摘　　要：水产饲料常需添加氨基酸产品以满足水产动物的营养需求。蛋氨酸(Met)是水产动物的第一限制性氨基酸,参与机体多种代谢过程。蛋氨酸添加剂通常包括晶体蛋氨酸和蛋氨酸羟基类似物两类,并以DL-蛋氨酸(DL-Met)、L-蛋氨酸(L-Met)和蛋氨酸羟基类似物钙盐(MHA-Ca)较为常见。晶体蛋氨酸和蛋氨酸羟基类似物分别具有不同的理化性质,在动物体内有不同的吸收转化过程,二者的应用效果也存在较大争议。文章综述了晶体蛋氨酸和蛋氨酸羟基类似物的理化性质、生物代谢、应用和生产等现状,以期为蛋氨酸添加剂在水产饲料中的后续发展和应用提供参考。Amino acid products are often added to aquatic feed to meet the nutritional requirements of animals.Methionine is the first limiting amino acid of aquatic animals and participates in many a variety of metabolic process.Methionine additives contain crystal methionine and methionine hydroxy analogue,and DL-methionine(DL-Met),L-methionine(L-Met)and methionine hydroxy analogue calcium(MHACa)are more common.Crystalline methionine and methionine hydroxyl analogue have different physicochemical properties,respectively,and different absorption and transformation processes in animals,and the application effects of the two are also highly controversial.In this article,we provide a review of the physicochemical properties,biological metabolism,application and production status of crystalline methionine and methionine hydroxy analogue to serve as a reference for the subsequent development and application of methionine additives in aquatic feed.
