selenium-rich feed, the selenium in the animals can be accumulated; if pigs, cattle, sheep, birds and the like are raised by using the selenium-rich feed, the meat, eggs, milk and the like, which are produced by the pigs, the cattle, the sheep, the birds and the like, contain the selenium easily absorbed by a
human body and can be taken as selenium-rich products for human consumption. The organic selenium-containing cattle and sheep feed has the advantages of being economical, convenient and efficient. The selenium-rich
feed additive produced by the method is determined to contain 6000-10000mg / kg of selenium. The cattle and sheep feed provided by the invention has the advantages of being rich in selenium and containing rich
