15%
(P ≤ 0.001). The freezing and thawing process also reduced the activity of the
enzymes LDH, ALP, GOT / AST and GPT / ALP. In conclusion, the observed
enzymes, in relation to sperm vitality, could be used as indicators to optimize the
protocols for cryopreservation of ram’s sperm.

AB  - Considering the fact that sheep production has an important role
in agriculture of Serbia, lamb performance is essential. Objective of the study was
to investigate effect of year, lambing season, sex and birth type on growth
performances in lambs of MIS breed. Animal data (birth date, birth type, sex, birth
weight -BW0, body weight after 30 days - BW30 and body weight after 90 days –
BW90) are gained from control of productive parameters maintained from 2011 to
2020. Research was conducted on the sample of 1592 lambs. Average daily gain
from birth to 30 days (ADG1), from 30 to 90 days (ADG2), and from birth until 90
days (ADG3), were calculated and included in analysis. Calendar year was divided
in four seasons, each season consists from 3 months: winter, spring, summer and
autumn. Average body weights (± standard deviation) at birth, after 30 and 90 days
were 4.41 kg (± 0.99), 14.11 kg (± 2.80), 24.05 kg (± 3.86), respectively. Average
daily gains were 319.87 g (± 74.97), 164.98 g (± 35.39) and 216.88 g (± 36.86) for
ADG1, ADG2 and ADG3, respectively. Lambing type and sex of the lambs
affected all of the observed traits very significantly (p < 0.01). Lambing year had
very significant effect (p < 0.01) on BW30, on ADG1 and ADG2, while lambing
season significantly (p < 0.05) affected BW90, ADG2 and ADG3.Based on the
results it can be concluded that birth type and sex had strongest effects in early
productive parameters of lambs.
AB  - S obzirom na to da ovčarstvo ima važnu ulogu u poljoprivredi Srbije,
produktivnost jagnjadi je od izuzetnog značaja. Cilj istraživanja je bio da se ispita
uticaj godine, sezone jagnjenja, pola i tipa rođenja na produktivne parametre
jagnjadi MIS rase. Podaci o životinjama (datum rođenja, tip rođenja, pol, telesna
masa na rođenju -BW0, telesna masa posle 30 dana - BW30 i telesna masa nakon
90 dana - BW90) su dobijeni kontrolom proizvodnih parametara održanih od 2011.
do 2020. godine, na uzorku od 1592 jagnjadi. Prosečan dnevni prirast od rođenja
do 30 dana (ADG1), od 30 do 90 dana (ADG2), i od rođenja do 90 dana (ADG3),
izračunat je i uključen u analizu. Kalendarska godina je podeljena na četiri godišnja
doba (zima, proleće, leto i jesen), a svako godišnje doba sastoji se od 3 meseca.
Prosečna telesna masa (± standardna devijacija) pri rođenju, posle 30 i 90 dana bila
je 4,41 kg (± 0,99), 14,11 kg (± 2,80), 24,05 kg (± 3,86), redom. Prosečni dnevni
prirasti iznosili su 319,87 g (± 74,97), 164,98 g (± 35,39) i 216,88 g (± 36,86) za
ADG1, ADG2 i ADG3, redom. Tip rođenja i pol jagnjadi značajno su uticali na sve
ispitivane osobine (p < 0,01). Godina rođenja imala je veoma značajan uticaj (p <
0,01) na BW30, na ADG1 i ADG2, dok je sezona jagnjenja značajno (p < 0,05) uticala na BW90, ADG2 i ADG3. Na osnovu rezultata može se zaključiti da su tip i
pol rođenja imali najjače efekti u ranim produktivnim parametrima jagnjadi.

