[QUOTE="smnherf, post: 229694, member: 3235"] I have done a lot of research on heterosis and the conclusion I come to is that you will make more money by haveing the heterosis in your calf crop and in your cow herd rather than in your herd bull. Some of the big composite marketers near me who use the theory of 'simple solutions to complex crossbreeding problems' is very misleading. Because if you use more than 2 generations of a composite bull in your cowherd, you will have less heterosis in your calves than if you simply used a simple two breed rotation. Since most people have cows older than 2 years, you will still have to use a different composite bull on your young cows than you use on your old cows. Ultimately you end up with a cowherd that has 4 or 5 breeds of varying percentages in it and keeping trackof it can get pretty complex. Bottom line, there is no easy way to maximize heterosis unless you are willing to sort your cows according to breed percentages and then mate your cows to bulls of unlike geneotypes. Plus, I haven't even mentioned the effect it has on your cowherd over a period of time. [/QUOTE]
