摘要
使用Logistic模型配合家畜生长曲线时,应以家畜成年体重为模型中的最大生长量估计值,其他参数以实测值直接估计。采用四个实例比较了这种配合模型的方法与经典教科书上介绍的方法,表明这种新方法较优。
When Logistic model was proposed to fit livestock growth curve, livestock aduh body weight should be the estimation of maximum growth, other parameters should be actual measurement data. Four examples were adopted to compare the model method and simplifying one which introduced by classical books. The result indicted that the new method was better than the old one in most cases.
