Application
Similiar to Lysine, L-Threonine is important amino acid in the process of protein synthesis of livestock. If Lysine is usually added into poultry feed, however, L-Threonine is needed in swine dietary supply. Swine farm add L-Threonine in feeds to boost nutrition and therefore quality of the swine. L-Threonine not only increase biological value of the feed protein, but it also decreases nitrogen excretion and reduces environmental pollution.
