Genetic Defects
In almost any genetic population genetic defects show up from
time to time. Recently in Shorthorns a recessive genetic defect
known as Tibial Hemimelia (TH), has shown up in Shorthorns. The
University of Illinois is able to conduct tests to identify carriers
of TH. At the present there is not a facility to conduct these
tests in Canada. If you use the following link to the American
Shorthorn Association site you can find out more information
about TH. Recently a new genetic defect Pulmonary hypoplasia
with anasarca (PHA) has been reported in 4 shorthorn calves.
More information on PHA can also be found on the ASA website.
Canadian Breeders who wish to test for the TH defect are able
to submit samples to the lab in Illinois. Please contact the
Canadian Shorthorn Association for the required permit and submission
forms at 306-757-2212, email office@canadianshorthorn.com,
