Statutory restraint on use of organic selenium
A European study has looked at selenium limits in animal products. From this study, the EFSA has concluded that levels of more than 0.2 mg organic selenium per kg compound feed lead to higher levels of selenium in animal products, which could exceed the safety boundary of selenium intake for certain consumers.
The EU has therefore imposed a maximum of 0.2 mg organic selenium per kg of complete feed. The composition of a number of premixes and mineral mixes will be adjusted in compliance with the new statutory maximum level.
Selenium is an important trace element in animal feeds. Selenium acts as an antioxidant in the body and plays an important role in improving the immune system, the regulation of thyroid hormone metabolism and fertility and reproduction. That is why selenium forms an important part of premixes for cattle, pig and poultry feed. Selenium is also an important trace element in mineral feed. In practice, selenium can be added to premixes and mineral feed in two forms: in inorganic form and in organic form, which involves selenised yeast in which sulphur in sulphur-containing amino acids is replaced by selenium. Selenium from selenised yeast is better absorbed by the body than selenium in inorganic form.
