萨能奶山羊杂交海南黑山羊效果分析

Hybrid Analysis between Hainan Black Goat and Saanen Dairy Goat

测定并比较海南黑山羊、萨能奶山羊及其F1B和F1W的体质量与体高、体斜长、胸深、胸宽、胸围、腰角宽等体尺指标,并对海南黑山羊与F1B和F1W的产奶性能做了比较。结果表明:F1B和F1W的体质量分别比海南黑山羊提高5.24%和29.80%,杂交效果显著;与海南黑山羊相比,F1B除体高外其余体尺指标均有不同程度提高;F1W各体尺指标均有较大幅度提高,除体斜长差异不显著外,其余各指标均达到了显著或极显著程度;F1W的产奶性能与海南黑山羊相比有较大幅度提高,杂交效果显著。

In this paper,the body weight,body height,oblique body length,chest depth,chest width,bust,and waist wide angle of the Hainan black goat,Saanen dairy goat and their offspring F1B,F1W were measured and compared.The milk production performance of the Hainan black goat,F1B and F1W were compared as well.The results showed that compared with the Hainan black goat,the body weight of F1B and F1W were increased 5.24% and 29.80% respectively,the body size traits of F1B increased in varying degrees except body height,the body size traits of F1W were substantial increased,most of indicators were significant or extremely significant difference excluding oblique body length,the milk production performance of F1W improved significantly.In summary,the hybridization effect was prominent.The results of this paper provide theoretical foundation and scientific basis for the rational development,utilization and crossbreeding of Hainan black goat.
