Case records of abomasal ulcers in adult dairy cattle admitted to the University of Pennsylvania during a 12-year period were reviewed. The only records retrieved were those for cases in which the clinical signs were directly associated with gastrointestinal bleeding. Of 6385 adult cows admitted during the study period, 69 had clinical ulceration. Twenty-four were bleeding ulcers: 12 not neoplastic and 12 associated with lymphosarcoma. Non-neoplastic ulcers were commonly found in young cows (7 cows less than or equal to 4 years old) that often had concurrent postparturient. Lymphosarcoma-associated bleeding ulcers were found more commonly in older cows (10 cows more than or equal to 6 years old) during all stages of lactation, often without concurrent diseases (8 cows).
