Often a severe ketosis is present resulting in raised blood butyrate.

Often a severe ketosis is present resulting in raised blood beta-hydroxybutyrate.

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 continued secretion of hydrochloric acid into the abomasum.

Hypokalaemia also develops due to the alkalosis which drives potassium into cells combined with a reduced intake due to anorexia.

Hypokalaemia also develops due to alkalosis (or hyperinsulinaemia in certain cases), which drives potassium into cells combined with a reduced intake due to anorexia.
