Descripción

This study evaluated the efficiency of non-surgical embryo recovery (NSER) with cervical relaxation protocol using different doses of estradiol benzoate (EB) in ewes. A total of 36 pluriparous Dorper ewes received intravaginal sponges containing 60 mg of medroxyprogesterone acetate (Progespon®, Zoetis, Brazil) for 9 d plus an injection of 300 IU of eCG (Novormon®, Zoetis, Brazil) i.m. 24 h before sponge removal.
