Meat Production of Holstein Friesians in Comparison to Dutch Friesians and Dutch Red and Whiteimportance, because they have to be spread over 5 years. The differences between these breeds in the value of the newborn bull calves are rather large and are of importance, because they will return on average each two years on a cow basis,

Ability of Holstein-Friesian, Dutch Black and White And Belgian White-Red Bull Calves for Veal and Btensive and semi-intensive beef production systems) were the most unfavourable for the Holstein breed..Except for the colour of the veal calves, the meat quality characteristics were not significantly different between the breeds. In all systems, the best results were obtained with the Belgian White

Influence of Economic Weights and Population Structure on Selection Response of Milk and Beef Traits introduction of progeny test of bulls and performance test of cows in the field, yield a higher genetic gain and a higher profit. Moreover, these breeding activities seem to be an effective tool to balance the genetic gain of milk and beef traits.
