Physiological, biochemical and histopathological effects of fermentative acidosis in ruminant production: a minimal review

Abstract

Rumen acidosis is increasingly recognized as a significant disorder in ruminants that increases the morbidity and mortality of animals, especially for dairy cattle and sheep. Acidosis is not just D-lactate which disturbs the acid-base status and the severity of acidosis is related to many factors and not only due to the level of lactic acid production, resulting in difficulties in diagnosing acidosis. Therefore, an understanding of the physiological, biochemical, and histopathological effects of rumen acidosis is fundamental for developing effective methods of prevention and treatment of fermentative acidosis. The present review evaluates the physiology, biochemistry, and pathophysiology of fermentative acidosis as well as gives a conclusion and look-forward. The information will benefit the health and welfare of ruminants and contribute to modern systems of ruminant production.
