Stimulating antioxidant defences
Feed supplementation with selenium has been shown to improve the health status of animals by stimulating their antioxidant defences, through seleno-enzymes, such as gluthation peroxydase (GPx). This improves their immune and reproductive function while enhancing zootechnical performance and the quality of end products, such as meat and eggs. Supplementation with selenium from organic sources leads to better assimilation of selenium into animal proteins. Assimilated selenium can function as a reserve pool for animals during extreme stress.
Phileo by Lesaffre has developed a Selenium enriched yeast, from a proprietary yeast strain (CNCM I-3399), creating consistent end products which are 2/3 selenomethionine (SeMET) and 1/3 selenocysteine (SeCYS), plus other active selenium-components.
