| Summary |
Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in humans, farm animals and poultry through its incorporation into a range of selenoproteins. Low Se content in main feed ingredients is a common problem worldwide and dietary Se supplementation is a current practise in poultry and farm animal nutrition. Recent research clearly proved that sodium selenite, used for the last 40 years as a feed supplement, is not an optimal form of Se. However, use of organic selenium in animal/poultry diets can help meeting Se requirement and m. |
