中国美利奴羊(新疆军垦型)品系间羊毛理化性能及性状相关分析

摘要

To study wool qualities among strains of Chinese Merino(Xinjiang Junken type). The physical and chemical properties of wool were assayed,the correlations between these properties and the main economic traits were analyzed in super fine wool strain,A strain,B strain,wool prolific strain, mutton prolific strain. The results showed that the average wool cluster length of A strain was the most length, the average fiber diameter of super fine wool strain was significantly lower than the other strains(P＜0.05) ,but the average wool curvature was significantly increased than the other strains (P＜0.05). The average wool yield of B strain was most, and the average wool yield of mutton prolific strain was significantly lower than the other strains(P＜0.05). The average clean wool glossiness of wool prolific strain was most, but the average clean wool glossiness among strains was no significantly more(P＞0.05). There vas significant negative correlation between fiber diameter and curvature(P＜0.01) ,it was significant positive correlation between fiber diameter and wool yield(P＜0.05) ,it was significant negative correlation between curvature and wool yield(P＜0.05) ,it was significant negative correlation between curvature and wool cluster length(P＜0.01), it was significant positive correlation between wool yield and wool cluster length(P＜0.01),it was significant positive correlation between wool cluster length and clean wool glossiness(P＜0. 05). The quality of wool of super fine wool strain was best comparing to other strains. It showed that wool characteristics of strains are same as breeding aims.%为研究中国美利奴羊(新疆军垦型)品系间的毛品质特点,以超细毛品系、A品系、B品系、毛用多胎品系和肉用多胎品系为试验对象,测定毛纤维的主要理化性能,分析各品系羊的毛纤维特点,并作相关分析.结果表明,A品系羊毛自然长度最长;超细毛品系羊毛纤维直径显著低于其它品系(P＜0.05),其羊毛卷曲度显著高于其它品系(P＜0.05);B品系污毛量最高,肉用多胎品系污毛量显著低于其它品系(P＜0.05).毛用多胎品系净毛率最高,但各品系间净毛率差异不显著(P＞0.05).相关分析结果表明,羊毛细度与卷曲度呈极显著负相关(P＜0.01),细度与污毛量呈显著正相关(P＜0.05);卷曲度与污毛量呈显著负相关(P＜0.05),卷曲度与自然长度呈极显著负相关(P＜0.01);污毛量与自然长度呈极显著正相关(P＜0.01);自然长度与净毛率呈显著正相关(P＜0.05).说明各品系羊的毛品质特点与培育目标一致,其中,超细毛品系羊毛综合品质优良.
