摘  要:
对北疆1—6岁共60头天山马鹿的体重(x1),体长(x2),胸围(x3)和管围(x4)与产茸量(y)采用相关分析及多元回归分析,建立了产茸量的估测模型^y=1070.24+22.82x1-32.89x3,经检验此模型的适合度、回归系数和复相关系数均差异极显著(P<0.01)。模型预测效果良好,为天山马鹿的选育提供了科学的参考依据。

摘  要:
The experiment was design to analyze multiple regression of body weight and body length and circumference of cannon bone with quantity of pilose antler of a young stag of 60 red deer about 1 to 6 years old. Testing the estimation model (= 1070.24 +22.82x_1 -32.89x_3), the result indicate that fitness and regression coefficient and multiple correlation coefficient were significantly difference respectively (P<0.01). The estimation model can estimate more accuracy, which would be very useful in Tianshan red deer breeding.
