Effect of Crossing some Dairy Cattle Breeds with Angus Breed

The aim of this study was to evaluate the productive performances of the Holstein x Angus and Angus x Jersey females reared in intensive system. In the period 0-15 months, the highest average daily gain was recorded in the heifers Holstein x Angus, followed by Angus x Jersey. These results showed the genetic power of Angus to transmit this character, both on the paternal line (the most obvious effect) and on the maternal line. In the Holstein x Angus females, the father's influence led to a decrease in the amount of milk. In the Angus x Jersey cows, the milk yield was 30.3% lower, as a result of the paternal influence of the Jersey breed. The percentage of fat was higher in Angus x Jersey females, knowing that Jersey's milk is much fatter (5.5 - 6.5%). The crossbreeding between milk breeds and Angus is recommended for profitability of small farms, because F1 females provide a fairly high milk production, and F1 males can be raised for meat.
