A:   I assume that your cows are either straightbred Angus or high percentage Angus. If this is the case then I think it would be a good idea to consider a different breed of bull in order to capture heterosis in the resulting feeder calves. There are several options depending on your particular goals and preferences but in general a Continental breed should add the most hybrid vigor when mated to your British cows. If it is important to you to maintain a black hide in the feeder calves for marketing purposes then Gelbvieh, Limousin, Simmental, or a Maine bull would all be possibilities. If color does not matter, then Charolais would be a possible choice. All of these breeds would have the potential to increase weaning weights and add more muscle to their calves. Another possibility would be to use a composite bull such as a Hybrid Simmental (Simmental x Angus), LimFlex (Limousin x Angus) or a Balancer (Gelbvieh x Angus). If you would prefer to have calves that are predominately of Angus decent, with a little Continental influence, this would be the way to go.

As a side note, the benefits of crossbreeding will be visible in your feeder calves but also in the maternal performance of the crossbred females if you retain replacements.
