justintime said:That is exactly how I have thought it would be spread into the commercial industry.I know of breeders who think nothing of selling their TH carriers to commercial breeders. One guy told me, " like who is it going to hurt... he is crossbreeding?" My point has been from the start of this defect issue's appearance is that we have no control over what happens in the future after you sell the commercial producer a bull ( or set of carrier females). The guy may like the calves and retain some daughters that are carriers. 10 years from now he may buy another carrier bull or AI some cows to a clubby carrier bull.
I had a TH calf two years ago from a cow that had Deerpark Improver back 9 generations. No other carrier bloodlines were used after that one shot of Improver... which only proves that this defect can be managed.... but you certainly have to study your lessons and know exactly what is in your cows for a long ways back.This was a female that I had purchased and the breeder had said she was TH free by pedigree. He had not researched the pedigree far enough on either the sire or dam. The sire of the TH calf had Improver back 6 generations, and I was aware of that, and thought that the sire was TH free because of the sale catalog statement that this lot was TH free by pedigree. I never assume anything anymore.

Telos said:As far as PHA. I believe we went back to a French bull named Univers as a possible carrier, but is impossible at this time to prove. The Sibelle cow may have been the dirty cow in Stinger's pedigree.
