Abstract: 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 than 0.05 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.

Key words: microelement selenium, feed additive, biological function, livestock and poultry, breeding
