TH carriers are heavier boned, thick, have straight back legs and lots of hair? A cow that I purchased before TH testing was available was later tested and was TH positive. She would be criticized for being light boned, perhaps too narrow, having somewhat crooked back legs, and didn't have much hair. (she was an excellent producer for 10 years) I hate to read or hear comments that they have to be TH carriers to be competitive. When was the last time a TH carrier won the National Shorthorn show? There have been 4 or 5, maybe more, national champions that were Trump X Rose 004. Not a carrier in the bunch. Bloodstone? Clean. Solution? Clean. Sonny? Clean. Anybody showing a TH positive Shorthorn bull to the National Championship lately? Not that I know of. I saw Improver on display in Denver. Has it been almost 40 years? Look at the photos of him. He was straight on his back legs, bigger hipped than most of the time, and some of us didn't like him because we thought he might be too small. He became popular because of those traits and the TH, in my opinion, was a tag along of his total genetics. Just because an animal is a TH carrier doesn't mean they are good. Check the pedigrees of the Shorthorn champions of recent years. Many of them have Improver in their pedigree, but do not carry the TH gene. Obviously, the traits those breeders wanted were passed on without TH. If I see research someday that proves moderate framed, heavy muscled, heavy boned, hairy, big hipped cattle have to carry the TH gene, then I may reluctantly admit that to win a show you need TH.
