Use of aqueous L-tryptophan and/or L-threonine salt solutions

摘要

Storage-stable, highly concentrated aqueous solutions of L-tryptophan and/or L-threonine salts containing 30-70 wt. % of L-tryptophan and/or L-threonine are used to supplement animal fodder and industrially prepared mixed fodder with L-tryptophan and/or L-threonine. Preferably supplementation is with 0.01-5.0 wt. % of soluble L-tryptophan and/or L-threonine salt, especially the sodium and/or potassium salt.
