Oxidative Stress and Some Biochemical Parameters in Repeat Breeder Cows

18256

This study was carried out to investigate the changes in oxidative stress and some biochemical parameters in cows that were repeat breeder. A total of 40 Holstein cows were used in the study, 20 of which were repeat breeders between the ages of 3 and 8 and 20 of which were not fertilized. In all animals plasma malonaldehyde (MDA), catalase (CAT), glutathione (GSH), glutathione peroxidase (GSH-Px), serum triglyceride, cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), alkaline phosphatase aspartate aminotransferase (AST) levels were determined. As a result, MDA levels were found to be statistically higher (P 0.001), GSH (P 0.01), GSH-Px (P 0.001) and CAT (P 0.001) levels were lower in the control group than in the control group. In addition, triglyceride (P 0.05) and LDL (P 0.01) levels were higher in the control group than in the control group and HDL level was higher in the control group than in the control group (P 0.001). AST, ALT and cholesterol levels were not different between the groups. As a result, it was determined that oxidative stress and antioxidant enzyme levels were decreased in cows repeat breeder, and lipid profile was also different between groups.
