摘  要：
为了研究被毛类型对白绒山羊重要经济性状的影响,试验通过对毛长测量值进行数据分析后分成9组,利用SAS9.0软件GLM以及Duncan’s多重比较方法,研究其对重要经济性状的影响。结果表明:白绒山羊的绒厚、产绒量、抓绒后体重、绒长、毛细、绒细等性状均随毛长的增加呈不同程度的增长趋势,且差异极显著(P<0.01)。毛长对绒细的影响不及对其他性状的影响显著;而毛长对产绒量的影响关系较为复杂,即被毛或长或短两个极端表现型的个体产绒量更大,且越趋于极端型,产绒量越高,处于两个极端表现型之间的个体产绒量最低。将内蒙古白绒山羊群体的被毛类型按其毛长测量值分为三个类型,即1~3分组(毛长≤13 cm)的白绒山羊为短毛型,4~6分组(13 cm<毛长≤22 cm)的白绒山羊为中间型,而7~9分组(毛长>22 cm)的白绒山羊为长毛型。

摘  要：
To study the effect of the types of hair coat on the other important economic traits of white cashmere goats,the data from hair length measurements were analyzed and divided into 9 groups. The GLM program and Duncan's multiple comparison method of SAS9. 0 statistical software were used to investigate the effects of hair length measurements on improtant economic traits of white cashmere goats. The results showed that the cashmere thickness,cashmere yield,body weight after combing,cashmere length,staple fineness and cashmere fineness and other traits presented different degrees of growth trend with the increase of hair length,and the differences were highly significantly( P < 0. 01). The effect of hair length on cashmere fineness was less significant than on other traits. However,the relationship for the effect of hair length on cashmere yield was more complex,namely,the individual cashmere goats with two extreme phenotypes of long or short hair coat had greater cashmere yield,and the more tending to the extremes,the higher cashmere yield. Individuals with the phenotype between the two extreme phenotypes had lowest cashmere yield. The types of hair coat in the population of Inner Mongolia white cashmere goats were divided into three types according to their hair length measurements,namely,short- haired white cashmere goats from 1 to 3 groups with hair length at 13 cm or less,medium- haired white cashmere goats from 4 to 6 groups with hair length between greater than 13 cm and less than or equal to 22 cm,and long- haired white cashmere goats from7 to 9 groups with hair length at greater than 22 cm.
