AB  - The body weight of calves in the earliest period of their life (age from 0 to 7 days) is under the greatest influence of the farm and the season of birth. The farm manifests its influence most often through the conditions of nutrition and housing and the organization of the technological production process, while the influence of the birth season is manifested through microclimatic and nutritional conditions, as well. The most common deficiencies related to the nutrition of newborn calves are related to: inadequate colostrum supply in terms of quality, quantity and time of colostrum intake, which is closely related to the organization of the technological production process on the farm. Dietary deficiencies affect the body weight of calves at birth and at 8 days of age. In a study conducted over a year (4 seasons), the colostrum diet of newborn calves of the HF breed on two farms (A and B) with a tied housing system was analyzed. Calves were fed colostrum on both farms at intervals, usually up to 2 hours, less often up to 4 hours after birth. The colostrum consumed came from the mother, most often, and less often from the other cow, while on one of the farms it was also used frozen. However, the amount of colostrum consumed was deficient, it was 1-2 l on farm A, and 2.5 to 3 l on farm B. The occurence of a deficient diet or other deficiencies in the diet of calves was indicated by the average body weight, measured at birth and at the age of 8 days. On farm A, a lower average body weight of calves (37.95 and 39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories, respectively. The average body weight of calves was statistically significantly (p  lt 0.01) influenced by the farm and the season of birth, as well as their mutual interaction, but the effect of the farm was more pronounced.
AB  - Telesna masa teladi u najranijem periodu života teladi (uzrast od 0 do 7 dana) je pod najvećim uticajem farme i sezone rođenja. Farma svoj uticaj ispoljava najčešće kroz uslove ishrane i držanja i organizaciju tehnološkog procesa proizvodnje, dok se uticaj sezone rođenja ispoljava kroz mikroklimatske i uslove ishrane, takođe. Najčešći nedostaci vezani za ishranu novorođene teladi odnose se na: neadekvatno napajanje kolostrumom u smislu kvaliteta, količine i vremena uzimanja kolostruma, što je u tesnoj vezi sa organizacijom tehnološkog procesa proizodnje na farmi. Nedostaci u ishrani odražavaju se na telesnu masu teladi na rođenju i sa 8 dana života. U ispitivanju sprovedenom tokom 2013-2014 godine (4 sezone) analizirana je ishrana kolostrumom novorođenimh teladi HF rase na dve farme (A i B) sa vezanim sistemom držanja. Telad su napajana kolostrumom na obe farme u intervalu, najčešće do 2 sata, ređe do 4 sata nakon rođenja. Konzumirani kolostrum je poticao od majke, najčešće, a ređe od druge krave, dok se na jednoj od farmi koristio i zamrznut. Međutim, količina konzumiranog kolostruma bila je deficitarna, iznosila je 1-2 l na farmi A, a 2,5 do 3 l na farmi B. Na postojanje deficitarne ishrane ili drugih propusta u ishrani teladi ukazivala je prosečna telesna masa, merena na rođenju i u uzrastu od 8 dana života. Na farmi A je zabeležena manja prosečna telesna masa teladi (37,95 i 39,68kg) nego na farmi B (40,00 i 41,80kg) po starosnim kategorijama, redom. Na prosečnu telesnu masu teladi statistički veoma značajno (p lt 0,01) su uticali farma i sezona rođenja, kao i njihova međusobna interakcija, ali je efekat farme bio izraženiji.

AB  - This research was conducted with the aim of estimating genetic trend for a functional length of productive life (FLPL) in the population of Black and White cattle in Serbia. Research and bulls genetic evaluation for functional longevity were performed on a set of data provided by Agricultural Corporation Belgrade AD (PKB) which contained data on longevity and origin of 22109 cows out of which 26% records were right-censored. Functional length of productive life (FPLP) represents a time period from the first calving to culling or censoring corrected for milk production. Breeding values were estimated using Weibull method of proportional risks within survival analysis a genetic trend for FLPL was calculated using of a regression analysis. The cows included in the analysis were on average first calved in the age of 809 days and had an average share of 81.9% genes of Holstein Friesian breed. An average length of productive life was 1267 days (41.6 months). Distribution of bull standardised breeding values did not statistically significantly differ from normal distribution. An average standardised breeding value was 99. A slightly positive genetic trend was determined, that is, the length of functional productive life was by selection increased by 0.021 day at an annual level while a reliability of estimated breeding values showed a negative trend.

AB  - Three farms of dairy cows (A, B and C) were observed for health disorders of dairy cows and suckling calves. Farm A is farm with tied system of rearing, with 1100 cows, while farms B and C have 400 and 600 cows kept loose with outdoor pens, respectively. Data regarding welfare criteria of dairy cows (health, feeding, housing and behaviour) were collected and analysed through Protocol of Welfare Quality (2009). Health disorders of dairy cows and suckling calves were collected and statistically analysed by chi-square test (X2 test). Welfare of all of three dairy farms were assessed as acceptable, meaning that provided welfare conditions meet the minimum requirements of animals. Principle of provision of good health was rated as acceptable (≥20 points) on farm A, while on farms with loose system (B and C) overall health rated as excellent (≥80 points). Occurrence rate of reproductive, locomotor, skin and claws disorders and digestive and systemic disorders of dairy cows and calves up to 4 months old were very different between three farms (A, B, C) with X2-values of 2901.71, 252.02, 204.08, 1152.31 and 184.23 respectively; α lt 0.01). According presented data, it is obvious that the majority health problems were observed in tied system of rearing, on farm A, such as reproductive disorders and mastitis, as well as injuries and bad body score and lame cows. The most serious health problems of the calves were diarrhea and bronchopneumonia of different etiology.

Traits of economic interest include milk protein genetic variants, milk production, disease and stress resistance etc.
AB  - U poslednjim decenijama dvadesetog veka, primenom metoda molekularne genetike omogućena je identifikacija gena koji utiču na variranje kvantitativnih osobina, kao i selekcija vezana za markere (MAS) koja se koristi za mapiranje genoma i procenu vezanosti gena koji utiču na ekonomski važne osobine domaćih životinja. Ovim metodama omogućeno je da se otkriju i potvrde genetske varijante proteina mleka, utvrdi otpornost organizma na bolesti i stres, odredi kvalitet mesa, izvrši determinacija pedigrea i pola utvrdi biodiverzitet i filogenetski stadijum organizma i dr. Primenom DNK testova metodom lančanog umnožavanja DNK (PCR) i PCRRFLP metodom koja se zasniva na polimorfizmu restrikcionih fragmenata u mogućnosti smo da identifikujemo varijante gena koji su odgovorni za varijabilnost kvantitativnih i drugih osobina koje želimo da unapredimo selekcijom. Selekciju, koja se bazira na ovim metodama, neophodno je uključiti u već tradicionalne odgajivačke programe kako bi se efekat selekcije i ekonomska vrednost stočarske proizvodnje povećala.

Primenom DNK testova metodom lančanog umnožavanja DNK (PCR) i PCRRFLP metodom koja se zasniva na polimorfizmu restrikcionih fragmenata u mogućnosti smo da identifikujemo varijante gena koji su odgovorni za varijabilnost kvantitativnih i drugih osobina koje želimo da unapredimo selekcijom. Selekciju, koja se bazira na ovim metodama, neophodno je uključiti u već tradicionalne odgajivačke programe kako bi se efekat selekcije i ekonomska vrednost stočarske proizvodnje povećala.",
