I believe there is good and bad in every breed. Have no idea what the epd is I don't believe that some of their dna epds have anything do with the way the cattle actually are. Haven't ever been around Hereford so don't know what they are like. Imho I think the biggest problem is that seedstock producers and probably even commercial producers don't cull hard enough for such problems. We got a Charolais bull from a local producer cause one of ours went bad and that thing was wild and the bull producer wouldn't do nothing about it. How does focusing on 2-4 certain traits when seedstock producing makes a problem?
