If a Shorthorn Red Angus cross can't be registered as a Durham Red because it test positive for TH, could it be registered as an Appendix(Shorthorn Plus)? I saw a heifer calf in a sale flyer that was listed as a Durham Red but in the footnotes said it was TH carrier. They also said registration was pending. I've since lost the flyer and can't remember the bloodlines or where the sale was. My wife claims I send more time with sale catalogs and flyer this time of year than I do with her and the kids. Hmmm, maybe that's where that flyer went..
