dc.description.abstractPlaying cattle in the modern livestock farming is a very important field of science and very complex primary production phase, where it has a direct impact on the creation of larger quantities of animal products (meat, milk). The aim of the research was to determine the basic reproductive traits in heifers and Simmental cows, which are grown on the farm of Agricultural good "Rogatica" Borike (RS). In the first part of this study analyzed the indicators for the 35 heifers, the first calving. Heifers are achieved average age at first conception of 18.92 months, or 567.6 days, which represents a satisfactory age at first fertilization. The average age of heifers at first calving was 28.41 months or 852 days. The average duration of first pregnancy rates amounted to 284.72 days. The ratio of male to female calves at first calving was 55.56% male: 44.44% female calves. On the basis of the set goal of research and study results, we can conclude that the analyzed reproductive parameters of cows at the farm "Rogatica" satisfactory.en
dc.description.abstractReprodukcija goveda u savremenom stočarstvu predstavlja veoma značajnu oblast nauke i veoma složenu osnovnu fazu proizvodnje, gdje se direktno utiče na stvaranje veće količine animalnih proizvoda (mesa, mlijeka). Cilj istraživanja je bio utvrđivanje osnovnih reproduktivnih osobina kod junica i krava simentalske rase, koje se uzgajaju na farmi Poljoprivrednog dobra „Rogatica“ Borike (RS). U prvom dijelu ovog istraživanja obrađeni su pokazatelji za 35 junica, u prvom telenju. Junice su ostvarile prosječan uzrast pri prvoj oplodnji od 18,92 mjeseci ili 567,6 dana, što predstavlja zadovoljavajući uzrast kod prve oplodnje. Prosječan uzrast junica pri prvom telenju iznosio je 28,41 mjeseci ili 852 dana. Prosječno trajanje prve steonosti je iznosilo 284,72 dana. Odnos muške prema ženskoj teladi kod prvog telenja bio je 55,56% muške : 44,44% ženske teladi. Na osnovu postavljenog cilja istraživanja i dobijenih rezultata ispitivanja, može se zaključiti da su analizirani reproduktivni parametri krava na Poljoprivrednom dobru “Rogatica“ bili zadovoljavajući.sr
