摘　　要：微量元素对畜禽生长、发育和繁殖等生命活动至关重要,畜禽缺乏微量元素会导致生长迟缓、免疫缺陷及繁殖障碍等,严重影响养殖效益。目前,微量元素常以过量的无机盐形式添加至饲料中,以满足动物需要,但这大大增加了粪污微量元素排放,污染生态环境。近年研究发现,有机微量元素的吸收利用率高于无机微量元素,可以减少畜禽微量元素排放,但相关机制尚不完全清晰。本文基于现有研究成果,阐述了无机和有机形式的铁、铜、锰、锌的吸收途径,以期为畜禽有机微量元素制剂开发应用提供理论参考。Trace elements are essential for the growth,development and reproduction of livestock and poultry.Lack of trace elements can lead to growth retardation,immunodeficiency and reproductive disorders,which seriously affect the efficiency of animal breeding.Currently,trace elements are often supplemented to feed in the form of excessive inorganic salts to meet the needs of animals,but this greatly increases the discharge of trace elements in feces and pollutes the ecological environment.Recent studies have found that the absorption and utilization rates of organic trace elements are higher than those of inorganic trace elements,which can reduce the emission of trace elements in livestock and poultry,but the relevant mechanism is still not very clear.In this paper,the absorption pathways of organic and organic forms of iron,copper,manganese,and zinc are elucidated based on the results of existing studies to provide a theoretical reference for the development and application of trace element preparations in livestock and poultry breeding.
