羟基蛋氨酸金属螯合物作为一类新型的有机微量元素饲料添加剂,既可提供动物生长所必需的无机微量元素,又可提供蛋氨酸营养源,成为饲料添加剂的新宠,蓬勃发展起来。文章从羟基蛋氨酸、无机微量元素、羟基蛋氨酸金属螯合物、羟基蛋氨酸及其金属螯合物作为饲料添加剂的生物化学机理等角度阐述了羟基蛋氨酸及其金属螯合物在饲料添加剂中的应用进展,并对该领域的未来发展趋势进行了展望。 As a new type of organic trace element feed additive, hydroxy methionine metal chelate can not only provide inorganic trace elements necessary for animal growth, but also provide methionine nutrition source, become the new favorite of feed additive and flourish. The progress of application of hydroxymethine and its metal chelates in feed additives was introduced from the aspects of biochemical mechanism of hydroxy methionine, inorganic trace elements, hydroxymethion metal chelate, hydroxymethionine and their metal chelates as feed additives , And looks forward to the future development trend in this field.
