Abstract: Selenium is an important trace mineral element, which plays an important role in animal physiological activities. Selenium-enriched probiotics can convert inorganic selenium into organic forms, promoting the absorption and utilization of selenium and in turn enhancing the antioxidant capacity and immunity of dairy animals, and can also increase the content of selenium in dairy products, thereby improving the nutritional value and quality of dairy products. In order to provide a reference for the development of dairy production in the future, this paper reviews the application of selenium-enriched probiotics in dairy production, discusses the effects of selenium-enriched probiotics on the production performance, milk yield and quality of dairy animals, and analyzes future development of selenium-enriched probiotics.

Key words: selenium-enriched; probiotics; dairy industry; dairy animals
