Actually maximum heterosis and maximum consistency occur at the F1 cross. If you cross a horned Hereford with a black Angus, the resulting calves will all be heterozygous black, polled and white faced. Crossing an F1 black baldy to an F1 black baldy will result in 64 different genotypes and 8 different phenotypes.Thanks for the detailed post showing your thought process. I agree with your thoughts. I was hoping to get a little more reasoning from Travlr on his strongly held beliefs. The use of a crossbred bull is probably not the best plan for most herds. But there are some differences in crossbred bulls. I would see little if any benefit of a Chianina-highland cross bull for instance. But to decide that all crossbred bulls are bad simply because they are crossbred - that might show as much bias as reasoning. I always enjoy reading a different opinion when it is presented with a logical set of reasons.
Part of the topic is consistency and part is heterosis. Those two things probably do not go together. A person could have a very consistent set of calves, but they could be consistently bad. Max heterosis probably does not give max consistency. It is not black and white.
I think the thought process for many is from the view of a commercial herd with multiple breed cows. And a strongly held belief that breed associations should only exist for the purpose of breed purity instead of data collection, pedigree documentation and giving choices to producers. But there are also many seedstock producers that are producing and using in their herds these "crossbred" bulls with considerable success and acceptance. And the demand is there.
Some here even believe that any black simmental, limousin, or gelbvieh are really angus, so maybe those simangus bulls are purebred anyway.
A big reason why the tiger stripe is more popular than a braford is that it has all the Brahman genes and all the Hereford genes. Where as the braford has had its genetics reduced.
