This investigation was undertaken to determine the relationship of abomasal displacement and tatty liver syndrome in dairy cows. Twelve cows with abomasal displacement (7 LDA, 5 RDA) and 10 healthy cows (after calving) has been used as material. Blood and liver biopsy samples were taken from healthy cows and cows with abomasal displacement. Surgery was performed on cows with abomasal displacement and 9 ol 12 cows with abomasal displacement was recovered, but 3 of them was not healed. The differencies in aspartate aminotransferase (AST), glucose and Mg concentrations of healthy cows compared to cows with abomasal displacement were found to be significant (p<0.01). Thus, the differencies in alanine aminotransferase (ALT). albumin(Alb) and Ca levels ol healthy cows compared to cows with abomasal displacement were found to be significant (p<0.05). But, there was no significant in alkaline phospahatase (ALP), cholesterol, triglyceride, total bilirubin, TP and P concentrations between healthy cows and cows with abomasal displacement In 10 of all the cases, various degree fat infiltration ot liver was observed But. two cases has not shown any fat inflation of liver.
