[QUOTE="novaman, post: 733060, member: 2744"] Since the other thread got locked I started this one to further the discussion. I never suggested that people start culling their herds. I suggest the problem animals be eliminated ASAP. They could keep those cows and be certain to breed to a non-carrier bull. The offspring would have to be terminal and the cows eventually culled out of the herd to "clean up" the defect genes. I don't understand why everybody jumps to the conclusion that a whole herd or at least most of a herd has to be removed. This was the line of thinking back in the 50's when dwarfism was an issue. They eliminated many animals with genetics that were very good at the time. You can work around genetic defects without eliminated whole lines of animals. [/QUOTE]
