Abstract: To evaluate follicular dynamics, there was assessment of superovulatory response and in vivo embryo production in ewes treated with relatively smaller doses of exogenous pFSH than typically used in combination with a dose of eCG at the beginning of the gonadotropin treatment period. Santa Inês ewes (n?=?24) were randomly divided into three groups, based on mg dose of pFSH administered: G200 (n?=?8), G133 (n?=?8) and G100 (n?=?8) in eight decreasing doses at 12?-h intervals. All ewes were treated with 300 IU of eCG concomitantly starting with first pFSH administration. Ovulatory follicular dynamics and follicular wall vascularization (FWV) were evaluated using a B-mode and color Doppler ultrasonic machine, respectively. Superovulatory response and embryo production were evaluated 6 days after estrous detection. In the G200?group, the preovulatory follicle size (PFS) were less (P?

520 $aAbstract: To evaluate follicular dynamics, there was assessment of superovulatory response and in vivo embryo production in ewes treated with relatively smaller doses of exogenous pFSH than typically used in combination with a dose of eCG at the beginning of the gonadotropin treatment period. Santa Inês ewes (n?=?24) were randomly divided into three groups, based on mg dose of pFSH administered: G200 (n?=?8), G133 (n?=?8) and G100 (n?=?8) in eight decreasing doses at 12?-h intervals. All ewes were treated with 300 IU of eCG concomitantly starting with first pFSH administration. Ovulatory follicular dynamics and follicular wall vascularization (FWV) were evaluated using a B-mode and color Doppler ultrasonic machine, respectively. Superovulatory response and embryo production were evaluated 6 days after estrous detection. In the G200?group, the preovulatory follicle size (PFS) were less (P?<? 0.05), ovulation time later (P?<? 0.05), and PFS rate greater (P?<? 0.05); while in the G100 group ovulation rate, and number and percentage of unfertilized eggs were greater (P?<? 0.05) than in the G133 group (P?<? 0.05). Number and percentage of viable embryos were greater in the G200 and G100 compared to G133 group (P?<? 0.05). The dose of 100 mg of FSH was as efficacious as the traditional dose of 200 mg, in combination with a dose of eCG, for superovulatory response and viable embryo production but there was a greater percentage of unfertilized eggs with this treatment.
