Resumo
We evaluated the effect of Recombinant Bovine Somatotropin (rbST) seven days before the start of thesynchronization protocol on pregnancy rate in goats. Were used 101 females without defined breed in semiintensivesystem, randomly divided into two groups. Seven days before the start of estrus synchronization, G1 (n= 49) received 125 mg of rbST, IM, and G2 (n = 52) physiological saline, subcutaneously. In D0, the groupsreceived 1 mL of BE, IM, and were synchronized with intravaginal sponges impregnated with 60 mg ofmedroxyprogesterone for 11 days. In D9, they received 300 IU of eCG and 75 µg of PGF2α. On D11, thesponges were removed, we performed IATF 36 and 48 hours later, transcervically. It was used pool of AngloNubians semen. Gestational diagnosis was performed 30 days later. A single dose administration of rbST, sevendays before estrus synchronization, did not increase the pregnancy rate.(AU)
