摘要：

In a calving ease comparison involving 106 calves born to first calf heifers, calves sired by Red Angus bulls were heavier at birth and required mom calving assistance than Corriente-sired calves. However, the easier calving Corriente-sired calves experienced equivalent death loss and were significantly lighter at 3, 5 and 7 mo of age.
