If electrolyte levels are measured affected animals develop a hypochloraemia due to reduced outflow of ingesta from the abomasum combined with contined secretion of hydrochloric acid into the abomasum.

If electrolyte levels and blood gas are measured affected animals develop a hypochloraemia and metabolic alkalosis due to reduced outflow of ingesta from the abomasum combined with contined secretion of hydrochloric acid into the abomasum.
