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  - This study analyses the effect of different protein levels in broiler feeds (supplemented with protease) and different lengths of fattening period on some parameters related to dressed carcass quality. Medium-growing Master Gris broiler chickens were used in a fattening trial lasting 63 days. At slaughter, dressing percentages and abdominal fat percentages were determined based on traditionally dressed carcass weights and abdominal fat weights of broilers at 49 and 63 days, and conformation indices were calculated based on absolute conformation measurements. Results showed that dietary treatment had an effect only on one relative conformation measurement - body weight/shank length in chickens at 49 days, as control broilers had higher values of this index compared to chickens receiving feeds containing reduced levels of crude protein and protease supplementation (0.2% or 0.3%). Length of fattening period affected almost all studied parameters, except breast angle, dressing percentage of traditionally dressed carcass and abdominal fat percentage.

Rezultati ogleda su pokazali da je uticaj ispitivanih obroka ispoljio efekat samo na jednu relativnu meru konformacije trupova - telesna masa/dužina piska kod pilića starosti 49.dana, jer su pilići iz kontrolne grupe imali veću vrednost ovog indeksa u odnosu na piliće koji su hranjeni smešama sa nižim nivoima sirovih proteina, uz dodatak enzima proteaze (0,2% ili 0,3%). Različita dužina trajanja tova uticala je na skoro sve ispitivane parametre, izuzev na veličinu grudnog ugla, randman klasično obrađenog trupa i udeo abdominalne masti.

AB  - The objective of the present study was to investigate nutritional and metabolic status in Simmental cows during early and mid-lactation. Fifteen early lactating cows and 15 mid lactating cows were chosen for the investigation. Blood samples were collected to measure beta-hydroxybutyrate (BHB), nonesterified fatty acids (NEFA), triglycerides (TG), glucose and the activity of aspartate transaminase (AST). Early lactation as compared to mid lactating cows were found to have significantly higher (P (lt) 0.05) blood serum concentrations of NEFA, BHB and AST and lower blood serum concentrations of glucose (P (lt) 0.05) and TG (P>0.05). Significantly negative correlations were observed between BHB and glucose (P (lt) 0.01), BHB and TG (P (lt) 0.05), NEFA and glucose (P (lt) 0.05). Significantly positive correlations were observed between NEFA and BHB (P (lt) 0.05), NEFA and AST (P (lt) 0.05), glucose and TG (P (lt) 0.01). The results suggest that these parameters can serve as useful indicators of the nutritional and metabolic status of dairy cows during lactation.

Uzorci krvi su uzeti i merene su vrednosti za beta-hidroksi-buternu kiselinu (BHB), slobodne masne kiseline (NEFA), trigliceride (TG), glukozu i aktivnosti aspartat-amino transaminaze (AST). Krave na početku laktacije su imale statistički značajno veće koncentracije (P (lt) 0.05) NEFA, BHB i AST u krvi i značajno niže vrednosti za glukozu i trigliceride (P (lt) 0.05). Statistički značajne negativne korelacije su utvrđene između vrednosti BHB i glukoze (P (lt) 0.01), BHB i TG (P (lt) 0.05), NEFA i glukoze (P (lt) 0.05).

AB  - This study examined the activities of aspartate-aminotransferase (AST), gamma-glutamyl-transferase (GGT) and lactate-dehydrogenase (LDH) in the blood serum of 45 dairy Simmental cows divided into three groups according to production period. The first group (n=15) consisted of late pregnant dairy cows, the second group (n=15) cows in the early lactation, and the third group (n=15) cow in mid lactation. The significant higher activity (P (lt) 0.05) of AST, GGT and LDH were determined in the early lactation period than in dry period and during full lactation. Research results showed possibility of mild degree of hepatic lesions, probably due to fat infiltration in early lactation cows. Serum AST enzyme activities were significant correlated (P (lt) 0.05) with GGT and LDH activities and may be most sensitive indicator.
AB  - U ovom radu je određivana aktivnost aspartat-aminotransferaze (AST), gama-glutamat-transferaze (GGT) i laktat dehidrogenaze (LDH) u krvnom serumu kod 45 simentalskih mlečnih krava, podeljenih u tri grupe u zavisnosti od produktivnog perioda. Prvu grupu (n=15) su činile visoko gravidne krave, drugu grupu (n=15) krave u ranoj laktaciji, a treću grupu (n=15) krave tokom pune laktacije. Statistički značajno veće aktivnosti AST (P (lt) 0.05),GGT (P (lt) 0.05) i LDH (P (lt) 0.05) u krvnom serumu su utvrđene kod krava u ranoj laktaciji u odnosu na aktivnosti ovih enzima u serumu kod zasušenih krava i krava u punoj laktaciji. Dobijeni rezultati ukazuju na mogućnost blagog stepena oštećenja ćelija jetre, odnosno masnu infiltraciju hepatocita kod krava na početku laktacije. Serumske aktivnosti AST su bile u značajnoj korelaciji (P (lt) 0.05) sa aktivnostima GGT i LDH u krvnom serumu pa se AST može smatrati pouzdanim indikatorom u tvrđivanju funkcionalnog stanja jetre kod mlečnih krava tokom peripartalnog perioda i pune laktacije.

