Physiological Effects of Acidosis on Feedlot Cattle

Abstract

The physiological effects of lactic acidosis in feedlot cattle may range from temporary inappetence to acute physiological alterations terminating in death. Physiopathology resulting from ruminal accumulation and subsequent absorption of lactic acid include rumen stasis, diarrhea and dehydration, systemic acidosis and, in acute forms of lactic acidosis, cardiovascular and respiratory failure. The rate of lactic acid absorption per unit time and not the total quantity absorbed appears to determine whether compensatory mechanisms remain functional and maintain the hydrogen ion concentration of body fluids within a compatible range.
