title: Suspected ergotism in two heifers.
abstract: 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.
