饲料蛋白质的主要目的是提供氨基酸以合成机体蛋白。最有利的蛋白质合成是:同时向机体组织提供比例适宜的各种必需氨基酸。当摄食量过高且其需要量可能不同程度地依赖于所摄食蛋白质中其他必需氨基酸的平衡时,某些氨基酸甚至是有毒的。业已研究了几种鱼类包括鲤鱼对必需氨基酸的定量需要。但许多研究未进一步阐明氨基酸平衡对鱼类饲料蛋白质利用率的影响。本试验研究了鲤鱼鱼种摄食不同氨基酸组成的饲料时饲料氨基酸平衡 The main purpose of feed proteins is to provide amino acids to synthesize body proteins. The most favorable protein synthesis is: At the same time to the body tissue to provide a suitable proportion of the various essential amino acids. Some amino acids are even toxic when the food intake is too high and its requirements may depend, to varying degrees, on the balance of other essential amino acids in the protein being ingested. Several species of fish including carp have been studied for the quantitative needs of essential amino acids. However, many studies did not further elucidate the impact of amino acid balance on the efficiency of fish feed protein utilization. In this study, carp fingerlings fed diets containing different amino acids were fed on amino acid balance
