Detailed Photos

1. Improve performance: Tryptophan is one of the essential amino acids for protein synthesis, which can promote the development of muscle tissue and improve the performance of animals. Studies have shown that the addition of tryptophan to feed can significantly increase the growth rate and feed conversion rate of animals, and reduce the cost of feed.
2. Enhance disease resistance: tryptophan can be converted into serotonin in animals, and serotonin is an important immunomodulatory factor that can enhance the immunity of animals. At the same time, tryptophan can also promote intestinal peristalsis, maintain intestinal patency, and reduce the risk of disease.
3. Regulation of the nervous and endocrine system: tryptophan is a precursor to the synthesis of 5-hydroxytryptamine and tryptamine. These two substances have important regulatory effects on the nervous and endocrine system of animals, which can improve the mood and stress state of animals, reduce production pressure, and promote growth and development
