Evaluation of effect of different estrus synchronization protocol on oxidative stress during summer season in cyclic Murrah Buffaloes

The present study was conducted with the objective to compare the estrus synchronization protocols on oxidative stress parameters in cyclic Murrah buffalo during summer season. Forty cyclic Murrah buffaloes were synchronized for estrus with standard Ovsynch (n=20) and Doublesynch protocol (n=20) and inseminated fixed time at 8 and 24hr of last GnRH injection. Blood samples were analyzed for the level of oxidative stress parameters. Overall, there was no significant difference (P<0.05) found between Ovsynch and Doublesynch treated buffaloes on the day of start of protocol and day of AI (Artificial Insemination) in overall MDA, GSH-Px and SOD concentration.
