摘要
5个杂交组合中 ,以德×本F1和德×细F1最好 ,这两个组合的周岁体重比本地羊高 10 5 和 10 4 ,达到显著水平 (P <0 0 5 )。寒×本F1较差 ,周岁重与本地羊相近 ,这是由于小尾寒羊放牧采食性较差之故。屠宰结果、产肉性能、羊肉品质及经济效益等项指标 ,亦以德×本F1和德×细F1组合最好 ,值得在生产中推广。而小尾寒羊具有繁殖率高的特点 ,这是肉羊生产中宝贵的特点 ,应在改善饲养管理和改放牧为舍饲的基础上积极引进利用。
In the five hybridized combinations,the best ones were the De Ben F\-1 and De Xi F\-1. The weight of the two combinations at one year old were 10 5 and 10 4 higher than native sheep (P<0 05). Han Ben F\-1 was not very satisfactory.The weight at one year old was similar to native sheep.The reason is that the XWH sheep don't have a good appetite to pastureland. About the result of slaughter, the property of meat production,the quality of mutton and the economic effect, et al.,in the five combinations, the De Ben F\-1 and the De Xi F\-1 were the best ones too. It is worth popularizing in production. And the XWH sheep have the trait of having higher rate of reproduction,which is the valuable of meat sheep. The sheep should be introduced actively on the basis of improving raising management and replacing pasturing with housing.
