蛋氨酸是重要的含硫必需氨基酸,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,特别是饲料原料中豆类的第一限制性氨基酸。通过植物饲料中添加蛋氨酸,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。 Methionine is an important sulfur-containing essential amino acid, and plays an important role in the body’s metabolism. It is a limited amino acid which is necessary for fish and contains insufficient contents in plant proteins, especially the first limiting amino acid in legumes in feed ingredients. Adding methionine to plant diets not only replaces high-cost fishmeal, but also reduces the amount of phosphorus in the environment and reduces environmental pollution because it contains less phosphorus than fishmeal.