productive parameters of lambs., S obzirom na to da ovčarstvo ima važnu ulogu u poljoprivredi Srbije,
produktivnost jagnjadi je od izuzetnog značaja. Cilj istraživanja je bio da se ispita
uticaj godine, sezone jagnjenja, pola i tipa rođenja na produktivne parametre
jagnjadi MIS rase. Podaci o životinjama (datum rođenja, tip rođenja, pol, telesna
masa na rođenju -BW0, telesna masa posle 30 dana - BW30 i telesna masa nakon
90 dana - BW90) su dobijeni kontrolom proizvodnih parametara održanih od 2011.
do 2020. godine, na uzorku od 1592 jagnjadi. Prosečan dnevni prirast od rođenja
do 30 dana (ADG1), od 30 do 90 dana (ADG2), i od rođenja do 90 dana (ADG3),
izračunat je i uključen u analizu. Kalendarska godina je podeljena na četiri godišnja
doba (zima, proleće, leto i jesen), a svako godišnje doba sastoji se od 3 meseca.
Prosečna telesna masa (± standardna devijacija) pri rođenju, posle 30 i 90 dana bila
je 4,41 kg (± 0,99), 14,11 kg (± 2,80), 24,05 kg (± 3,86), redom. Prosečni dnevni
prirasti iznosili su 319,87 g (± 74,97), 164,98 g (± 35,39) i 216,88 g (± 36,86) za
ADG1, ADG2 i ADG3, redom. Tip rođenja i pol jagnjadi značajno su uticali na sve
ispitivane osobine (p < 0,01). Godina rođenja imala je veoma značajan uticaj (p <
0,01) na BW30, na ADG1 i ADG2, dok je sezona jagnjenja značajno (p < 0,05) uticala na BW90, ADG2 i ADG3. Na osnovu rezultata može se zaključiti da su tip i
pol rođenja imali najjače efekti u ranim produktivnim parametrima jagnjadi.",

AB  - The aim of the present study was to determine a possible relationship between sperm
parameters and activity of creatinine kinase (CK) in the process of cryopreservation.
To achieve this goal, 14 ejaculates of 7 rams of the breed Ile de France, aged 3-5
years, were examined. The rams were breeding under the same conditions of feeding,
growing and sexual use. Ejaculates were obtained via the artificial vagina method
and were diluted 1:12 with 6 A-G extender. The resulting ejaculates were examined
by a computer assisted semen analysis (CASA) to determine total motility, velocity
parameters, and morphological status. The intracellular and extracellular activity of
CK were determined spectrophotometrically. After sperm evaluation, the ejaculates
were frozen using Cassou sequin technology and the same parameters were analyzed
after thawing the samples. From the obtained results we found a 26% decrease in
sperm motility after thawing. The velocity parameters for VCL, VSL, VAP, AHL and
BCF also decreased significantly after thawing (P≤0.01), but an increase was found
in the linear velocity parameters - LIN, STR and WOB (P≤0.01). Cryopreservation
also increased the percentage of abnormal sperm by 17%. A higher intracellular CK
activity, which decreased significantly after freeze-thawing (P≤0.001) was measured.
In conclusion, cryopreservation decreased sperm motility and increased the percentage
of abnormal sperm (mostly with tail damage), but we did not establish a relationship
between linear the velocity parameters LIN, STR and WOB, sperm morphological
status and CK activity. Therefore, CK activity cannot serve as an indicator of sperm
quality in the process of cryopreservation.

AB  - This paper describes the present state of goat production in
Central Serbia, discussing the challenges and future prospects for this livestock
system. Number of goats in the country is decreasing and it has been so throughout
the years now. Production systems in goat sector in Serbia are predominately
extensive or semi-intensive, especially in hilly-mountainous areas and goats are
kept in small herds. The majority of goats raised in Central Serbia region are of
French Alpine breed, which takes the most dominant place in breed structure. In
addition to French Alpine breed, there are also Saanen, Balkan and Domestic white
goats. Production of goats in Serbia is directed towards milk-meat, but primarily
milk and there are no typical meat (fattening) breeds of goats in Serbia. In Central
Serbia, herd books are kept for goats raised on this territory. Quality breeding
animals are registered at Central herd book and are under productivity control.
However, this is only a small portion of animals and the productivity of majority of
goats is unknown. Productivity of high yielding breeds such as Alpine and Saanen
goat is inconsistent and not high, especially milk production. Indigenous goat
breeds are considered endangered and their breeding was almost completely
abandoned. Goat sector in Central Serbia is almost completely dependent on
government founding. The only sustainable prospects for preserving goat sector in
Central Serbia for the future are clean organic production, reinforcement of
markets for goat products and smart government founding.

