Abstract: The females were exposed to the male effect for 45 days for 80 minutes twice a day. Reproductive parameters recorded were: percentage of females in estrus, onset of estrus, rate of return to estrus and rate of fertility. Data were analyzed using descriptive statistic. Of the females submitted to male effect 100% they had revealed estrus clinical. With respect to clinical signs of estrus, it was observed that 69% had estrus between 7-10 days after introduction of the ruffian in the flock. The rate of return to estrus was 25% in the interval of 8 to 24 days. The fertility rate of the herd was 93.75%. Therefore it is concluded that the male effect showed satisfactory results for female goats bred in agrosilvopasture system.  aCaprino1 aBRITO, I. F.1 aSOUSA, S. D.1 aABREU, D.
