Animal feeding stuffs. Determination of lysine, methionine and threonine in commercial amino acid products and premixtures Ingestion-build-143074 namely Method A and Method1 Scope This International Standard specifies a method for the quantitative determination of free (non protein bound) lysine, methionine, and threonine in commercial products and premixtures containing more than about 10 % mass fraction of the respective amino acid. It does not distinguish between d and l forms. NOTE For the purposes of this International Standard, the term amino acids used in Clause 2 onwards refers to lysine, methionine, and
