Liver function in dairy cows with abomasal displacement

The aim of this study was to establish the changes that [nay occur in liver function in dairy cows with abomasal displacement. The liver biopsies from cows with abomasal displacement had 31.5+/-6.1 % fat infiltration. Some chemical parameters (bile acid, glucose, total protein, urea, albumin, globulin, total bilirubin, direct bilirubin, indirect bilirubin, AST, ALT, GGT, CK, triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol) were measured. Serum AST (p<0.01) and GGT (p<0.001) levels were significantly increased, and HDL-cholesterol (p<0.001) significantly decreased in cows with abomasal displacement compared to healthy cows. There were significant alterations in urea, total protein, albumin, total cholesterol, total bilirubin and indirect bilirubin concentrations, but they were within normal range limits in the same animals. In conclusion, GGT and AST concentrations, and liver biopsy seem to be helpful in the assessment of liver function in cows with abomasal displacement.
