[Acute acidosis in a bovine].

A case of acute acidosis due to over-ingestion of maizemeal is reported. The cow was in sternal recumbancy, unable to rise and showed signs of severe dehydration, metabolic acidosis and rumen stasis. Examination of rumen contents revealed changes consistent with those of lactic acidosis. Treatment included correction of the metabolic acidosis, restoration of intravascular volume, manipulation of rumen contents including rumen lavage and other supportive treatment. Some pathophysiological aspects and the need for a systematic and vigorous treatment regime are discussed.
