Estrus Synchronization, Superovulation and Embryo Recovery in Egyptian Buffaloes
Abstract: SUMMARY
Several studies have been conducted on embryo transfer in buffaloes. The results re¬vealed that ovulation rate was lower than in cows. The present study was to investigate the best regimen for estrus synchronization and superovulation in buffaloes to increase the ovu¬lation rate and consequently the number of good embryos that can be transferred to the re¬cipient . Nine animals were randomly divided into three groups I, II and III. They were in¬jected (IM) with PGF2a analogue (cloprostenol) for induction of heat. Two IM injections of 500)Xg cloprostenol with eleven days interval were applied in groups I and II and 125 pg in¬tra vulval submucosal (IVSM) in group III. For superovulation induction, the animals in
all groups were injected with 3000 IU of eCG (IM) at day nine from 1st injection of PGF2cc. Additionally, buffaloes in group II and III were subjected to GnRH and hCG treatment 12 and 72 h after the onset of heat, respectively. The results of the current study demonstrated that IVSM cloprostenol injection significantly (P<0.05) increased the number of CL and de¬creased significantly (P<0.05) the number of anovulatory follicles than IM cloprostenol in¬jection. It can be concluded that the route of injection of PGF2oc and its dose have an es¬sential role for improving the ovulation rate . fertilization and consequently the transferable embryos.
