Biological and physiological role and using of selenium compounds in livestock and poultry

Abstract

The role of selenium as a trace element and antioxidant and the ability of selenium nanoparticles to exhibit enzyme-like activity are considered. Its bioavailability, ways of assimilation and elimination are covered. Emphasis is placed on a much more pronounced positive effect on the metabolism of animals and poultry of probiotics enriched with organic, inorganic and nano-forms of selenium.
