摘要:

Diets were computed to contain equal concentrations of digestible crude protein either of wheat gluten (diet 1) or of grieves (diets 2–8). Per kg dry diet, 41 g crystalline amino acids were supplemented. All diets contained at least 1.2 g Lys per MJ digestible energy (DE). In diet 2, ratios of Met + Cys, Trp, Leu, Ile and Phe to Lys were about equal to those in diet 1. In each of diets 3–7, one of the respective amino acids, in diet 8 all five were replaced by Glu in the supplemented mixture of amino acids.
