Acute carbohydrate engorgement in the Korean indigenous cattle, a case report

한우에서 급성탄수화물 과식증에 의한 폐사 증례

This case occurred following accidental consumptions of toxic levels of feedstuffs in the Korean indigenous cattle which were pregnant for 3-6 months. Grossly, poorly defined bluish coloration in the ventral sac of the rumen, reticulum and omasum was visible on the surface of the stomach. The severely affected ruminal walls were perforated and blood-tinged exudate was observed and death followed due to acute diffuse peritonitis. There were copious amount of porridgelike rumen contents, which has a distinct fermentative odor. The epithelia were easily wiped off and hyperemic in patch. Histopathologically, chemical rumenitis with neutrophilic infiltration and opportunistic fungal infection was evident in the mucosa and submucosa. Multifocal necrotic foci with fungal hyphae on the liver and severe congestion on the renal medulla were noted. There was no evidence of heavy metal and aflatoxin Bl in the suspected feedstuffs. This case was diagnosed as acute carbohydate engorgement in cattle.
