    Background Blood serum and peritoneal fluid acute-phase proteins, oxidative stress indicators, and some enzymes could be used for evaluation of abomasal tissue damage because of displacement in displaced abomasum (DA) cases. Objectives The aim of this study was to investigate the concentrations of acute-phase proteins, oxidative stress indicators, and activities of enzymes in blood serum and peritoneal fluid in cattle with right displaced abomasum (RDA) and left displaced abomasum (LDA) and in healthy cows. Animals A total of 60 Holstein Friesian cows in early lactation were used, 31 with left and 9 with right displaced abomasum without volvulus diagnosis and no other postpartum disease, and 20 healthy cows as a control. Materials and Methods DA diagnosis in dairy cows consisted of physical examination, laboratory, and specific DA tests. Acute-phase proteins, oxidative stress indicators, and enzyme activities were measured in blood serum and peritoneal fluid. Results In the RDA group, serum haptoglobin (HPG), serum amyloid A (SAA), malondialdehyde (MDA), adenosine deaminase (ADA), myeleperoxidase (MPO), aspartate aminotransferase (AST), creatine kinase (CK, creatine kinaseMB (CK-MB), and gamma-glutamyl transferase (GGT) activity increased significantly, and serum HPG, MDA, ADA, and AST concentrations increased significantly in the LDA group (P < .05). Peritoneal fluid HPG, MDA, ADA, MPO, ALP, GGT, and LDH concentrations increased significantly, whereas NO concentrations reduced significantly in the RDA group, and HPG, MDA, ADA, and TP concentrations increased significantly, whereas concentrations of NO reduced significantly in the LDA group (P < .05). Conclusions and Clinical Importance There are acute-phase responses, oxidative stress, and abomasal tissue damage because of displacement in DA cases. Especially, HPG, MDA, ADA, and MPO concentrations can provide specific information to help in understanding these changes.
