Selenium can be added to livestock diets in either inorganic forms (sodium selenite, SS), organic forms such as Se-yeast (yeast enriched in SeMet), or pure chemically synthesized Se forms such as hydroxyselenomethionine (HMSeBA), L-SeMet or ZnL-SeMet. Recent advances in Se biochemistry have provided a deeper understanding of the principal differences in absorption and metabolism between these forms.

 
There is now much evidence that the SeMet proportions of Se are the main drivers of efficacy in organic form. Selenium, via selenoprotein expression, is involved in the protection against oxidative stress and the regulation of various cell functions. Therefore, increased muscle reserves of Se can enhance livestock resistance to stress and diseases.