Dobijeni rezultati ukazuju na mogućnost blagog stepena oštećenja ćelija jetre, odnosno masnu infiltraciju hepatocita kod krava na početku laktacije. Serumske aktivnosti AST su bile u značajnoj korelaciji (P (lt) 0.05) sa aktivnostima GGT i LDH u krvnom serumu pa se AST može smatrati pouzdanim indikatorom u tvrđivanju funkcionalnog stanja jetre kod mlečnih krava tokom peripartalnog perioda i pune laktacije.",

AB  - The effect of systematic and continuous environmental factors on milk performance traits over standard lactations in 2805 Simmental cows was evaluated using the general linear model. The systematic factors included the effect of farm or breeding area, calving season, year of birth, season of birth, lactation group and their interactions. The continuous factor analysed was the effect of age at first conception. The effect of farm, lactation group and calving season on standard lactation milk performance was found to be highly significant (P (lt) 0.01), excepting the effect of calving season on milk fat percent in standard lactations which showed statistical significance (P (lt) 0.05). The interactions between year and season of birth, farm and calving season, and farm and lactation group had a highly significant effect (P (lt) 0.01) on all performance traits studied. Age at first conception, as a continuous factor, had a highly significant effect (P (lt) 0.01) on milk yield and milk fat percent, and a non-significant effect on milk fat yield. The model used to correct the performance traits over standard lactations for the effect of systematic factors was highly significant (P (lt) 0.01). The variance of the model accounted for 20.06 and 37.31% of the total variance of milk fat yield and milk fat percent, respectively. The resulting coefficients of determination (R-2) ranged from 0.20 for milk fat yield to 0.37 for milk fat percent.

AB  - In this paper, the results of fattening and meat characteristics of lambs of the new breed of sheep in Serbia, called Mis sheep, are presented. Mis breed as a meaty type of sheep, has been developed for the past 20 years at the Institute of Animal Husbandry, Belgrade-Zemun. The total and daily gains in 1-30 days were of 7.5 kg and 250 g, and in 61-90 days the growth dynamics was even higher by 60% with the total gain of over 12 kg; the daily value exceeded 400 g. Food consumption, calculated in units of energy, was about 13.5 MJ with a slightly larger share of concentrate in the mass of gain of lambs. The dressing percentage of lambs at the age of three months was about 59%. In addition, the highest percentage of carcass meat was of the first category, followed by the meat of the second category and the lowest representation of the third category of meat. Muscle tissue had an absolute advantage over the other tissues and accounted for over 57%, followed by fat, bone and connective tissue, which accounted for the remaining 43% of the weight of three rib pattern. Mis sheep population, similar to the known foreign meat breeds, has a little more fat, which influences the better technological and sensory properties.

AB  - The large number of sheep, especially the ones that spend the majority of time on pastures, is been fed with the meals, which do not contain all the necessary mineral substances. The level of calcium, phosphorus and magnesium on natural pastures is too low in relation to the needs of sheep. Therefore, the irregularity in the feeding of sheep occurs because of the absence of the other food sources. These irregularities are in the range from the acute mineral deficit or illness to the mild temporary forms, which could hardly diagnose, but they affect the level of production. The content of calcium, phosphorus and magnesium in the blood serum of sheep, as one of the indicators of the supplementation of sheep with these substances, has given in this paper. The average level of calcium in the blood serum of the control group of sheep was 2.61 mmol/l, phosphorus 1.04mmol/l and magnesium 1.31 mmol/l of serum. In the blood serum of the tested group, the average contents of calcium was 2.33 mmol/l, phosphorus 0.92 mmol/l and magnesium 1.37 mmol/l.

