The use of Holstein bulls for improving dairy cattle

, : The use of Holstein bulls for improving dairy cattle. Molochnoe i Myasnoe Skotovodstvo ( 1): 33-35

The use of crossing with Holsteins and Red and White Holsteins (RWH) to improve the milk yield of dairy cows in the former USSR is discussed. The crossing of Holsteins with Russian Black Pieds has resulted in marked increases in milk yield. In some herds, crossing has resulted in lower milk fat and protein percentages. The reproductive performance of crossbreds has not been inferior to that of indigenous Russian breeds.

Crossbreds exceeded Kholmogors by 4-48 kg for 18-month weight, 472-1579 kg for milk yield in the 1st and 2nd lactations, and 0.01-0.7 for milk fat percentage.
