L-TRYPTOPHAN 98.5% (FEED GRADE)

L-Tryptophan can participate in the renewal of plasma proteins in animals, promote the role of riboflavin, contribute to the synthesis of nicotinic acid and heme, significantly increase the antibodies in fetuses of pregnant animals, and promote the lactation of dairy cows and sows during lactation. When livestock and poultry lack tryptophan, growth stagnates, body weight decreases, fat accumulation decreases, and testicles of breeding males shrink. It is used in medicine as a preventive and therapeutic agent for leprosy. 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.
