| This study assessed two superovulatory treatments and the feasibility of transcervical embryo recovery in Lacaune ewes. Ewes (n=23) received medroxyprogesterone acetate sponges (60mg, Progespon®, Syntex, (Prolise®, Tecnopec, São Paulo, Brazil) 24 h before sponge removal and were superovulated with 133 mg of porcine FSH i.m. (Folltropin®-V; Bioniche Animal Health, Belleville, Canada) in six decreasing doses (twice daily) at 60 h before sponge removal, under a crossover design. In conclusion, both treatments showed high variability in ovulatory response which might reduce the embryo yield average from donors. The protocol for cervical relaxation allowed the transcervical embryo recovery in high percentage of Lacaune ewes. |

| The present study tested the hypothesis that hCG and pFSH stimulate the follicular development and consequently corpora lutea, in a manner equivalent to those induced by eCG in goat. Eighty-five Toggenburg goats, during the seasonal transition period (December, 21ºS), underwent a short-duration estrus induction/synchronization protocol with a sponge impregnated with medroxyprogesterone acetate (60 mg MAP, 6 days). In conclusion, the use of hCG and pFSH in protocol of estrus induction/synchronization in goats induces equivalent luteal dynamics and conception rate, being substitutes for eCG. |
