Data from a research station in the central African country of Rwanda relating to purebred Small East African (SEA) goats, Anglo-Nubian x SEA and Alpine x SEA goats were analysed. Both SEA (598 days) and Alpine crosses (557 days) were younger at first kidding than the Anglo-Nubian crosses (766 days). There were no differences among genotypes in kidding interval which averaged 343 days nor did they differ in litter size (1.75). Mortality to 150 days (17.8%) was significantly higher in the Anglo-Nubian crosses than in Alpine crosses with the SEA being intermediate and not differing from either. Birth weights of individual kids were significantly lighter for purebred SEA (2.35 kg) than for Anglo-Nubians (2.68 kg) which were significantly lighter than the Alpine crosses (2.89 kg). Total litter weight at 150 days was significantly lower for SEA (14.5 kg) than for Alpine (18.8 kg), the Anglo-Nubian (16.9 kg) not differing significantly from either. Female postpartum weights differed significantly among genotypes, SEA being lightest (37.5 kg), Alpine crosses (42.1 kg) intermediate and Anglo-Nubian crosses (51.4 kg) heaviest. Productivity indices (total weight of live young at 150 days per kg of dam per year) averaged 442 g and did not differ among genotypes.
对位于非洲中部国家卢旺达的一个研究站提供的有关纯种东非小山羊（SEA）、安哥拉努比亚×SEA和阿尔卑斯×SEA山羊的数据进行了分析。SEA山羊（598天）和阿尔卑斯杂交山羊（557天）首次产羔的年龄均比安哥拉努比亚杂交山羊（766天）小。不同基因型之间的产羔间隔没有差异，平均为343天，产仔数也没有差异（1.75只）。安哥拉努比亚杂交山羊150日龄前的死亡率（17.8%）显著高于阿尔卑斯杂交山羊，SEA山羊居中，与两者均无差异。纯种SEA山羊个体羔羊的出生体重（2.35千克）显著轻于安哥拉努比亚山羊（2.68千克），而安哥拉努比亚山羊又显著轻于阿尔卑斯杂交山羊（2.89千克）。SEA山羊150日龄时的总窝重（14.5千克）显著低于阿尔卑斯山羊（18.8千克），安哥拉努比亚山羊（16.9千克）与两者均无显著差异。不同基因型的母羊产后体重差异显著，SEA山羊最轻（37.5千克），阿尔卑斯杂交山羊（42.1千克）居中，安哥拉努比亚杂交山羊最重（51.4千克）。生产力指数（150日龄时活仔的总重量/每年每千克母羊体重）平均为442克，不同基因型之间没有差异。
