Blood Chemistry Including Ketone Bodies before and after Surgical Operation in Cows with Abomasal Displacement

Abstract

Blood chemical values including ketone bodies were measured before and after surgical operation in 6 each Holstein-Friesian cows with abomasal displacement. The increased and decrecased levels of aspartate aminotransferase (AST), non-esterified fatty acid (NEFA) and ketone bodies (3-hydroxybutyric acid and acetoacetic acid) were observed before and after operation, respectively, suggesting that the onset of abomasal displacement was closely related to the increase of serum ketone bodies and NEFA. Total cholesterol level was unchanged before and after operation, and no definite tendency could be found in γ-glutamyl transpeptidase levels.
