摘　　要：用辽宁绒山羊改良引进的内蒙古白绒山羊与甘南当地藏山羊,结果表明:辽蒙藏杂交F1代绒山羊,在初生、3月龄、6月龄、12月龄各个时期,其体重、体高、体长、胸围与对照组(蒙藏山羊杂交后代)相比,公羊除初生和3月龄羔羊的体长、12月龄胸围差异不显著外(P(0.05),其它均极显著的高于对照组;母羊的3月龄、12月龄体重与对照组差异极显著(P<0.01),初生、6月龄体重差异显著(0.01(P(0.05),初生、3月龄、6月龄体高、胸围及6月龄体长与对照组差异极显著(P<0.01),公、母羊绒细度、长度、单纤维断裂强力、单纤维断裂伸长率等指标差异不显著(P(0.05),含绒率和产绒量差异极显著(P(0.01)。杂交F1代羊杂交优势明显,效果显著。Using Plastic Straw Semen of Liaoning Cashmere Goats crossbreeding mongolian - tibetan Cashmere Goats in Gannan, we find outcome that the weight, body high,body length, chest measurement of hybrid progeny on primary lamp, 3 -month- old, 6 - month- old,12- month- old trast mongolian- tibetan Cashmere Goats the significant level is well,tbe cashnere production performance of Hybrid progeny is also very well, the rate and production of Cashmere are significant, other index is no - significant, all the re- sults introdue that the every index about hybrid progeny of Liaoning - mongolian - tibetan Cashmere Goats is excellent.