AB  - Fifteen early-lactation cows and 15 mid-lactation cows were chosen for the analysis. Blood samples were collected to measure the beta-hydroxybutyrate (BHB), non-esterified fatty acids (NEFA), triglycerides (TG), glucose (Glu), total protein (TP), albumin (ALB), total bilirubin (TB), urea (U) and the activity of aspartate transaminase (AST) and gamma-glutamyl transferase (GGT). Earlyl-actation cows showed significantly higher (P (lt) 0.05) values of serum BHB and NEFA, and lower of (P (lt) 0.05) glycemia levels compared to mid-lactation cows. High lipomobilization (NEFA >0.4 mmol/l) and subclinical ketosis (BHB >1.2 mmol/L) were detected in 6 (40%) and 14 (94.4%) early-lactation cows, respectively, and in none of the mid lactation cows. AST activities above 100 IU/1 were detected in two early-lactation and none of the mid-lactation cows. TG concentrations below 0.12 mmol/l were found in 7 (44%) early-lactation and 2 (13.3%) mid-lactation cows. Glucose levels were below 2.5 mmol/l in 10 (66.6%) early-lactation and 5 (33.3%) mid-lactation cows. Early-lactation cows showed lower blood serum concentrations of TG (P>0.05), ALB (P>0.05), TP (P (lt) 0.05), U (P>0.05) and GTT (P>0.05) activities and higher concentrations of TB (P>0.05) and AST activities (P (lt) 0.05), as compared to mid-lactation cows. These metabolic characteristics were correlated with DMI and energy balance (EB). Blood serum values for glucose, TG, BHB, NEFA and AST showed that early-lactation cows suffered from metabolic disturbances, associated with ketosis, and some degree of hepatic lesions, probably due to fat infiltration. These serum parameters may have a key role in evaluating the metabolic status of dairy cows.

AB  - Investigations were carried out in order to determine whether the addition of bioactive substances 'Bioril' on different percentages in concentrate (0.3% and 0.6%), has an impact on weight gain and feed conversion in lambs. For the experiment were used lambs of Mis sheep breed, which at the beginning of the experiment were 50 days of age. The experiment lasted 42 days, so it is over when all lambs had 92 days of age. The experiment included 60 lambs (30 male and 30 female) were divided into three groups-20 lambs per group (control group I and II and III experimental groups ).The results shows that the greatest gains made lambs of group III. The difference between body weight of group I and II was 1.62 kg and was statistically significant (P (lt) 0.01). The difference between body weight of I and III group was 1.87 kg and was also statistically significant (P (lt) 0.01). The difference between the body weight of II and III groups was 0.25 kg and was not statistically significant (P>0.05). We find that lambs of all groups consumed per kg of gain more concentrated than hay. The difference in feed conversion between groups is not significant (P>0.05), but lambs of groups III and II consumed per unit of gain approximately 5g/kg and 10g/kg less concentrate than lambs of group I. Most hay consumed by lambs of group I. The difference in hay consumption between groups I and II is 20 g/kg. Lambs in group III consumed 30 g/kg which was less hay than group I and less 10 g/kg than lambs of group II. The most energy per kg of gain was consumed by lambs of group III, whereas lambs in II group consumed the least energy.

