Abstract

Selenium (Se) is an essential element for animal nutrition that was discovered by the Swedish chemist Berzelius more than 200 years ago and its essentiality was confirmed in 1957. Since then, a great deal of information related to Se chemistry, biochemistry and molecular mechanisms of its action in human and animals has been accumulated. It is proven that Se deficiency is a worldwide problem and most feed ingredients used in poultry/animal nutrition contain low level of Se and therefore Se is included into premixes to meet Se requirement. Se assimilation in ruminants has some important features related to conversion of traditional form of Se supplement (sodium selenite) into non-available form (e.g., elemental Se) in the rumen. The data provided in previous 11 chapters of the book clearly showed a benefit of optimal Se status of animals on their health, productive and reproductive performance. Furthermore, organic Se in the form of SeMet can help overcome Se deficiency problems in dairy and beef industry and this is clearly summarised in this chapter. Pluses and minuses of various forms of Se in supplements are considered. New developments in Se action on animal health include effects of Se status on transcription factors in redox homeostasis maintenance. Possible molecular mechanisms of protective effects of Se on immunity under various stress conditions are considered. Indeed, anti-inflammatory properties of selenium deserve more attention in future research.
