Selenium is a component of glutathione peroxidase, maintains the function of the cell membrane through oxidation, and increase the
production of protein lipid based endogenous antioxidants. It involves in the energy conversion, effects the metabolism, plays an
important role in the fat emulsification and absorption, and in the absorption of a variety of vitamins. At the same time, it
involves in the synthesis of coenzyme A and coenzyme Q, effects the function of other enzyme systems. It influences the metabolism
of amino acids, protein synthesis, carbohydrate metabolism, and biological oxidation. The lack of selenium in livestock and
poultry seriously affect the growth and reproduction.
