dc.description.abstractThe basis for selection work is knowledge of the quality of bull sires used for conception, as well as how the major traits are passed on to the progeny. BLUP method (Best Linear Unbiased Prediction) is the basis of the most favourable solution for evaluation of additive gene value in cattle production, and it is implemented in various variants depending on the structure of data used. This research included 2.121 Simmental first cavers under control, with lactations completed within one year. All first calvers were located on holdings of individual agricultural producers on the territory of the Republic of Serbia. Evaluation of the bull breeding value for lactation duration, milk production, milk fat yield, yield of 4% FCM and percentage of milk fat, was carried out by using the mixed model (BLUP), the calculation included random effect of bull sire and fixed effect of the region, year and season of calving. In this study, bull sires which had in two or three regions over 20 daughters - first calvers of Simmental breed. Number of first calving heifers ranged from 22 to 215 animals per bull sire. By using BLUP method in evaluation of breeding value of bulls in terms of yield of milk, milk fat, content of milk fat and 4% FCMI and by ranking, results were obtained showing superiority and inferiority of breeding males.en
dc.description.abstractOsnovu za svaki selekcijski rad predstavlja poznavanje kvaliteta bikova očeva koji se koriste za oplodnju, kao i način prenošenja važnijih svojstava na potomstvo. U osnovi najpovoljnijeg rešavanja problema ocene aditivne genotipske vrednosti osobina u govedarstvu leži BLUP metod (Best Linear Unbiased Prediction), koji se primenjuje u raznim varijantama zavisno od strukture podataka. Ovim istraživanjem je obuhvaćena 2.121 kontrolisana prvotelka simentalske rase, sa laktacijama zaključenim u toku jedne godine. Sve prvotelke su se nalazile na imanjima individualnih poljoprivrednih proizvođača na području Republike Srbije. Ocena priplodne vrednosti bikova za osobine trajanje laktacije, proizvodnju mleka, mlečne masti, 4% MKM i procenat mlečne masti, izračunata je pomoću mešovitog modela (BLUP), u čiju jednačinu je uključen slučajni uticaj bika-oca i fiksni uticaj regiona, godine i sezone telenja. Ispitani su bikovi-očevi koji u dva ili tri regiona imaju 20 i više kćeri prvotelki simentalske rase. Broj prvotelki je bio od 22 do 215 po biku-ocu. Korišćenjem BLUP metoda za ocenu priplodne vrednosti bikova na prinos mleka, mlečne masti, sadržaja mlečne masti i 4% MKM i formiranjem ranga dobijeni su rezultati koji pokazuju znatnu superiornost ili inferiornost priplodnjaka.sr
