摘要
本试验用辽宁绒山羊与新疆母山羊进行杂交改良,经过9年多的工作,取得了大量数据,证明杂交改良效果好,改良羊与父母本的适应性一样强,杂交羊的产绒量有了明显的提高。杂交1代、2代、3代周岁母羊产绒量分别比当地山羊高76.22克、114.65克、131.05克;分别提高53.99％、81.21％、92.82％,各组平均抓绒量间有极显著的差异(P<0.01)。这项研究结果对提高我区山羊生产将会起到积极作用,具有一定的社会效益和经济效益。
Experiments have been carried out for 9 years to improve Xinjiang goat using Liaoning cashmere goat. Results showed that the adaptability was good, the down production of F1, F2, F3 was increased 76.22, 114.65, 131.05 grams respectively, i.e.increasing 53.99,81.21 and 92.82% respectively.
