Abomasal and Third Compartment Ulcers in Ruminants and South American Camelids

Abstract

Abomasal ulcers are frequent incidental findings in necropsies of domestic ruminants and South American Camelids (SAC) or in slaughter animals and are a frequent cause of death in the most affected group of cattle, veal calves. Their true prevalence and significance is unknown owing to limitations in diagnosing the condition in live animals. This article discusses types of ulcers, possible causes of ulceration, and the clinical consequences, symptoms, and differential diagnoses, as well as further diagnostics in cattle, small ruminants and SAC. The limited treatment options and possibilities for prevention are reviewed.
