Description
What it is. L-threonine (3c412) is an essential amino acid obtained by fermentation using Escherichia coli CGMCC 7.455. The additive is a powder containing a minimum of 98.5% L-threonine, with a maximum moisture content of 1%.
What it is for. This amino acid is used to balance dietary threonine, often a limiting factor after lysine and methionine, in formulas for all animal species. It allows reduction of crude protein levels in feed while meeting requirements, following the ideal protein concept. The additive can be incorporated into premixes, compound feed, or directly into drinking water.
Points to watch. The instructions for use must specify storage conditions as well as stability to heat treatment and in water. No maximum use level is set in the regulatory annex; dosage depends on formulation according to species needs and physiological stage.
