Ten nonlactating buffalo were superovulated with 3000 IU PMSG. Luteolysis was induced with 500 microg Cloprostenol (PG) 60 and 72 h after PMSG. Five buffalo were alloted for natural mating and five were bred by artificial insemination 60 and 84 h after the first PG treatment. Since four buffalo developed pyometra, only 6 of 10 underwent embryo collection(More)
