【摘要】 对柴达山绒山羊母羊的绒层厚度、粗毛长度、产绒量、体重、体长、体高、胸围、管围、体侧部绒纤维伸直长度和绒纤维细度进行了表型相关的测算，结果表明：（１）对育成母羊产绒量影响较大的三个性状按决定系数大小依次为体长、绒层厚度和体侧部绒纤维伸直长度，呈现正向影响；绒层厚度还与体长和绒纤维细度协同产生对产绒量的正向影响；体重和体高对产绒量有较小的负向影响。（２）对成年母羊产绒量影响较大的性状按决定系数大小依次为绒层厚度、体重、粗毛长度、体高、胸围和绒纤维伸直长度，其中粗毛长度和体高呈现负向影响，其余性状为正向影响。更多还原

【Abstract】 The down thick, hair length, down production , they length , body,heights,chest girth,cannon circumference, extend down fiber length and fiber fineness of body side of female Chaidamu down-producing goat were tested with phenotype correlation. The results were as follows: (l) The three performances which effected the down roduction of improved female goats were body length,down thich and extend down fiber length of body side, arranged in determined coefficient from high to low, showed the positive influence; the weight and body height had a smaller negative influence on down production. (2) The performances which taken a bigger influence on down production of adult femal goats were down thick, weight, hair length ,body height, chest girth and extend down fiber of body side, arranged in determind coefficient from high to low, and the hair length and body height showed the negative influence while the other indexes showed the positive influence.更多还原
