This study checked the effect of hCG on pregnancy rate of recipient goats. Multiparous acyclic dairy goats (Alpine/Saanen) from second to third parity order (n=40) were subjected to synchronous estrus induction by use of intravaginal sponges (60 mg of medroxyprogesterone acetate; Progespon®, Zoetis, São Paulo, Brazil) for six days plus 200 IU of equine chorionic gonadotropin (eCG; Sincro-eCG 6000®; Ouro Fino, Cravinhos, Brazil) and 131.5 μg of cloprostenol (Sincrocio®, Ouro Fino, Cravinhos, Brazil) i.m. 24 h before sponge removal. Estrus was monitored twice daily with fertile males (D0 = Day of onset of estrus). Overall pregnancy rate was 63.0% (17/27), being 58.3% (7/12) and 66.7% (10/15) for G-Control and G-hCG, respectively (P > 0.05). Preliminary results showed an interesting pregnancy rate obtained by non-surgical technique while hCG positive effect remained to be checked in large trials in dairy goats.
