[QUOTE="Ebenezer, post: 1850730, member: 24565"] It depends on the skill of the breeder. If you use old AI bulls, you cannot rely on the EPDs. The breed disses the old animals and gives them poor EPDs. In those cases, you deal with experience, advice from older folks or reported individual data. The AAA has a table of yearly EPDs and AHIA averages. The weaning weights have not changed much and the EPDs look like the sky is the limit. Until the industry addresses the inadequacies of the current EPD system/calculations there will be skepticism and rightly so. To favor young animals is merely marketing at it's best (for the seller) or worse (for the buyer). Like it or not, the rapid turnover of generations is a major problem in the industry. #1 it seems to indicate that there is less useful life in an adult to need to roll it out of the way ASAP. #2 the hope is on predicted usefulness and not on data drive usefulness. Did Ol' Bessie or Big Bud have good feet and fertility at age 4 or not? That type of information, good or bad, can help a thinking breeder avoid wrecks. #3 Buyers will buy herd prefixes for more dollars without as much consideration for the animal quality. One local big name herd generally has a bull or two each sale with actual or adjusted YW of 900 to 1000 pounds even after development. Is that progress or just mass sales efforts for the almighty dollar? [/QUOTE]
