摘要
A new chemical index-imbalance degree (IBD), was proposed on the basis of cluster analysis in multivariate statistical analysis to estimate the extent of amino acid balance in protein. The range of IBD is between 0 and 1, successively corresponding to complete balance and entire imbalance for the amino acid profile of a sample. The amino acid increment model of IBD belongs to an asymmetrical maximum-type, and there is a high correlation between IBD and coefficient of variation (CV). The nutritional value of individual feed can be ranked and clustered according to its IBD; and by calculating the IBD of amixed sample with two or more feedstuffs, it is Possible theoretically to predict whether a synergetic. pheno men on exists and when an optimal mutual complement can happen. If the conceptive frame of IBD extended, it can be used to study the balance of nutrients besides amino acids, and is helpful to realize the automatic distinction and selection in diet formulating.
