贵州黑马羊的选育

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40.08kg±7.73 kg3、4.90 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 kg3、2.16 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(P0.01)。无角对有角是显性,山羊间性与无角存在连锁关系。

The Breeding of Guizhou Black Horse Goat

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.
