Conteúdo: | Reproduction and production levels are low under traditional goat management systems in northeast Brazil. A two-year experiment was conducted simulating the producers management practices to evaluate the performance of SRD goats. The does were exposed for breeding continuosly throughout the two years of the experimental period. The does kidded throughout the year. The overall fertility (percent of does kidding of total does exposed to male) was 78.5 percent with two peaks in February and October. The overall incidence of abortion was 24.7 percent with a peak in July. Thirty-two percent of the does kidded twice in one year and an additional 5.2 percent kidded three times in two years. From 85 kiddings recorded, 54.1, 37.6 and 7.1 percent were singles, twins, triplets and undertermined, respectively. Prolificacy was 1.3 and the overall average kidding interval was 282.5 days. From 113 kids born, 68.1 percent died before weaning at 112 days, with 60.9, 71.9 and 100 percent mortality for singles, twins and triplets, respectively. The postpartum period for 19 does producing singles and 14 does producing twins was 93.2 and 104.9 days, respectively.