AB  - Pirot breed is a highly endangered autochthonous population of
sheep in Serbia, from which several important national brands originate: Pirot
lamb, Pirot carpet and Pirot hard cheese. In the available literature, there are no
data on hematological and biochemical parameters of the blood of this population.
The aim of this paper, which represents the beginning of the research, is to
determine the above indicators in the blood of Pirot Pramenka, which will
contribute to the preservation of this population. Since the breed affects the value
of blood parameters, the obtained results will be used to define reference intervals
for this population and compare with others. The study included 30 clinically
healthy sheep, 2-3 years old, from the area of Stara Planina. Blood samples were
taken by puncture to c. jugularis from which, after coagulation and centrifugation,
blood serum was extracted. Haematological analyzes were performed in the next
24 hours on a Siemens Advia 120 analyzer. The following parameters were
determined: total number of leukocytes, erythrocytes, platelets, hemoglobin
content, hematocrit value, MCV, MCH, PLT and MPV. Biochemical blood tests
were performed using Olympus AU 400 analyzers.The following parameters were
determined: total protein, albumin, globulin, urea, creatinine, glucose, total
bilirubin, cholesterol. Also, the following minerals were determined - calcium,
phosphate and magnesium, and following enzymes: AST, GGT and CK.
Descriptive statistical analysis was performed using the statistical package
STATISTICA (Version 8). Hematological indicators of Pirot pramenka are in
reference intervals for sheep, which indicates good animal health status.
Biochemical parameters of Pirot pramenka blood were within defined
physiological limits, except for creatinine and phosphorus levels, which were
below the lower limit, which is a consequence of dehydration and reduced
alimentary intake. In accordance with the obtained results, it is necessary to correct
the diet.

AB  - Success in lamb production depends on their body weight, and
in recent years there had been a growing interest in understanding the impact of
some factors such as parity on sheep productivity. Knowing the factors that affect
the development and growth of lambs can help make changes in breeding plans.
This paper was to detect important factors affecting lamb's birth weight which
usually are not taken to consideration and have substantial part planning
improvement in sheep production. Miss breed sheep were cross or pair with Ile de
France rams three times, with the following characteristics observed; Body weights
of lambs at birth, type of birth, number of lambs born per sheep per parity in the
periods from 2018 to 2020. The result of each lambing per parity of each ewe was
the basis of the study. The ANOVA, general linear model, univariate analysis of
variance, and descriptive statistics derived to assess the following effects: Effect of
parity on lambs’ birth weight; Effect of parity on birth type, and lambs birth
weight; Interaction effect of different subject effects on birth weight; The
total marginal means of lambing rate per dam in three parities.
The result obtained showed a very significant influence of the indicated factors on
tested traits (P<0.01). Based on the results of our research, we can conclude that
parities have a very significant impact, so they need more attention in the future.

AB  - Due to the political, demographic and economic situation,
agriculture in Serbia changed, including also the structure in sheep breeds.
Traditional sheep breeding centers with large pasture areas and large number of
local breeds and strains are deserted, and, consequently, sheep production focused
on meat production, in intensive systems, but in expensive and inadequate ways.
This led to decreasing number in local breeds (pramenka) with its strains. In this
research, two most numerous pramenka strains were observed, Sjenica and Svrljig
strains, concerning their number, productive and reproductive parameters.
Population of registered and active heads in 2020. was 139,319 for Sjenica and
19585 for Svrljig strain. Weight on birth for Sjenica and Svrljig lambs were 3.20
and 3.15, while weight after 30 days and on weaning was 11.06, 11.42 and 27.02
and 24.97, respectively. Lambing index was 1.27 for Sjenica and 1.29 for Svrljig
strain. Svrljig strain had longer lactation (104 vs. 88 days), with higher milk
production (64.05 kg vs. 55.01 kg), but protein content was higher in Sjenica
sheep’s milk (5.08% vs. 4.19%). Besides their importance on agro-biodiversity and
genetic pool, these strains are best adapted for breeding conditions that are in hilly
and mountainous parts of Serbia. As triple production strains, their milk, meat and
wool could be used in processing to traditional, high-quality products with
additional value, so can provide extra income for the farmers which leads to

abstract = "Due to the political, demographic and economic situation,
agriculture in Serbia changed, including also the structure in sheep breeds.
Traditional sheep breeding centers with large pasture areas and large number of
local breeds and strains are deserted, and, consequently, sheep production focused
on meat production, in intensive systems, but in expensive and inadequate ways.
This led to decreasing number in local breeds (pramenka) with its strains. In this
research, two most numerous pramenka strains were observed, Sjenica and Svrljig
strains, concerning their number, productive and reproductive parameters.
Population of registered and active heads in 2020. was 139,319 for Sjenica and
19585 for Svrljig strain. Weight on birth for Sjenica and Svrljig lambs were 3.20
and 3.15, while weight after 30 days and on weaning was 11.06, 11.42 and 27.02
and 24.97, respectively. Lambing index was 1.27 for Sjenica and 1.29 for Svrljig
strain. Svrljig strain had longer lactation (104 vs. 88 days), with higher milk
production (64.05 kg vs. 55.01 kg), but protein content was higher in Sjenica
sheep’s milk (5.08% vs. 4.19%). Besides their importance on agro-biodiversity and
genetic pool, these strains are best adapted for breeding conditions that are in hilly
and mountainous parts of Serbia. As triple production strains, their milk, meat and
wool could be used in processing to traditional, high-quality products with
additional value, so can provide extra income for the farmers which leads to
survival and sustainable development of rural areas.",

