Test developed for fawn calf syndrome

Producers will now be able to test animals for Fawn Calf Syndrome (Contractural Arachnodactyly).

CA is a non-lethal genetic condition that affects Angus and Angus-influenced cattle. While CA-affected calves are born alive, and most can walk, suckle and survive, their upper limb joints have a reduced range of motion. Most calves appear normal by four to six months of age, but perform poorly and are relatively tall and slender, with compromised feet and leg conformation.

In collaboration with Dr Jon Beever at the University of Illinois and the American Angus Association (AAA) the gene mutation responsible for CA has been identified and a commercial test developed and validated. The service will now be available from Pfizer Animal Genetics.

Genetic testing is the only definitive way to identify carriers of the gene who could pass on the mutation. Producers who want to identify carrier animals can send hair or blood samples to Pfizer Animal Genetics.

Producers can find useful information and updates about the condition and download order forms and sample collection guides here.
