[QUOTE="Son of Butch, post: 1095003, member: 14585"] F1 bulls should look better than their purebred ancestors, they are using up the heterosis or hybrid vigor for themselves. I guess if you get a couple more seasons of breeding out of them vs purebred bull, I guess maybe it could be justified. I've seen good looking calf crops from them, it's just that within the group the calves favor one breed of the composite and more sorting to make a uniform group. It would be interesting to see head to head performance data on calves sired by composites vs same breed purebreds that make up the F1 cross in question. I don't know of any legit performance research that has ever been done on F1 sires vs purebred sires. Maybe I should check to see if its been done with hogs. Genetic performance research can be done much faster with hogs than cattle. I don't suppose there are any hog farmers out there reading this, but if so comments would be welcomed. [/QUOTE]
