AB  - The objective of this research was to determine the association between age at first calving (AFC) and milk production in the first lactation of longevity traits for Holstein cows. The research was conducted on 2307 cows raised on 4 farms in AP Vojvodina. The cows were culled in the period from 2017 to 2018. The cows belonged to the group of Holstein Friesian breed of cattle. Cow longevity was observed using three parameters: number of lactations (NL), lifetime milk yield (LMY) and length of productive life (LPL). The research involved the influence of the farm on which the animals realized their production, the season of first calving. A mean value obtained for the length of productive life in the analysed population was 1207 days (3.30 years on average). During this period the animals on average realized 2.45 lactations and produced on average 18798 kg milk. All studied traits showed a high level of variability. From these data, the study sought to determine the influence of factors on the traits of longevity, our research present that studied factors showed high statistical significance on these traits except in the case of the season of first calving where a statistical significance effect wasn't observed. The season of first calving did not affect the animal traits for longevity and, generally, didn't affect the calving interval. Regarding the obtained correlation data between age at first calving and length of productive life, it can be concluded that belated AFC leads to reduced reproductive performance.
AB  - Sprovedeno istraživanje imalo je za cilj da utvrdi povezanost između uzrasta pri prvom teljenju i proizvodnje mleka u prvoj laktaciji sa osobinama dugovečnosti za krave holštajn-frizijske rase. Istraživanjem je obuhvaćeno 2307 krava, sa 4 različite farme sa teritorije AP Vojvodine. Krave su izlučene u periodu od 2017 do 2018 godine. Dugovečnost krava je posmatrana kroz tri pokazatelja: broj ostvarenih laktacija (NL), životna količina proizvedenog mleka (LMY) i dužina produktivnog života (LPL). Prosečno trajanje produktivnog života za sva grla uključena u analizu iznosilo je 1207 dana (3.30 godine u proseku). Grla obuhvaćena analizom u toku svog produktivnog života su prosečno proizvela 18798 kg mleka. Broj laktacija koje je svako grlo prosečno ostvarilo u toku trajanja svog produktivnog života iznosio je 2.45, pri čemu su svi ispitani parametri pokazali visok nivo varijabilnosti. U istraživanju su ispitani fiksni uticaji farme na kojoj je grlo proizvodilo, uzrasta pri prvom teljenju, sistema proizvodnje i sezone pri prvom teljenju na osobine dugovečnosti i međutelidbeni interval, korišćenjem linearnog modela. Na osnovu rezultata dobijenih istraživanjem, fiksni faktori su pokazali visoku statističku značajnost za ispitivane osobine, osim u slučaju sezone pri prvom teljenju, gde nije ispoljena statistička značajnost za osobine obuhvaćene istraživanjem. Na osnovu rezultata, utvrđena je povezanost između uzrasta pri prvom teljenju i dužine produktivnog života, pri čemu se može zaključiti da su kraći produktivni život imale životinje koje su se kasnije telile.

AB  - Simple Summary: Cattle have been selected for their adaptation to a specific environment and productive system, in which they show, in theory, their best economical results. With appropriate nutrition, the calf's performance enhances during early life and improve the production limit providing distinctive opportunities to optimize feeding strategies and increase the profitability of beef production. There is considerable variation in fattening protocols as well as in farm conditions. Meat quality parameters and carcass traits are the main objectives of most research carried out in the beef production area. Optimizing meat quality parameters and carcass traits are important for farmer profits and consumer satisfaction. According to that, at the phenotypic level, growth performance and traits could be observed. Rearing practices are known to have an impact on cattle carcasses and meat characteristics. The rearing practices applied after calving have an influence on the animal's performance at the growth period and can involve different animal properties at the beginning of the fattening period. Abstract: This study assessed the effects of farm management during rearing practices in the first months of a calf's life on growth performance and meat quality traits during the fattening period. A total of 48 Simmental calves were divided into two groups at a commercial cattle feedlot. In the first group were calves from the same farm and herd (n = 12 male and n = 12 female). The second group included calves from several different herds and farms (n = 12 male and n= 12 female). Calves were transferred to a feedlot and fed with a commercial feedlot ration at three to four months of age. The aim was to determine if identical fattening conditions at feedlot can reduce initial calf rearing differences between cattle during the fattening period. Bulls grew faster than heifers reaching higher total gain and showed significantly higher slaughter weight than heifers. Meat samples of heifers from the same herd had the highest intramuscular fat content and reddest color with significant differences among cattle groups. The most abundant fatty acid was oleic acid (C18:1), followed by palmitic (C16:0), stearic (C18:0), linoleic (C18:2), and myristic acid (C14:0). Meat samples of heifers from different herds were darkest with highest content of iron (Fe) with significant differences among cattle groups.