Za eksperiment su korišćena jagnjad od ovaca rase Mis, koja su na početku eksperimenta bila 50 dana starosti. Eksperiment je trajao 42 dana, tako da je završen kada su jagnjad imala 92 dana starosti. U eksperiment je uključeno 60 jagnjadi (30 muškog i 30 ženskog pola). Jagnjad su podeljena u tri grupe-20 jagnjadi po grupi (kontrolna grupa I i II i III eksperimentalne grupe). Rezultati pokazuju da su ostvareni najveći dnevni prirasti kod jagnjadi II eksperimentalne grupe. Razlika između telesne mase grupe I i II je 1.62 kg i bila je statistički značajna (P (lt) 0,01). Razlika između telesne mase I i III grupe je bila 1,87 kg i takođe je bila statistički značajna (P (lt) 0,01). Razlika između telesne mase II i III grupe je bila 0,25 kg i nije bila statistički značajna (P>0,05). Smatramo da je jagnjad svih grupa konzumirala po kg prirasta više koncentrata nego sena. Razlika u konverziji hrane između grupa nije značajna (P>0,05), ali jagnjad grupe III i II troši po jedinici prirasta oko 5g/kg i 10g/kg manje koncentrata nego jagnjad grupe I. Više sena troše jagnjad iz I grupe. Razlika u potrošnji sena između grupa I i II je 20g /kg. Najviše energije po kg prirasta troši jagnjad iz III grupe, dok jagnjad iz II grupe troši najmanje energije.

AB  - The effect of interaction between the farm and calving season, as well as the farm and group of lactations on milk performance traits (milk yield, yield of milk fat, 4% fat corrected milk and milk fat content) was analyzed on sample of 2805 Simmental cows with total 9718 standard lactations, housed on dairy farm 'Zlatiborski suvati' on Zlatibor (578 cows and 1968 lactations), dairy farm of the Agricultural holding Dobričevo in Ćuprija (964 cows and 3237 lactations) and dairy animals housed on family farms/households in the region of Kotraža (1263 cows and 4513 lactations). The significance of the effect of interaction between the farm and calving season, as well as interaction between the farm and group of lactations on all milk performance traits was very high (P (lt) 0.001), which justified their inclusion into models for assessment of the breeding value of dairy cows. The share of variance of interactions in total variance of milk performance traits in standard lactations was low (below and around 4%), which clearly indicated even more systematic factors and their interactions which influence the total variability of observed traits of milk performance of cows in standard lactations.

AB  - Milk yield and milk chemical composition are largely affected by the quality of dairy cattle diet. The chemical composition of milk is dependent upon a large number of factors, including breed, diet, care, housing system, stage of lactation, etc. Milk composition is primarily a breed-specific trait. This study was conducted over a period of 15 months, involving Serbian Spotted dairy cattle. The experimental animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental Groups I and II were fed compound feeds supplemented with 4% and 2% zeolite, respectively. Milk samples were analysed for the contents of milk fat, proteins, fat-free solids and lactose, and density. The results obtained suggest that zeolite supplementation affects milk chemical composition, depending on the zeolite level present in livestock feed.
AB  - Najveći sadržaj mlečne masti u mleku je izmeren kod krava I-O grupe 4,62%, zatim kod K-grupe 4,28% i najmanji kod II-O grupe 4,26%. Statistički signifikantnih razlika u sadržaju mlečne masti među grupama je bilo (P (lt) 0,05). Nivo proteina u mleku krava bio je u intervalu od 3,34% kod krava II-O grupe do 3,51% kod krava kontrolne grupe.

Na osnovu sadržaja proteina u mleku statistički značajnih razlika između grupa nije bilo (P>0,05). Prosečne vrednosti gustine mleka bile su u opsegu od 31,21% kod krava IIO grupe do 33,00% kod krava K-grupe. Kao i kod prethodne osobine i ovde je najmanja prosečna vrednost merene osobine bila kod krava II-O grupe (31,21), sa isto tako, najmanjim koeficijentom varijacije među grupama (3,01). Kod ove osobine uočene su statistički značajne razlike među grupama (P (lt) 0,05). Najveći sadržaj SMBM u mleku imale su krave K-grupe sa iznosom od 9,56%, a najmanju krave II-O grupe 9,11%. Najveće variranje ove osobine je kod krava K-grupe, a najmanje kod krava I-O grupe sa iznosom od 2,51%. Sadržaj SMBM u mleku pokazao je statistički značajne razlike (P (lt) 0,05). Sadržaj laktoze u mleku krava bio je u intervalu od 5,01% kod krava II-O grupe do 5,26% kod krava K-grupe. Krave I-O grupe imale su količinu laktoze koja se nalazila između ove dve grupe. Sadržaj laktoze u mleku krava između grupa pokazao je statistički značajne razlike (P (lt) 0,05). Dodavanje zeolita ('Tufozel') imalo je uticaja na hemijski sastav mleka kod ispitivanih krava muzara.
