Paradoxic aciduria in bovine metabolic alkalosis.

Cows with metabolic alkalosis secondary to abomasal displacement and other abomasal disorders were often found to excrete acidic urine. This paradoxic aciduria contradictsthe classical view that the pH of the urine may be used to estimate the acid-base status of the body. Data from bovine clinical patients with metabolic alkalosis, serum electrolyte changes, and paradoxic aciduria suggested that the balance of sodium potassium, and chloride in the body places limits on the kidneys' ability to regulate the acid-basebalance.
