摘　　要：硒(Se)是动物机体必需的微量元素,在机体抗氧化体系、免疫细胞功能、促生长及精子的形成和游动、前列腺素的功能等方面起着重要作用。动物体内已知存在35种以上的含硒蛋白质,其中谷胱甘肽过氧化物酶(GPx1-GPx6)和硫氧还蛋白还原酶(TrxR1-TrxR3)在机体抗氧化体系中发挥着重要的作用。国内生产中通常应用亚硒酸钠作为补硒制剂,但亚硒酸钠在使用中存在吸收率低、过氧化作用及潜在的污染等问题。有机硒和纳米硒具有吸收率高、生物活性强、环境污染小等优点。与有机硒相比,纳米硒有更显著的低毒高效性,是已发现的毒性最低的补硒制剂。近年来,纳米硒替代有机硒、无机硒源的研究已成为热点。Selenium（Se） is an essential trace element of fundamental importance to antioxidant system,immune cell function,growth-promoting,sperm formation and swimming,function of prostaglandin.It present within at least 35 selenoproteins.Glutathione peroxidases（GPx1-GPx6） and thioredoxin reductases（TrxR1-TrxR3） play important role due to its antioxidant.Sodium selenite is used as the commercial Se source supplement in animal feeds in the China,but sodium selenite exists many problems such as lower absorption rate,peroxidation and potential contamination.Organic selenium and nano-selenium have many advantages such as increase absorption rates,biological activity,and reduce environmental pollution.Nano-selenium compared with the organic selenium have more significant efficiency and lower toxicity.nano-selenium is the lowest toxicity of Se source already founded.In recent years,the research of Nano-Se substitute for organic selenium and inorganic selenium sources has become a hot spot.
