Abstract

The article presents the data on productive and reproductive qualities of cows of Holstein breed depending on genetic factors. The cows of the line by R. Sovering were characterized by higher productive qualities during their first and third lactation. Cows of all three lines are characterized by the optimal duration of interaction period and longer service period, which lead to an increase in the calving interval. In the process of studying the effect of different methods of selection on milk productivity of Holstein breed cattle, the authors found that during intra-line selection higher productivity is characteristic of the selection by R. Sovering and V.B. Ideal. The period of production use of the analyzed livestock amounts to 2.8 lactations. Cows from the M. Chieftain line are characterized by 3.0 lactation. At the same time the eliminated cows of the line R. Sovering were characterized by higher productivity, the yield for lactation made 8462.8 kg.
