Selenised yeast Saccharomyces cerevisiae CNCM I-3060, inactivated Preparation of organic selenium: Content of selenium: 3 000 to 3 500 mg Se/kg (3b810i)

What it is. Selenised yeast obtained from Saccharomyces cerevisiae strain CNCM I-3060, inactivated after fermentation on a selenium-enriched substrate. The additive contains 3,000 to 3,500 mg Se/kg, of which more than 97 to 99% is organic selenium and more than 63% selenomethionine.

What it is for. This additive supplies organic selenium, used as a trace element source in complete feed for all animal species. It is incorporated into feed via premixtures and is intended to cover selenium requirements with an organic form considered to have different bioavailability from inorganic selenium sources. It is generally used in feed formulation when an organic selenium source is preferred over sodium selenite or selenate.

Points to watch. Total selenium supplementation from this additive must not exceed 0.2 mg Se/kg complete feed at 12% moisture, and total selenium content (all sources) in complete feed is capped at 0.50 mg/kg. The dust potential of the additive must ensure maximum selenium exposure of 0.2 mg Se/m3, requiring operational procedures and, where needed, respiratory protective equipment. Storage and stability conditions are specified in the additive and premixture instructions for use.
