Adenocarcinoma of the jejunum in two cows.
Two cows from separate farms were examined for gastrointestinal disturbances. The first animal had an acute gastrointestinal disturbance with colic and the second animal had chronic weight loss and anemia. Both cows had jejunal adenocarcinoma with metastasis. They were euthanized and necropsied. Adenocarcinomas of each cow were similar histologically. Adenocarcinoma of the intestine is a rare disorder of cattle, but may present as either an acute or chronic gastrointestinal disturbance.
