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 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. The Adaptability includes:
--Improve the feed quality and animal growth.
--As feed additive, it is widely used in pig feed to add all kinds of pig feed, chicken feed, and shrimp feed, eel feed etc.
--It is the second limiting amino acid for pigs after Lysine and improves zootechnical performance.
--It reduces nitrogen waste in the excrement and urine of animals so that the release of ammonia is slowed and the ammonia concentration is kept low in animal shed.
--General if is used in conjunction with the lysine to further improve the quality of feed.
The recommended dosage in formula feed or complete feed (calculated according to L-Trytophan:
