[QUOTE="cbcr, post: 1161183, member: 16303"] If your cows now are Simangus you have 2 breeds (Angus and Simmental), if they are the result of breeding an Angus to a Simmental then you have 100% hybrid vigor. If they are bred to a Hereford bull, the resulting offspring again will have 100% hybrid vigor. As in your question, if you were to retain heifers and breed them to a Gelbvieh again you would have 100% hybrid vigor. Now you have animals that are the result of 4 breeds, if you were to keep replacements from these and then cross them with Angus, keep replacements from this mating and breed them to Simmental, keep replacements then breed to Hereford, keep replacements and breed to Gelbvieh this would be a 4 breed rotational cross. You would have a 93% retention of hybrid vigor. If you were to have animals that were a composite of the four breeds each contributing 25% and breed those animals you would have animals that would have 75% hybrid vigor. Please go to this link on our website, we have a chart there that shows the amount f hybrid vigor resulting from various breeding scenarios.