AB  - Sodium chloride (NaCl) is one of the most important food additives and it has a significant impact on the sensory and microbiological properties of meat products. According to the Regulation on the quality of ground meat, meat preparations and meat products (Official Gazette of RS 50/2019), the salt content in meat products is not defined. The average NaCl values in these products can be concluded by comparison with available experimental and literature data. The aim of this study was to examine the content of sodium chloride in different meat products from 3 different production batches locally produced. A total of 42 samples were tested: Kulen and Čajna sausage (fermented sausages), dry tenderloin (cured meat products), smoked tenderloin (smoked products), hot dog (finely chopped boiled sausage), Serbian sausage (coarsely chopped boiled sausage) and pancetta (bacon). The highest average sodium chloride content was found in dry tenderloin (4.49g/100 g) while the lowest content was measured in hot dogs (1.88g/100 g). Comparing the obtained values of sodium chloride content with the values obtained by other authors for fermented products (Kulen and Čajna sausage), the tested products had significantly higher values of salt content, while the lowest average content of sodium chloride was found in smoked tenderloin samples. For other products, the content of the tested parameter was similar to the values reported in the literature. After the analysis of available samples, it was determined that the manufacturer adhered to the prescribed amounts of NaCl, according to the recipe, in every product. There weren't any notable deviations in the preparation of monitored meat products.

AB  - Inbreeding seems to be a useful tool to improve the 
population by increasing the frequency of desirable genes, but the first result of 
inbreeding is inbreeding depression. Inbreeding depression implies the 
reduction of additive genetic variance and phenotypic values for efficiency 
traits in inbred animals. The kinship degree is measured by the inbreeding 
coefficient and expressed in percentage (%) from 0 to 100, that as the 
percentage higher, the higher the kinship. Nevertheless, one thing is for sure, 
practice in sheep breeding has shown that the use of inbreeding causes 
undesirable consequences like reduction of body shape or abnormal 
development, developmental delay, resistance to external influences and 
diseases, poor fertility or infertility, metabolic disorders, negative 
characteristics in fattening, albinism and the appearance of degenerative 
traits, loss of instinct, psychophysical defects and so on. Inbreeding is an 
inevitable companion of livestock production. No matter how hard we try to 
avoid it, in practice, it is almost impossible. It could not completely eliminate, 
but with proper breeding and selection management, it can be kept under 
control.

AB  - The strategy of conservation of endangered sheep populations
implies morphological and genetic characterization, as basic preconditions for their
conservation. The aim of this study was to determine the morphometric
characteristics, their correlations and the index of physical development of Pirot
pramenka, which has the status of the most endangered population in Serbia. The
measuring was performed on 30 sheep, aged 3 years, reared in the area of Stara
Planina. The descriptive statistical procedure was performed using the statistical
package Statistica (version 8). The average height at the withers was 56.31 cm,
body length 62.93 cm, chest width 18.37 cm, chest depth 25.96 cm, chest
circumference 77.59 cm, shin circumference 6.70 cm. The strongest and
significantly positive correlation (P <0.05) was found between chest depth and
height at withers (0.65), body length (0.58) and body weight (0.56). Pirotska
pramenka has slightly higher indices of format, chest and massiveness, in relation
to breeds Vitoroga Žuja and Travnik Pramenka. These morphometric traits suggest
that, compared to previous research, the body frame of Pirot pramenka sheep did
not change significantly, which means that there were no crosses with other breeds
due to geographical isolation and enthusiasm of breeders to preserve the
indigenous Pirot pramenka which was the starting point for following authentic
brands: Pirot lamb, cheese and carpet. Hence the biological and moral imperative:
to preserve this highly endangered population.

