【摘要】：论文分析了阿勒泰羊毛绒品质性状之间的相关关系,为有效指导提高阿勒泰羊的生产性能提供科学依据。对313只个体的毛样进行绒毛纤维直径、直径标准差、直径变异系数、洗净率、含绒率、绒毛白度、光泽度、黄度、舒适度等测定;采用SAS9.1软件分析年龄、羊场及其互作效应对阿勒泰羊绒毛性状的影响,进而明确各性状间的相关关系。结果表明:年龄因素对阿勒泰羊绒毛平均纤维直径性状影响极显著(P0.01),对纤维直径变异系数、舒适度影响显著(P0.05);羊场对绒毛直径变异系数、白度、光泽度的影响显著(P0.05)。绒毛纤维直径与直径标准差呈极显著正相关(P0.01),与洗净率、黄度呈显著正相关(P0.05),与舒适度呈极显著负相关(P0.01)相关系数达到-0.906,与含绒率呈显著负相关(P0.05),与直径变异系数、白度、光泽度之间没有显著相关(P0.05);直径标准差与直径变异系数呈极显著正相关(P0.01),与舒适度呈极显著负相关(P0.01),与黄度呈显著负相关(P0.05);直径变异系数与洗净率、黄度、舒适度呈极显著负相关(P0.01);洗净率与含绒率呈极显著负相关(P0.01);绒毛白度与光泽度大小呈极显著正相关(P0.01)相关系数达到0.995,与黄度呈极显著负相关(P0.01);绒毛光泽度与黄度呈极显著负相关(P0.01)。本研究的结果为阿勒泰羊毛绒品质评定以及优良种畜选育工作提供可靠依据。
[Abstract]:The correlation between wool quality traits of Altay sheep was analyzed in order to provide scientific basis for improving the production performance of Altay sheep. The fiber diameter, diameter standard deviation, diameter coefficient of variation of the wool samples of 313 individuals were studied. SAS9.1 software was used to analyze the effects of age, sheep farm and their interaction on the cashmere traits of Altay, including washing rate, cashmere content, fluff whiteness, gloss, yellowness, comfort and so on, using SAS9.1 software to analyze the effects of age, sheep farm and their interaction on the cashmere properties of Altay. The results showed that age factors had a significant effect on the average fiber diameter of Altay cashmere, and had a significant effect on the coefficient of variation of fiber diameter and comfort, and on the coefficient of variation of wool diameter and the whiteness of sheep farm. The effect of gloss was significant (P0.05N). There was a significant positive correlation between fiber diameter and diameter standard deviation (P0.01A), and there was a significant correlation between the fiber diameter and washing efficiency. There was a significant positive correlation between yellowness (P0.05A), a very significant negative correlation with comfort (P0.01) (-0.906), a significant negative correlation with velvet content (P0.05), and a significant correlation with diameter coefficient of variation (DVA) and whiteness. There was no significant correlation between glossiness (P 0.05), diameter standard deviation and diameter coefficient of variation (P 0.01), significant negative correlation with comfort (P 0.01), and significant negative correlation with yellowness (P 0.05), diameter coefficient of variation and washing rate, yellowness. There was a significant negative correlation between the degree of comfort (P0.01A), a very significant negative correlation between the washing rate and the velvet content (P0.01a), a very significant positive correlation between the whiteness of the villi and the luster size (P0.01). The correlation coefficient was 0.995. there was a very significant negative correlation between the luster and the yellowness of the villi, and the correlation between the luster and the yellowness of the villi was extremely significant. The results provided a reliable basis for the evaluation of wool quality and the breeding of fine breeds of Altay sheep.
