摘要
阿尔巴斯白绒山羊有关性状的相关分析表明,成年母羊的绒厚与产绒量、毛长与产毛量之间有极显著的正相关关系(P<0.01),体长与产绒量之间有显著的正相关关系(P<0.05),绒细与毛长之间有极显著的负相关关系(P<0.01),绒细与产毛量、产绒量与产毛量之间有显著的负相关关系(P<0.05)。育成母羊的体长与产毛量、胸深与产绒量、绒厚与产绒量、毛长与产毛量之间有极显著的正相关关系(P<0.01),胸深与产毛量、绒厚与毛长、绒毛与产绒量、绒长与产毛量之间有显著的正相关关系(P<0.05)。从产绒量与其它性状间的多元回归结果来看.成年母羊与育成母羊的产绒量与绒厚之间都有极显著的正相关关系(P<0.01),成年母羊的产绒量与毛长之间有极显著的负相关关系(P<0.01)。
In this paper, the relationships between characters which related to the cashmere productivity of the arbes white Cashmere goat are studied by correlation and multiple regression analtsis. The results show that in adult doe, there are strong posytive correlations between cashnere yield and thickness, hairlength and yield (p<0.01); There is strong negative correlation between cashmere fineness and length (p<0.01); The correlation between body length and cashmere yield is positively significant (p<0.05), while the correlations between casshmere fineness and yield, hair and cashmere yield are negatively significant (p<0.05), In growing doe, there are strong positive correlations betwneen body length and hairyield, chest depth and cashmere yield, cashmere thickness and yieldd, hair length and yield (p<0.01) However, the correlations between chest depth and hair yield, cashmere thickness and hair length, cashmere length and yield, cashmere length and hair yield are positively significant (p<0.05) The multiple regression analysis also indicated that there are strong positive correlations between cashmere yield and thickness (p<0.01) in both adult and growing doe, but the correlation between cashmere and hair length is highly ne-gative (p<0.01) in adult doe.
