通过氨基酸分析，计算了银鲑、虹鳟、鱼苗和饲料的A/E比值，并以银鲑鱼苗的必需氨基酸模式作为参考模式。以酪蛋白为唯一蛋白质源的日粮，通过补充氨基酸，使其必需氨基酸模式与参照模式相似。在为期6周的饲养试验中，采用3种不同蛋白质水平的饲料和鱼粉饲料作为对照，研究了氨基酸对生长的补充作用。最差的增长，观察到在鱼喂酪蛋白饮食（40%的蛋白质），没有氨基酸补充。与鱼粉饲料相比，补充氨基酸饲料的组获得了更好的生长和饲料效率。在这些处理中，用低蛋白质饮食（33%蛋白质）喂养的鱼显示出与40%蛋白质酪蛋白饮食相同的生长速率。
After amino acid analyses, A/E ratios of coho salmon, Oncorhynchus kisutch, fry and the feedstuffs used were computed, and the essential amino acid pattern of coho salmon fry was used as a reference pattern. The essential amino acid pattern of the diets composed of casein as a sole protein source was simulated to those of the reference pattern by supplementing amino acids. The supplemental effect of amino acids on the growth was examined in a six-week feeding trial using diets with three different protein levels and fish meal diet as a control. The poorest growth was observed in the fish fed casein diet (40% protein) without amino acid supplementation. Much better growth and feed effciency were obtained in groups fed with the diets of amino acids supplementation comparable to those of the fish meal diet. Among these treatments, the fish fed with the low protein diet (33% protein) showed the same growth rate as a 40% protein casein diet.
