| 摘 要： | 对94只母貂的体重(x1),体长(x2),管围(x3)与其产仔数(y)采用相关分析及多元回归分析,建立了产仔数的估测模型^y=1.666-0.005x1+0.332x2,经检验此模型的适合度,回归系数和复相关系数均差异显著(P<0.05)。模型预测效果良好,为准备配种期母貂的体况调整提供了科学的参考依据。

| Abstract: | The experiment was designed to analyze multiple regression of body weight and body length and cannon circumference with litter size in 94 female minks. Testing the estimation model( =1.666-0.005 x1+0.332 x2), the results indicate that fitness and regression coefficient and multiple correlation coefficient were different respectively （P<0.05）.The estimation model worked effectively, which provided a scientific reference for the female mink which prepares for mating to adujust its body condition. |
