摘  要:
硒是一种人体和动物机体生长发育必不可少的微量营养素,在动物的吸收代谢、生长发育、繁殖、免疫以及临床保健等方面起关键作用.在家畜和家禽饲料中添加一定剂量的硒对其健康具有重要意义.据报道,中国有约3/4的地域属于低硒区或缺硒区,超过3/5的地域所生产的饲料原料中含硒量<0.05 mg/kg,根本无法满足畜禽的生长发育需求.由此可见,微量元素硒作为一种饲料添加剂在畜禽养殖上应用也越来越广泛.综述了微量元素硒的生物学功能,硒补充剂的分类以及硒作为饲料添加剂在不同种动物生产上的应用等方面.

摘  要:
Selenium is an essential microelement for human and animal growth and development, which plays a key role in animal metabolism, growth, reproduction, immunity and clinical health care.Adding a certain dose of selenium to livestock and poultry feed is important for their health.It is reported that about three-fourths of the regions in China belong to low selenium areas or selenium deficiency areas. Selenium content in feed feedstock produced in more than 3/5 regions is less than0.05 mg/kg, so that the growth and development requirements of the livestock and poultry cannot be met. Therefore, as a kind of feed additive, trace element selenium has been widely used in livestock and poultry production. The biological functions of trace element selenium, the classification of selenium supplements and the application of selenium as a feed additive in the production of different species of animals were reviewed.
