TH just isn't in post legged "steer bulls" it is everywhere. Some of the most respected commercial breeders in the nation have knowingly or unknowingly used carrier genetics. Go look at a pasture of Improver 57 daughters and tell me that we need to get rid of all carrier cows or that they have no place in the industry. There are numerous THC cows that can have a tremendous commercial impact through their THF offspring. Test all of her calves and if they are THC cut the bull calves and keep the heifers that will improve your herd. If they are THF the sky is the limit. There is a fine line that can be walked with this whole genetic defect situation. IMO those who are able to get the positive traits from carrier lines in a none carrier animal will be ahead in the long run. One of the happiest days of my life was finding out that our Dream Girl donor was THF. However if she was THC it wouldn't have made her any less of a cow in our eyes because 50% of her calves would still be THF. We have several pregnancies coming out of her and Eagle 148 this spring. We feel this is an outstanding mating, and even if she would have been THC there would be at least one THF son that could do the breed a world of good. My biggest frustration with PHA and TH is the perception that it only occurs in show cattle but that couldn't be farther from the truth.
DL, I'm not going to watch your video(I can't even watch doctor shows on tv) but thank you for posting it. I think it is important to educate people on what can happen when carriers are mated to carriers. We have never had a TH or PHA calf but just the thought of what could happen is enough to prevent me from mating carriers. IMO most people who bred carriers to carrier don't think defective calves can be that bad but hopefully now people will realize what a gruesome result is possible.
ITK,
I respectfully disagree. If you care to look closer, you'd see, BY AND LARGE, within the American Shorthorn Association's "North American Breeding Population" ( our fellow Canadians are in this mess, too) the "Genetic Defect" situation IS associated with Clubby Bulls. Let's look at why I believe this. Hear me out.
Back in the heyday of Continental Domination, you couldn't sell ANY Performance-tested Yearling Bull of ANY "British" Breed ( Except South Devons). Not even Angus. To save our butts, We, as a Breed, turned inward, and "did our own thing".
About this time, the Jackpot Show was evolving from a teaching tool for Agricultural Youth, and had begun to transform into a Varsity Sport, especially in the "Western" and "Corn Belt" States. Some Breeds' only salvation was this new, "Niche Market". Hence, you could sell Shorthorn Steers as "Project Calves" for a slight premium over the scale ( provided they had the right physical make-up), when, I'll say it again, A Producer, no matter how good their Shorthorns were, would get their "hat" handed to Them (like an unlubricated Scour Bolus) each (and every) time He or She marketed said calf crop through the local feeder calf auction.
Also, about tis time, the "80's" and its Financial Fiasco (not just in Agriculture) really changed the Midwest, unfortuneately, forever. Many pastures were plowed under when neighbors bought neighbors' farms after the bank stepped in. Gone,along with these Families ,were the Herds of environmentally-adapted Cows who ate frozen Corn Stalks (NOT STARCH) all winter long ( without supplementation and/or shelter--not even a windbreak), then spent the summer grazing weeds and unimproved, native grasses,on ground "not good enough to Farm", while raising calves that set the "standards" for Marbling, flavor, and Tenderness. I believe, for the most part, that calves produced in tis scenario were what most Americans would associate with "Midwestern Beef". My Uncle was a Trucker, and as a boy, I'd ride with Him up to St. Louis and Chicago, or other "quick jaunts" through the Heartland. Each year, I'd notice, as We drove through the same parts of the Midwest, Livestock and fences were disappearing--FAST.
Back to Shorthorns. If you'll look at the lineage of most "carriers" you'll see 2 common Ancestors--Deerpark Improver and Stinger."Irish on a Maine". In a nutshell, the basic (successful) recipefor producing show-steers. That supports my belief that "steer sires" ARE mostly responsible for this Crap.Well, actually, the People who continue to breed them are resonsible, No Offense.
Now that We know Who the Carriers are, I believe, We already have enough "Clean" offspring to perpetuate their beneficial DNA.
Yes, I like ol' "Red 57th"'s daughters. I like "Darth Vader" (IDS Improver 2K)Cattle even better.
I haven't had a single TH calf, yet. Others on here have. The first time I do have one, and, if deliberate omission of the facts contributes to this occurrance, I will show Y'uns just exactly WHY the Civil War took so long for Y'all's ancestors to win.
