Abstract: In article data on the analysis of coefficients of heritability are provided in herd of cows of black and motley breed in the Orel region. Heritability of a yield of milk in 305 days, fat contents of milk, milk protein content, live weight is studied. It is defined that in herd growth of yields of milk made 1146 kg of milk for one generation, or 119.4% of relative effect of a heterosis.
