THis is from my commercial standpoint - because we do calve out large numbers of heifers. When looking for a bull to AI to our heifers the FIRST think we look at is the calving ease EPD, the second thing is the accuracy of that EPD. The accuracy will increase with more calves on the ground. I don't think we've ever AI'd a bunch of heifers to a bull that hasn't been out there for awhile - thus proving himself. Our biggest wreck came one year with the clean up bull - a little angus yearling bull with awesome numbers. We do look at BW -actual and EPD but dont' put as much emphasis on that.
