A syndrome similar to gangrenous ergotism was seen in 2 Friesian heifers grazing meadow hay containing perennial rye grass seed heads parasited by an ergot presumed to be Claviceps purpurea. Clinical signs were bilateral hind limb lameness and gangrene. There was angiographic evidence of vasoconstriction in the lower hind limbs with necrosis of all tissues in the distal region of both hind limbs.
在2头弗里斯兰小母牛中观察到一种类似于坏疽性麦角中毒的综合征，它们食用的草地干草中含有被推测为麦角菌的多年生黑麦草种子头，这种麦角菌被认为是紫麦角菌。临床症状为双侧后肢跛行和坏疽。血管造影显示后肢下部血管收缩，双侧后肢远端所有组织坏死。
