Levels of antioxidant substances, acute phase response and lipid peroxidation in the left and right abomasum displacement in cows

The aim of the present study was to assess metabolic changes occurring in Holstein cows with left or right abomasal displacement. Total sialic acid (TSA) values of the left abomasal displacement (LDA) group were elevated significantly (p<0.0001) as compared to the controls. In the LDA group, serum ceruloplasmin (CPN) and aspartate transaminase (AST) levels were increased significantly (p<0.0001) as well. Compared to the control group, serum glutathione (GSH) level was decreased significantly in both LDA and right abomasal displacement (RDA) groups (p<0.0001). Among the clinical examination parameters, rumen contraction rates were decreased in both LDA and RDA groups significantly (p
