title: Abomasal ulcers in captive white-tailed deer (Odocoileus virginianus).
abstract: Abomasal ulceration was noted in 32 of 200 white-tailed deer. Ulceration was most common in the abomasal pylorus and at the abomasal-duodenal junction. Abomasal ulceration was characterized by focal to multifocal, sharply demarcated areas of coagulation necrosis and haemorrhage extending through the mucosa, with fibrin thrombi in mucosal blood vessels of small diameter. Ulcerated areas were often covered by a mixture of mucus, debris and neutrophils. Visible bacteria were not associated with ulcerative lesions. All deer with abomasal ulceration had intercurrent disease, including bacterial pneumonia, enterocolitis, intussusception, chronic diarrhoea, capture myopathy, or experimentally induced tuberculosis. The anatomical distribution of abomasal ulcers in this population of captive white-tailed deer resembled that seen in veal calves.
