[QUOTE="elkwc, post: 1692214, member: 22295"] Katpau as a commercial breeder I have found both to be of little if any benefit in bull selection. You mention BW. I have found both to be very misleading in BW also. Just this year I have talked to 3 breeders who used the same bull on heifers. He had good BW numbers both on genomics and EPD's. All 3 breeders had a wreck on the heifers they used him on although their heifers bred to other sires calved fine.His BW EPD dropped to a 6 I think. I have went back to only using a bull on heifers that has at least one calf crop on the ground and preferably 2. I select a bull by actual numbers, measurements and type. The low accuracy EPD's and genomics don't work for us. [/QUOTE]
