Abstract: Repeat breeding is very important infertility problem in Surti buffaloes caused by various factors which causes low milk production and reduced number of calves per animal leading to economic losses at farmer and industry levels. This study was conducted to study the oxidative stress which is an important factor of repeat breeding in Surti buffalo. The blood samples were collected at Livestock Research Station, NAU, Navsari, Gujarat and analyzed for glucose, BUN, Mg2+, Na+, K+, Ca2+ and Cl- in the control and repeat breeder Surti buffalo. These samples were analyzed for various parameters of oxidant/antioxidant status in repeat breeder buffalo. The level of malondialdehyde was significantly increased (p<0.05) as compared to normal Surti bufaalo (2.40±0.16 vs. 4.52±0.20). Nitric oxide level was also increased significantly in repeat breeder buffalo as compared to normal buffalo (24.76±1.01 vs. 42.01±0.58). Level of blood urea nitrogen (BUN) was significantly higher in repeat breeder buffalo as compared to normal. Moreover, the level of Glucose, SOD, catalase, glutathione and total oxidant capacity were significantly decreased in the repeat breeder Surti buffalo (p<0.05). Therefore, the study concluded that repeat breeder Surti buffalo is under oxidative stress and should be provided adequate amount of antioxidants and minerals in their food.
