蛋白质饲料是水产饲料中最贵的成分。动物对蛋白质的需要实质是对平衡的必需氨基酸的需要,因此,从这一角度讲,优化水产动物的氨基酸营养可以节约蛋白,从而降低饲料成本,最大限度地提高产品利润率。氨基酸是构成鱼体蛋白以及功能性蛋白的基本营养素,任何一种必需氨基酸的缺乏都会导致生长减缓和饲料转化降低,氨基酸营养方面的研究工 Protein feed is the most expensive ingredient in aquafeed. The animal’s need for protein is essentially the need for a balanced list of essential amino acids, so from this perspective, optimizing aquafeed’s amino acid nutrition saves protein, reducing feed costs and maximizing product profitability. Amino acids are essential nutrients that make up fish proteins and functional proteins. The lack of any essential amino acid leads to reduced growth and reduced feed conversion.
