Genetic Defects There have been a few cases reported of abnormalities of the distal leg/foot and dew claws in Shorthorn calves in the States. These cases are not "classic" mule foot as the claws (toes) are not fused, typically the calf has inappropriately placed dew claws and may have some other slight curvature or deformity at the base of the leg that makes it somewhat difficult for them to mobilize. The American Shorthorn Association has produced a pdf file with more information and photos. Click here to view the file. Breeders are encouraged to submit samples of any suspected cases, as per directions on the ASA site. More information will be posted as it becomes available. In almost any genetic population genetic defects show up from time to time. Recessive genetic defects known as Tibial Hemimelia (TH) and Pulmonary hypoplasia with anasarca (PHA) show up in certain bloodlines of Shorthorns. If you use the following link to the American Shorthorn Association site you can find out more information about TH and PHA. Canadian Breeders who wish to test for the defects can submit samples to Igenity in Calgary, AB.
