摘要
硒是动物和植物必需的一种微量元素,近年来随着科技的进步和生产力的提高,硒的研究已成为热点,特别在反刍动物添加方面,硒对于养殖行业以及疾病治疗(白肌病等)方面都有至关重要的意义。文章从硒的形态及分布出发,具体阐述硒和动物之间的关系,包括不同剂量的硒对动物的影响、硒在动物体内的分布和硒元素在动物体内的具体消化代谢过程等;介绍硒对动物生理生化方面的作用,包括抗氧化功能、促免疫功能、促进生长以及促进繁殖等功能,概括硒的分布、研究现状以及研究方向;总结了硒在动物中最适合的添加量,最后展望未来硒的研究方向和一些未知领域。
Selenium is a trace element which is necessary for animals and plants. In recent years, with the development of productivity and technology, more and more science researches focus on selenium, especially in the ruminant addition experiments, selenium is of vital importance for the breeding industry and disease treatment(white myopathy etc.). Starting with the form and distribution of selenium, this paper expounded the relationship between selenium and animals, including the effects of different doses of selenium on animals, the distribution of selenium in animals, the specific digestive and metabolic processes of selenium in animals, etc. The effects of selenium on animal physiology and biochemistry were summarized, including the functions of antioxidant, immune promotion, growth promotion and reproduction promotion. Then the distribution, research status and research direction of selenium were summarized. The most suitable amount of selenium in animals was determined. Finally, the future research direction and some unknown areas of selenium were prospected.
