ABS Genetic Defect Information
TH is a disorder of multiple congenital defects seen in calves. Translated, the name refers to absence of all or part of the tibia (tibia = the bone between the knee and ankle in humans or the stifle and hock in cattle and hemimelia = absence of all or part of a limb). But TH encompasses more defects that the name implies. TH is lethal, as the calf may be born dead, but if not dead the condition is incompatible with life. These valves have large abdominal hernias (weakening of the abdominal muscles that allows intestinal contents to bulge out), twisted legs sometimes with absent or deformed bones.
Backhoe, I don't think what you experienced was TH. TH affected calves are almost always born dead, and those that are not will not be helped by splinting. The hernia mentioned is also unmistakable, their bellies look like they swallowed a basket ball. The cow is usually a casualty as well in TH positive matings. The defect is thanks to a specific bull in the shorthorn breed, an as far as I'm aware, has yet to be found in the Wagyu breed.
