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, in addition dietary supply through feed materials is usually insufficient.
The deficiency of L-Tryptophan was generally chatacterized as decreased feed intake and efficiency , and feed 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 balance and fulfill the digestible trytophan requirement of animals, especially piglets , ows and poultry etc.
