饲料中添加赖氨酸对鱼类生长的影响

Effect of dietary Supplementation with Lysine on the growth of fish

赖氨酸在机体代谢过程中有着重要的作用,是鱼类所必需而植物蛋白中含量不足的限制性氨基酸。通过植物饲料中添加赖氨酸不仅可以代替高成本的鱼粉,而且因为植物蛋白中磷的含量比鱼粉少,还可以降低对环境中磷的排放量,减少环境污染。

Lysine as the ＂life amino acid＂ plays an important role in the metabolism in organisms and is restrictive amino acid necessary for fish but less in plant protein content. Adding lysine to plants feed can not only replace the fish meal of high cost, but also reduce the emissions of phosphorus to the environment, and less environmental pollution, for the content of phosphorus of plant protein is less than fish meal.
