The Effects of Mating in Rams on Blood Malondialdehyde and Some Antioxidants

The aim of the study was to investigate the malondialdehyde (MDA), glutathione (GSH) levels and glutathione peroxidase (GSH‐Px), catalase (CAT) activities in the blood on pre‐, during and post‐mating days in rams (2 Chios, 2 Awassi and 2 Ost‐Friz). Blood samples were collected from the jugular vein on 15 day earlier, on the day of mating and 15th day after mating. The MDA level in the plasma, GSH level and GSH‐Px, CAT activities in the erythrocytes were measured. No statistically significant difference was found for antioxidant parameters measured on pre‐, during and post‐mating days. However, MDA levels were slightly increased during mating. In conclusion, it was found that mating in rams had no influence on blood MDA level and the antioxidant parameters measured herein.
