阿勒泰羊绒毛品质性状分析
Quality Analysis of Altay Sheep Down
摘要
Abstract
The present study investigated the correlation among different phenotypic characters of sheep down in Altay sheep to provide a scientific basis for effective guidance to improve production performance of Altay sheep.313 Altay sheep were selected to measure the mean fiber diameter (MFD, μm), diameter standard deviation(DSD, μm), diameter variable coefficient (DVC,%), scoured yield(SY,%), sheep down content (SDC,%), the whiteness of sheep down (Wht), lightness(L), yellowness (YL), comfort(CF), and then analyzed the effect of age, farm and their interaction effects on quality of sheep down in Altay Sheep and then investigated the correlation among different phenotypic characters of sheep down by SAS9.1 software.The results showed that age had significant effects on MFD(P<0.01), DVC and CF (P<0.05), and farms had significant effects on DVC, Wht and L (P<0.05).MFD was significantly positively correlated with DSD(P<0.01), SY and YL(P<0.05), and negatively correlated with CF(r=-0.906,P<0.01) and DHC(P<0.05), there was no significant correlation between MFD with DVC, Wht and L(P>0.05);.DSD was significantly positively correlated with DVC (P<0.01), and significantly negatively correlated with CF(P<0.01) and YL(P<0.05).DVC was significantly negatively correlated with SY, YL and CF(P<0.01).Wht was significantly positively correlated with L(r=0.995,P<0.05), and negatively correlated with YL(P<0.01).SY was significantly negatively correlated with DHC(P<0.01).L was significantly negatively correlated with YL(P<0.01).In conclusion, the study provides a reliable basis for the quality assessment of Altay sheep down and fine-breed livestock breeding.关键词
