Product Description

Product tryptophan

DIRECT SUPPLY FEED ADDITIVE L TRYPTOPHA
L-Tryptophan is one of essential amino acids and the fourth limiting amino acid in animal diets, which means L-Tryptophan could not be synthesized by the body. In addition, dietary supply through feed materials is usually insufficient.

Tryptophan is used to supplement feeds in order to meet the digestible tryptophan requirement of animals. It is particularly suitable for young pigs, because it helps to improve feed intake, growth rate and feed efficiency.The deficiency of L-Tryptophan was generally characterized as decreased feed intake and efficiency, and slow growth rate.

Application

1. Nutritional supplements. Tryptophan contained in egg white protein, fish, corn flour, etc. is a limiting amino acid, and the content in grains such as rice is relatively small. It can be combined with lysine, methionine and threonine to strengthen amino acids. 2. L-Tryptophan can improve nutrition and enhance physical fitness, and can be used for nutritional and biochemical research and preparation of tissue culture medium.
