对虾微量元素研究进展

Effects and research progress of trace mineral nutrition in shrimp

微量元素作为多种酶的辅助因子或结构成分,参与机体多种新陈代谢过程,在维持动物健康和正常生理功能中发挥着极其重要的作用。动物对微量元素营养需求极少,但缺乏、过量或摄入不平衡都会对动物机体生长代谢、免疫、繁殖等带来严重不良影响。本文较详细、系统地总结了国内外关于微量元素在对虾生长代谢、免疫、疾病预防、性腺发育等方面的作用,以及对虾对无机和有机微量元素的吸收、转运和代谢机理,为今后开展对虾优质配合饲料研发提供理论依据。

Trace elements, as cofactors or structural components of various enzymes, participate in various metabolic processes and play a key role in maintaining animal health and normal physiological function. Although trace elements requirements for animals are very small, lack, excess or imbalance of intake will bring serious adverse effects on animal growth, metabolism, immunity and reproduction. In this review, the effects of trace elements on growth and metabolism, immunity, disease prevention, gonadal development and other aspects of shrimp, and the mechanism of absorption, transport and metabolism of inorganic and organic trace elements were systematically summarized, which might provide theoretical basis for the development of shrimp feed in the future.
