| 摘 要： | 按照不同的年龄阶段、不同性别的绒山羊,进行产绒量、体重的现场测定,采取相同羊号的毛样,利用奥达2.0光学纤维直径分析仪,对羊毛细度进行测定,分析南疆绒山羊主要经济表型性状的相关性。结果表明:成年母羊取样56只,绒产量与细度呈现正相关差异极显著(P<0.01);体重与细度呈现正相关,差异不显著;体重与绒产量呈现负相关差异不显著。育成母羊取样81只,产绒量与细度呈现正相关,差异显著(P<0.05);体重与细度呈现正相关,绒产量与体重呈现正相关,差异都不显著。2~3周岁公羊取样22只,绒产量与细度呈现正相关,差异显著(P<0.05),体重与细度呈现正相关,绒产量与体重呈现正相关,差异都不显著。4~6周岁公羊取样21只,绒产量与细度呈现弱的正相关,体重与细度呈现负相关,绒产量与体重呈现正相关,差异都不显著。

| Abstract: | According to the age and gender,measure their cashmere production and their body weight.Then analyze correlation of all traits above.The results showed : for 56Adult ewes,there is a positive correlation(P<0.01)between Cashmere production and fineness,positive correlation between Weight and fineness,a negative correlation between Weight and cashmere production;for 81 Breeding ewes samples,showing weak positive correlation(P<0.05)between Cashmere production and fineness,positive correlation between body weigh... |
