A.  aPuberty in four genotypes of female goats in Northeast Brazil.  c1990  aAbstract: This experiment was carried out with 99 female kids from four native brceds (Canind& Marota, Moxotó, and Repartida, raised on native pasture at Lhe l3razilian National (loat Research Center, Ceará State, Northeast Brazil. Body weight of the animais were taken at birth, and at four-week intervais until each female kid showed the first puberal estrus. Between 40-60 hours after puberal estrus was detected using teaser bucks, the ovaries of each female kid were observed by laparotomy to determine the number of corpora albicantia and/or corpora hemorrhagica, as an estimate of the occurrence and rate of prepuberal and puberal ovulation, respectively. The overail mean age and live body weight at puberty was 3616±69 days and 12.6±0.2 kg, respectively. I3reed or type of birth did not affect sigrnficaniiy (P&gt0.05) the age and weight at puberty. The ovulation rate at prepuberal period and at puberal estrus was 1.00 and 1.04, respcctively (P&gt0.05). Forty percent of the female kids ovulated prior to puberal estrus and 100% ovulated at puberal estrus. Ovulation occurred more frequentely m the right than iii the Ieft ovary at prepuberal (P&lt0.01) and puberal (P&lt0.05) respectively. [Puberdade em fêmeas caprinas de quatro raças no Nordeste do Brasil]. Resumo: Este trabalho foi conduzido com 99 cabritas, 11 da raca Caninde, 13 Marota, 64 Moxoto e 11 Repartida, mantidas em pastagem nativa, na EMBRAPA.CNPC. As cabritas foram pesadas ao nascer e, a cada quatro semanas ate o primeiro estro clinico (puberdade). Entre 40-60 horas apos o inicio do estro a cabrita foi submetida a laparatomia com o objetivo de se avaliar a funcao ovariana, quantificando-se a ocorrencia e a taxa de ovulacao nos periodos pre-puberal e puberal. A idade e o peso corporal a puberdade foram 363,6 mais/menos 6,9 dias e 12,6 mais ou menos 0,2 Kg, respectivamente. A raca e o tipo de parto nao afetaram significativamente (P&gt0,05) a idade e o peso a puberdade. As taxas medias de ovulacao, no periodo pre-puberal e a puberdade, foram 1,00 e 1,04, respectivamente (P&gt0,05). Aproximadamente 40,0% das cabritas tinham ovulado antes de apresentarem o primeiro estro clinico, enquanto 100,0% delas ovularam a puberdade. A ovulacao ocorreu com maior frequencia no ovario direito do que no esquerdo, no periodo pre-puberal (P&lt0,01) e a puberdade (P&lt0,05).  aBrazil  aGoats  aOvulation  apuberty  aRangelands  aSexual maturity  aCaprino  aEspécie nativa  aMaturidade sexual  aOvulação  aPastagem nativa  aFemale animals  aNative species  aNortheast  aPuberdade  aRaça Canindé  aRaça Marota  aRaça Moxotó  aRaça Repartida1 aFIGUEIREDO, E.
