This paper describes the clinical, laboratory and anatomopathologic findings of sheep affected by abomasum compaction. Clinically, the presence of a firm structure located in the abomasal region stands out. The hematology and ruminal fluid analyze revealed neutrofilia with regenerative left shift, hyperfibrinogenimia, fauna and flora impairment and chloride concentration of (39,33 mEq/L) respectively. Macroscopically, a distended and compacted abomasum was observed with the presence of type IV ulcers and diffuse serofibrinous peritonitis. These results confirm the severity of the abomasum compaction in small ruminants. Therefore, guidelines related to animal feed management practices, especially in times of drought are necessary to reduce the occurency of this disease.
