| 摘 要： | 产毛量是毛兔主要的经济性状,利用体成熟前体重、体尺在不同生长发育阶段的净增量、累加量与年剪毛量的相关关系,进行回归分析,并建立最优回归方程对年产毛量进行早期估计。估计的准确度较高;复相关系数分别为:0.7850,0.6792,0.7699,0.7308。

| Abstract: | The wool yield is an important economy character of the Angora rabbit. The correlations of the net growth, the accumulated weight and the wool yield per year of the body weight and the body size, have been used for regression analysis and a best regression equa tion has been iounded. According to the equation, yearly wool output can be estimated in early stage. Its Accuracy is high. The multiple correlation coefficients are separately. 0. 7850, 0.6792, 0. 7699 and 0. 7308. |
