动态饲养指标的统计比较方法探讨

不同饲养管理条件下动态指标的统计比较方法，应视饲养试验目的而定，当研究者只注重最终饲养效果时，可灵活地选用方差或协方差分析法，若以揭示饲养管理条件作用机理为目的，重视动态指标变化规律时，应首先采用数学模型方法，将个体动态指标的变化规律用为数不多的模型参数描述，饲养管理条件作用间这些参数之差异便反映了动态指标变化规律之差异，考虑到每个参数的估计误差，为提高统计检验的准确度，还有必要引入广义方差分析法

Discussion About Statistical Comparison Methods of Dynamic Feeding Index

The methods of comparing feeding conditions depend on the aims of the feeding experiments, Variance or covariance analysis is useful when the end is to compare the final feeding results, Sometimes the research is to get the mechanism about the function of the feeding conditions and paying attention to the variation of the dynamic index, The variation in mathematical model getting some parameters is stated. The difference of paramaters among feeding conditions Just reflects the different forms of variations in dynamic indexes. Considering the estimated errors from each parameter, to increase the accuracy of statistical test,the generalized variance analysis is used in this paper.
