L-Tryptophan is one of essential amino acids and the fourth limiting amino acid in animal diets,  which means it could not be synthesized by the body,the deficiency of L-Tryptophan was generally characterized as decreased feed intake and  efficiency, and slow growth rate. Considering L-Tryptophan playing a key role in growth performance and  feed efficiency, it is recommended to add L-Tryptophan in diet to achieve the optimal amino acid balance  and fulfill the digestible tryptophan requirement of animals, especially piglets, sows and poultry etc

L-Tryptophan can improve animal food ingestion, weaken stress reaction, improve animal sleeping, increase antibody of fetus and young animal and improve milk secretion of milk yielding animals; it’s also can be used to reduce high quality protein dosage in daily ration, reduce feed cost, protein feed consumption of daily ration and save formula space.
