Betaine anhydrous as a feed additive for all animal species based on a dossier submitted by Trouw BV

Glycine betaine (betaine) acts as a methyl group donor in transmethylation reactions in organisms. Betaine occurs in numerous vertebrate tissues as an osmolyte, ensuring osmoprotection. Betaine is safe for piglets at the maximum supplementation rate of 2 000 mg/kg complete feed with a margin of safety below 5. This conclusion is extended to all pigs and extrapolated to all animal species and categories.
