ERGOTISM, GANGRENOUS, HYPERTHERMIA, ERGOT TOXICITY IN RUMINANTS
 
Description    Ergotism is often due to ingestion of grains infected with CLAVICEPS PURPUREA. Signs can vary from mild to severe. Non-painful progressive gangrene seen with ergotism is usually worst in the extremities, particularly the hind limbs, tail and ears. Some authors suspect that there can be abortion in the absence of skin changes. There were reports of hyperthermia, respiratory distress and loss of production in Australian cattle fed feed contaminated with CLAVICEPS PURPUREA and in African cattle consuming feed containing CLAVICEPS CYPERI.
