The pre- and postoperative course of acid-base parameters and electrolyte concentrations in urine and blood was studied in 67 cows affected with left- or right- sided abomasal displacement. Paradoxic aciduria was detected in 21 of 37 cattle with preoperative alcalosis. The validity of serum electrolyte determinations for the detection of electrolyte disturbances is limited. The evaluated parameters returned to normal in most of the animals within the following intervals post-op.: 1. day: blood gas parameters 2 days: hematocrit 3 days: general condition, serum chloride and serum sodium concentrations 4 days: urine-pH, net acid-base excretion, urine chloride and serum potassium concentrations. Urine-pH and net acid-base excretion increases only after serum electrolyte levels return to normal.