AB  - The drive to mate females is variable among the rams and can have a major impact on sheep production. Androgen testosterone
may be a key mediator within the expression of various morphological and behavioural traits in mammals, but the factors underlying
individual variation in circulating testosterone levels are poorly understood.
The aim of this study was to investigate the development of sexual behaviour patterns in ram lambs as well as the role of testosterone
in the expression of their libido.
Research was carried out on the sheep farm of the Institute for Animal Husbandry, Belgrade, Serbia. The study included 20 crossbred
ram lambs (autochthonous breed Pirot Pramenka x Merinolandschaf x Ile de France). All ram lambs used in the study were
of same age and rearing conditions. They were weaned at 2 months of age and kept indoors from birth throughout the whole
study. Animals were introduced in the study at the age of 3 months and the trial was completed at the rams’ age of 17 months.
Blood samples for testosterone levels were taken bimonthly (at the age of 3, 5, 7, 9, 11, 13, 15 and 17 months), as well as were
male-female and male-male interactions recorded.
Male-female interactions included the following elements of behaviour: nosing (or anogenital sniffing), pawing, flehmen response,
attempted mounts. Also, duration of all male activities directed towards ewe was recorded (male-female interactions in total).
Male-male interactions involved the frequency of male-male mounts.
Performed investigations showed that sexual behaviour of rams was age dependent, but poorly correlated to serum testosterone.
The average serum testosterone levels ranged from 1.83-13.28 ng/mL, and were age dependant (P<0.05).
Male-female oriented behaviour developed linearly with age, while male-male specific behaviour was characterized by high intensity
in young age and then pronounced variability in later test periods. None of the studied behavioural interactions were highly
correlated to serum testosterone. These findings support standpoint of more than one factor influencing development of sexual
behaviour of ram lambs.

abstract = "The drive to mate females is variable among the rams and can have a major impact on sheep production. Androgen testosterone
may be a key mediator within the expression of various morphological and behavioural traits in mammals, but the factors underlying
individual variation in circulating testosterone levels are poorly understood.
The aim of this study was to investigate the development of sexual behaviour patterns in ram lambs as well as the role of testosterone
in the expression of their libido.
Research was carried out on the sheep farm of the Institute for Animal Husbandry, Belgrade, Serbia. The study included 20 crossbred
ram lambs (autochthonous breed Pirot Pramenka x Merinolandschaf x Ile de France). All ram lambs used in the study were
of same age and rearing conditions. They were weaned at 2 months of age and kept indoors from birth throughout the whole
study. Animals were introduced in the study at the age of 3 months and the trial was completed at the rams’ age of 17 months.
Blood samples for testosterone levels were taken bimonthly (at the age of 3, 5, 7, 9, 11, 13, 15 and 17 months), as well as were
male-female and male-male interactions recorded.

AB  - The main farmers goal is breeding of pure sheep breed outside the kinship. That way they want to preserve and improve qualities of the breed, such as high production of meat, milk or wool, strong construction, high fertility, length of productive life, health, etc. It is a challenge for breeders because it represents a management planning balance between homozygosity and heterozygosity. Breeding sheep in a purebred requires a certain level  of genetically predictable homozygosity to promote desirable traits. Balancing is appropriate to avoid inbreeding depression. A particular problem arises in small populations, which have only hope in the line breeding system. This review paper discusses iptions to overcome this situation.

AB  - In addition to nutritional value, a very important criterion for the selection of meat, for the modern consumer is the health aspect, i.e. the content of fat and the profile of fatty acids in meat. The content of fat and fatty acids, among other things, is conditioned by the feeding system and the rearing method. Lambs fed on pasture have a lower share of fat in the carcass than animals fed with a concentrated mixture, in a closed system. The recommended value for the ratio of polyunsaturated to saturated fatty acids is up to 0.45, and below 4.0 for the n-6 and n-3 fatty acids ratio. Taking into account that the influence of lamb nutrition on these relationships is significant, modelling of fatty acid composition should be directed to the lamb nutrition system which leads to a decrease in the content of saturated and an increase in the concentration of polyunsaturated (PUFA) fatty acids in meat. A feeding strategy involving a grazing feeding system of lambs results in a higher content of n-3 PUFA, CLA and a more favourable n-6/n-3 ratio of fatty acids, while the lamb meat originating from animals fed concentrated diets has a higher proportion of n-6 PUFA and a higher n-6 ratio/n-3 fatty acids, which exceeds the recommended value of 4.0. Conjugated linoleic acid (CLA) is of great importance since it has an anticancer, antidiabetic effect as well as an effect on the immune system, suggesting a direction for future research on lamb meat.
