摘要: 试验采取在农家组建核心群、基础群的开放式选育路线,制订初步淘汰标准、综合选择指数,指导整群淘汰、选种选配。结果发现,选育后核心群周岁公母羊体重分别为29.77 kg±5.51 kg、25.18 kg±5.67 kg,成年公母羊体重分别为40.08 kg±7.73 kg、34.90 kg±6.56 kg;选育后基础群周岁公母羊体重分别为26.59 kg±3.68 kg、24.09 kg±4.60 kg,成年公母羊体重分别为35.33 kg±4.09 kg、32.16 kg±6.83 kg;产羔率达152.33%。经t检验,选育后核心群周岁公母羊、基础群周岁公母羊、成年公母羊平均体重极显著高于选育前的平均体重(P<0.01)。无角对有角是显性,山羊间性与无角存在连锁关系。

Abstract: To take home at the farmers formed the core group, the basis of the open cluster selection methods, the development of basic elimination criteria, a comprehensive selection index to guide finishing goats and eliminated, selection option.The results showed that the core group of age body weight of male and female goats were 29.77 kg±5.51 kg, 25.18 kg±5.67 kg, weight of adult male and female goats were 40.08 kg±7.73 kg, 34.90 kg±6.56 kg; based group of age body weight of male and female goats were 26.59 kg±3.68 kg, 24.09 kg±4.60 kg, weight of adult male and female goats were 35.33 kg±4.09 kg, 32.16 kg±6.83 kg; lambing rate was 152.33%. The significance test, breeding, after the core group, the basis of age group, the average weight of adult ewes was significantly higher than the average weight of pre-selection(P<0.01). No angle on a corner was the dominant, goats angle between the sexual and the non-existence of linkage.
