Do you know the genetics of your cows? In other words are they mixed up commercial cows or are they registered? Most people will say cross this with this and breed this to that.You can do your breeding that way,and it may work sometimes. Don't ever let anyone tell you that genetics don't matter,because they do.Even most[not all],club calf breeders either have registered cows,or have no doubt how they are bred. I have seen Hannibal for example throw some kick-ass calves out of some bloodlines and complete dogs out of other bloodlines that were of equal quality,phenotypically. On straight bred good structured,good muscled,small to low moderate cows he works good as any.
