Holstein-Friesian cattle

Holstein-Friesian cattle

(hōl`stēn-frē`zhən, –stīn–), breed of dairy cattle originated in N Holland and Friesland. Commonly called Holsteins in the United States, these large cattle with sharply defined black and white spotted markings are believed to have been bred for their dairy qualities for 2,000 years. The region from which they come was famous even in Caesar's time for its cattle. In milk production the cows average a higher yield than that of any other breed, although the milk has a relatively low butterfat content; as a dairy breed, they rank high for beef and veal production. Large numbers of Holsteins were imported in the late 19th cent. to the United States, where they are now the dominant dairy cattle. They are also widely raised in Canada, Australia, South America, and South Africa.

The aim of this work was to determine the dependency between polymorphism in the PIT-1 and fertility rates, body weight of cows and calves, the course of parturition and viability of calves in Polish Black-and-White Holstein-Friesian cattle. The analysis included 1024 cows and 3663 calves of the Polish Black-and-White Holstein-Friesian breed (phf).
