Does anyone have any data on steers winning big that were ds carriers? I think the reason there are no clean ds Shorthorn sires out there is because if they aren't carriers.......they don't have the look to be bulls.......kinda like the th free cattle won't win the steer shows. Looks almost like to me the ds defect is simply another tool in the steer jockeys arsenal. They will shoot for the ultimate th carrier,pha carrier, and now also ds carrier. I am afraid the ds defect has put a fork in the Shorthorn breed in alot of ways. maybe 100 years not so much if clean lines are developed it the breed. But there are just to many choices out their in the beef industry......why mess with a breed will all these defects? Its just another head ache. When you can go to the Angus, Red Angus, and other breeds that ban defects.
