Research concluded that household utilization indicators of Ukrainian black spotted dairy breed cows were considerably influenced by their parents. Better indicators of household utilization were revealed in daughters of Holsteins’ bulls inseminators Baritone 18, V.P.V.Starbuck 389756 and M.Brun 5488517. High part of bulls’ influence were upon daughters milk yield per one day of lactation (41,08 %) and one day of household utilization (40,70 %), average milk fat content per all lactations (34,61 %), life expectancy (24,09 %), household utilization expectancy (22,82 %) and amount of lactations (22,43 %). |
