Abstract:

A herd of rising two-year-old Angus heifers and steers presented for doing poorly. Distance exam revealed ill thrift, hair loss, dull coats and watery diarrhoea among the seven presenting steers/heifers that were worst in the herd. No monitoring or sufficient preventative measures to combat sporidesmin toxicity were in place on the farm. Laboratory results showed mean serum gamma-glutamyl transferase levels to be 879IU/L. Following euthanasia on one heifer a postmortem revealed extensive bands of fibrosis throughout the liver with proliferation of the biliary ductules. The history, presenting signs, post-mortem liver changes and diagnostic tests were consistent with previous sporidesmin toxicity.
