Superovulatory response to FSH and embryo recovery rate in Pandharpuri buffaloes (Bubalus bubalis).

The superovulatory responses using either 400 mg or 600 mg of FSH (Folltropin-V) in eight Pandharpuri buffaloes used repeatedly were studied. All buffaloes except one responded (minimum 2 CL / follicle) for superovulation in all seasons. Overall response (mean +/- SE) to superovulation was 61 ovulations (3.39 +/- 0.46), 21 follicles/cysts (1.40 +/- 0.41), 33 total embryos (1.94 +/- 0.39) and 24 viable embryo recoveries (1.41 +/- 0.32). The response was non-significantly higher in buffaloes injected with 400 mg (4.13 +/- 0.52-total ovulations) than 600 mg (2.80 +/- 0.64). Use of different bull semen had no significant difference in viable embryo recovery.
