Features of conformation type of black-andwhite cows of different origin estimated by linear classification method

The research was carried out in the aspect of studying features conformation type cows Ukrainian Black-and-White dairy and Holstein breeds estimated by linear classification method. Basis for herd company "Ukrlandfarming" private enterprise "Burynske", Pidlisniv branch Sumy region. aim to conduct a comparative analysis experimental according assessment determine impact final score on milk productivity first-born cows. In general, both were characterized good estimation, especially 100-score scale. However, animals breed comparison with better terms body parts, which characterize 1.3 score, - 0.8 udder 1.2 (P <0.001). On trait chest width, inferior their reliable difference but exceeded angularity strength fore parts attachment central ligament 1.1 estimation level directly proportionally determined 305 days first lactation. Cows Black-andWhite "very good" peers "good plus" milking 785 589 kg (P˂0.01) respectively, "good" 1705 1502 (P˂0.001). use selection process cattle, determining breeding value, method will be very effective means objective definition type. presence correlative relationship between contribute effectiveness indirect sampling these traits.
