Conteúdo:  Abstract: The reproductive performance of 50 adult SRD does maintained in native caatinga pasture at a stocking rate of 1 to 1.5 ha/head/year was evaluated. Two bucks were used in natural matings from September 1978 until December 1980. A total of 93 kiddings and 28 abortions occurred. Three pregnancies occurred before initiation of the experiment. From the 90 parturitions, 57.7%, 35.6%, 1.1 % and 5.6% bore singles, twins, triplets and undetermined, respectively. The flock showed an overall prolificacy of 1.38. From the initial fIock, 15(30%), 28(56%), 5(10%) and 2(4%) does presented one, two, three and zero kiddings, respectively during the period of study. Neither gestation length nor kidding interval were influenced by type of birth. Length of open period was influenced by season of the year when data were classified by season and kidding status at the open period. Combination of kidding type at previous and following kiddings showed a significant influence (P < 0.05) on the length of the open period. AnimaIs which kidded first singles and then singles or twins showed a shorter open period than animaIs which firstly kidded twins and then aborted at the following pregnant (109 Ys 188 days). The peak of kid mortality occurred between 7 and 112 days of age. Kid mortality appears not to be influenced by sex or type of birth. Overall kid mortality was 76%. The age at dead of kids was influenced by season and sex as weil as by their interaction. Males bom during the rainyseason... Mostrar Tudo
