Pfizer Animal Genetics now running Contractural Arachnodactyly (Fawn Calf) test

NEW YORK ─ Oct. 6, 2010 — Pfizer Animal Genetics is now accepting samples for Contractural Arachnodactyly (CA) testing. CA is a genetic condition formerly referred to as Fawn Calf Syndrome. Through the 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. Pfizer Animal Genetics is approved by the American Angus Association as a CA testing laboratory.    

CA is a nonlethal 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 (particularly hip, stifle and hock) have a reduced range of motion. Calves appear normal by 4 to 6 months of age, but most perform poorly and are relatively tall and slender, with compromised feet and leg conformation.
