【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(P0.01)。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。
[Abstract]:In order to study the effect of coat type on important economic characters of white cashmere goat, the experiment was divided into 9 groups by analyzing the data of wool length measurement, and using SAS9.0 software GLM and Duncan's multiple comparison method. To study its influence on important economic characters. The results showed that the cashmere thickness, cashmere yield, weight after cashmere grabbing, velvet length, capillary size and velvet fineness of white cashmere goats increased with the increase of wool length, and the difference was very significant (P0.01). The effect of wool length on velvet fineness was less significant than that on other traits. The effect of wool length on the yield of wool is more complicated, that is, the individual with two extreme phenotypes of wool or length or short is larger, and the more extreme type, the higher the yield of wool, and the lowest amount of individual cashmere is in the middle of the two extreme phenotypes. The coat types of Inner Mongolia white cashmere goats were divided into three types according to the measured value of wool length. The white cashmere goats divided into 1 and 3 groups (wool length 鈮，
