abstract
The reproductive efficiency of the buffalo is lower than that of cattle. Both infectious and non infectious factors contribute to the long calving, especially because of anoestrus, repeat breeding and abortion. Pluriparous Jaffarabadi buffaloes (12) were divided into two groups. Control group was inseminated twice at 24 h interval during natural estrus with good quality frozen thawed semen. Whereas treatment group buffaloes were treated with ovsynch protocol. Treatment group were achieved significant higher pregnancy rate when compare to control group.
