complex estimation of Holstein sires and Black Pied breeds. According to the rating productively constitutive featuresfresh cows found that improvers of milk yield recognized bulls - Jacob 132065115 (+1726 kg), Genghis 982 (+1030 kg), Mistral79325755 (+ 895 kg). Positive effect on the fat content of descendants had Holstein bulls: Siemens 1869 (4.06 %, + 0.09)and Reverse 2708 (4.03 %, + 0.06). High yield of milk fat and milk protein stand daughters of sires: Quintus 1317 (4.27 %;3.26 %, R ≤ 0.001) and Mod 3591 (4.07 % R ≤ 0.001; 3.20 % R ≤ 0.05). Milk body type is transmitted to descendants Holsteinbulls: Jacob 132065115, Genghis 982, Mistral 79325755. Overall the complex of symptoms varies from 80.4 to 81.0 points andcorresponds to the international category «Good Plus».
