My point was the eighty twenty is the extreme because the show world is extreme in the type they want.
If a bull is being promoted thatheavy, and used that heavy and is not improving the breed then those that use him are going to find out the hard way. I do see the problem with the disconnect between the rail and the pasture they come from. The guy that feeds them the last ninety days may not be the guy that backgrounded them, and very likely is not the guy that bred and raised them. Therefore, if the feedlot guy does know what breeding is behind the calves that didn't or I'd cut well, it is far from the norm. Any black. Cattle that go through the sale barn at local sale barns are called angus cross. We raise limis. Most of our herd would be at least three fourth limi, but last year when they went through the auctioneer said, look at these thick made angus steers! We corrected him, but how many people really follow there calves to the rail. As a feeder calf producer, weaning weight is what you are after, If they don't cut, that is the next guys problem.
That is the problem, like I said genetic diversity is tempered with improving the breed. I don't want to see every pos bull calf sire twenty calves. But with the ability for several bulls to be marketed so heavy, care needs to be taken that the ones being chosen are right. Lack of uniformity in cutability, gain, grading etc is what the market place is calling for. A commercial cow calf guy being able to sync all his cows, get seventy five percent bred the same day to the same bull is going to have a much more uniform product to sell, then the. Same guy taking three hundred calves sired by ten different bulls spread out over five weeks to the market. If he picked the wrong bull, then that is a problem, but that is not because of gentic diversity, it is picking a bull that does not produce what was promoted.
