L-Threonine (Feed Grade)

Product Description

L-threonine is one of the essential amino acids. Not only is it necessary for the protein synthesis, also it plays an important role in protecting the intestinal barrier function. It is the second restrictive amino acid for pig diet, and the third restrictive amino acids for poultry diet. As lysine products are widely used in compound feed, threonine has gradually become the main amino acid affecting the livestock and poultry production performance. After adding lysine into the low protein diet, threonine became the first restrictive amino acid for growing pig. With the development and improvement of livestock's health breeding technology, threonine is increasingly widely used in the feed of poultry, shrimp and eel.
