Abstract The term amino-acid imbalance is used to characterise an experimental condition in which the rate of growth of an experimental animal is depressed by a supplement of an amino acid or acids other than the one s that is most limiting in the diet, with the proviso that none of the amino acids in the supplement is present in an amount that can be considered toxic.
