Abstract: This study was conducted to assess effects of different doses of pFSH on follicular recruitment, superovulatory response, ova/embryo recovery, and embryo yield in lactating ewes. Ewes (n?=?24) had a superovulation treatment regimen imposed. All ewes were implanted with a progesterone intravaginal device for 9 d, and administered either 100 (G-100) or 200 (G-200) mg pFSH, proportioned into six doses administered at 12-h intervals, starting 60?h before device removal. At 7 days subsequent to progesterone device removal, there were non-surgical embryo recoveries (NSER) from ewes having three or more corpora lutea. At the time of the first pFSH injection, number of antral follicles were similar (P?0.05) between ewes in the G-100 and G-200 group, however, there were more 3.1?4.0?mm follicles in ewes of the G-200 than G-100 group at the time of the second pFSH administration. Estrous response and CL number were less (P?0.05) in ewes of the G-100 (66.7 % and 2.6?±?0.7) than G-200 (91.7 % and 11.6?±?1.2) group. There were embryo collections from 100 % and 90.9 % of ewes in the G-100 and G-200 groups, respectively (P?>?0.05). Viable embryo numbers and ova/embryo recovery rate were greater (P?0.05) in ewes of the G-200 (6.9?±?1.1 and 67.8 %) than G-100 (1.0?±?0.5 and 27.6 %) group. A dose of 200 mg pFSH was more effective in inducing a superovulatory response and embryo yield after NSER in ewes, however, the 100 mg dose was insufficient for these purposes. |
