In the daily feeding process of animals, the demand for the trace element "selenium" in the feed is essential. Selenium participates in a series of physiological and biochemical processes in the animal body, although the demand is small.
Selenium has many biochemical functions, the most important of which is its antioxidant activity, which mainly works through selenium enzymes. Selenium is closely related to the functions of vitamin E, both of which protect biofilms from oxidative damage.

There are two selenium products that can be used in feed, yeast selenium and sodium selenite. Among them, the maximum limit of selenium in the feed is 0.5ppm, and the recommended addition amount is 0.1~0.3ppm
