In this study, SPSS software (Version 10.0) was used to analyze wool physical property of small tail han sheep,long tail han sheep,and Yuxi fat-tailed sheep.The results showed that the weight percentages of down hair for small tail han sheep,long tail han sheep, and Yuxi fattailed sheep were (74.88±12.12) ％, (85.05± 13.93)％ and (64.32±8.87) ％ respectively,giving a significant different levels (P＜0.05).The percentage of downhair for these three sheep breeds was (82.36±2.97)％, (89.18±8.18)％ and (80.12±4.45)％ respectively,giving a significant different level (P＜0.05).Additionally, significant difference of weight percentage of medullated fibers,percentage of medullated fibers, hair plait length, down hair strentched length and fineness of down hair among the three sheep breeds was also found (P＜0.05).Small tail han sheep has longer hair plait length and more fine fineness than other two sheep breeds,while long tail han sheep has higher percentage of down hair.%利用SPSS10.0软件对小尾寒羊、大尾寒羊、豫西脂尾羊的羊毛物理特性进行了分析.结果表明:小尾寒羊、大尾寒羊、豫西脂尾羊的无髓毛质量比分别为(74.88±12.12)%、(85.05±13.93)%和(64.32±8.87)%,差异显著(P<0.05).3个绵羊品种的无髓毛根数比分别为(82.36±2.97)%、(89.184±8.18)%和(80.12±4.45)%,差异显著(P<0.05).此外,这3个绵羊品种的有髓毛质量比、有髓毛根数比、自然长度、无髓毛伸直长度、无髓毛细度也存在显著差异(P<0.05).分析表明,小尾寒羊的毛股较长,细度比其他2个品种较细;而大尾寒羊的无髓毛比例较高.
