Treatment of summer anestrous buffalo (bubalus bubalis) with progesterone releasing intravaginal device plus pregnant mare serum go nadotropin.
Three experiments were conducted to treat forty-two summer-anestrous buffalo at three different villages. In all the experiments animals were randomly divided into two groups. One group was treated with a progesterone releasing intravaginal device (PRID) plus 800 IU pregnant mare serum gonadotropin (PMSG) at the time of PRID removal. The second group was retained as untreated control animals. All the treated animals were clinically examined and inseminated twice 48 and 72 h post treatment. Ovulation and fertility rates at induced estrus were 88, 90 and 100% and 50, 60 and 50% during Experiments I, II and III, respectively. None of the controls exhibited estrus during the course of the study.
