[QUOTE="dph, post: 155387, member: 2112"] I was under the understanding that Express had indentified the first 10 star bull. It was a calf bought from Green Gardens Angus. I believe it is called PrimeStar, being a grandson of Gardens Prime Time. Bovigen has shown, through an independent verification process, that the identified genes do have a significant impact on the traits they are labeled for. While there is still variables in management, etc, these tests indicate the genetic potential for the animal and indicate how likely it is that a copy of the desirable gene will be passed to its offspring. The significance of a current "10 star" bull is that all his offspring will carry at least one copy of each desired gene. If he was mated to a corresponding "10 star" cow, all offspring would be "10 star" animals. You can see, in light of AI and embryo flushing, how breeders are interested in this. The key is, the fact that he is a 10 star bull, doesn't denote anything about maternal ability of his daughters, growth performance of his calves, or even his own confirmation. A 10 star animal really doesn't have any more likelyhood of being a bull rather than a steer, save the identical copies of 5 desirable genes. I do worry that in the short term the GeneStar program might promote the purchase of some bulls that would have made better steers. But once someone does get that million dollar bull, they are really going to turn around and feature his offspring. (In fact, I guess banking that there will ever be a "one" is a bit of a gamble. This looks like it has all the makings of the TV and Computer business, where whatever is on the market today is guaranteed to be old news in just a few months. How many genes for how many desirable traits are there to identify?) The last time I spoke with a rep from Bovigen they were thinking there were 5 to 6 significant genes impacting each marbling and tenderness, the potential for 20-24 "stars." There is no guarantee that a bull that has 10 stars today, will continue to carry the genes as they are identified and verified. It is possible that someone's current 6 star animal could prove out to carry the most copies in the future. While more is better, banking right now that one bull is going to be the "one" in the GeneStar program is nothing more than a gamble, in my opinion. By the time you start to get calves out of him, everything could have completely changed. And I do think Doc is dead on. When they begin to do this for other traits, even base EPDs off genes, it will really change things.
