Ruminal Acidosis in Milk-Fed Calves

Lactic acidosis is a physiological condition characterized by low pH in body tissues and blood (acidosis) accompanied by the buildup of lactate, especially L-lactate, and is considered a distinct form of metabolic acidosis. Lactic acidosis is characterized by lactate levels >5 mmol/L and serum pH <7.35.

In domesticated ruminants, lactic acidosis may occur as a consequence of ingesting large amounts of grain, especially when the rumen population is poorly adapted to deal with grain.
