Abstract

THE toxicity for livestock of mouldy sweet potatoes has been recognized for several decades in the United States1 and, especially, Japan2. The few reports available describing toxic manifestations mention pulmonary oedema, emphysema and adenomatosis as characteristic disease signs in cattle involved in natural outbreaks3–5. These disease signs have also been attributed to other moulded feed products, silage and lush pasture grass6. Somewhat similar effects have been observed when large doses of tryptophan were administered to cattle7.
