I just thought of another example of the shorthorn breed not chasing TH. (Not that we need anymore examples, but I think it's an interesting testament to the big breeders approach to not propagating the defect). In the early 2000's there were 2 Shorthorn Bulls that sold for $100,000 - Reno & Centurion. Obviously, commanding prices like that is kinda a big deal and a lot of people saw these Bulls as "the next big things". I, along with others I knew, were shocked when it was published in Shorthorn Country that they were THC. Although they were bred different and looked different they had one thing in common - Improver 57 as a grand sire. Despite the early hype and promotion, these Bulls are relatively unknown today and not found very often in pedigrees. I believe this is due in large part to them carrying a lethal defect, TH..
Now for the Paul Harvey "The Rest of the Story". There was another bull born in 03 that didn't receive the pomp and circumstance that followed Reno and Centurion. Not sure he came close to 6 figures either. However, similar to his THC cousins, this bull had Improver 57 as a great grand sire. Fortunately, unlike his cousins he nor his parents or grand parents inherited the lethal defect. He was an outstanding, beautiful R/W/M bull purchased by a new breeder who had big plans for the future. In only a matter of 3 years this bull, without the aid of TH, would go on to change the Shorthorn showring forever, and make people all but forget about Deerpark Improver and TH. The Bulls name was CF Solution and the upstart breeder who selected him was Sullivan. CF Solution sired the most recent National Champion and Reserve National Champion Shorthorn Bulls...something he has done many times previously.
