The use of Holstein bulls for improving dairy cattle
Spivak, M., 1990: 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.
