L-Threonine feed grade
L-Threonine is an indispensable essential amino acid for animal growth and one of the limiting amino acids in livestock and poultry feed. It cannot be synthesized independently by animal organisms and must be supplemented through daily feed. As a high-efficiency and eco-friendly feed additive, feed-grade L-threonine is produced by advanced microbial fermentation technology, featuring high purity, stable quality and excellent biological activity. It is widely used in the feed formula of swine, poultry, ruminants and aquatic animals.
