Abstract A089. Edição dos Proceedings of the 32nd Annual Meeting of the Brazilian Embryo Technology Society (SBTE); Florianópolis, SC, Brazil, August 16th to 18th, 2018.c2018  aThis 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.  aAnimal reproduction  aEmbryo transfer  aEwes  aMedroxyprogesterone  aSheep  aSuperovulation  aSynthetic progestogens  aOvino  aProgesterona  aReprodução Animal  aSuperovulação  aTransferência de Embrião  aFSH  aSuperovulated females  aTranscervical embryo1 aALVES, N.
