(Institute for Animal Husbandry, Belgrade, 2009)
The effect of systematic factors on production traits over complete lactations was investigated in 2,805 Simmental cows born in 1982 and onwards. The cows were housed at three farms in different areas: at the Zlatiborski ...
The evaluation of breeding value of simmental bulls for milk performance in Serbia / Ocena priplodne vrednosti bikova simentalske rase za osobine mlečnosti u Srbiji
(Institute for Animal Husbandry, Belgrade, 2011)
The 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 ...
