L-Threonine is an indispensable amino acid as well as the third limiting amino acid in most poultry and swine diets [beyond Lysine and Methionine]. The commercial introduction and use of crystalline feed grade L-Threonine has provided nutritionists with a tool that allows them to economically balance dietary protein and meet the amino acid requirements of today’s high-yielding livestock.

Since the commercialization of crystalline L-Threonine, Ajinomoto Heartland, Inc. has improved the quality of L-Threonine through granulation. Granulated L-Threonine offers superior flowability, less dust, and a particle size distribution that results in better mixability – three key value-added properties that are desired when supplementing an essential nutrient at the feed mill.
