L-Lysine HCl (Amino-L) is one of the most widely used amino acid. It is an essential amino acid required in the diets of swine, poultry and most other animal species. L-lysine HCl is frequently the first-limiting amino acid in many of the additives commonly included in swine and poultry is not inly justified on the basis of least -cost formulation ,but also enables the nutritionist to balanse the diet to meet the animals requirement most closely,improving the meat quality and pramoting the growth of animals,it is widely used in feed additive industry.
L-THREONINE is the necessary complement of L-Lysine for which it optimizes the use by animals for body protein deposition and weight gain.Morever,L-Threonine plays an important role in processes of maintenance and,more Particularly of digestion.In Practice,L-Threonine is the second limiting amino acid in feed for pigs and the third limiting amino acid in feed for poultry L-Threonine ia a high quality product specification designed for the feed industry.
L-TRYPTOPHAN is one of essential amino acids and the fourth limitimg amino acid in animal diets,which means it could not be synthesized by the body,in addition,dietary supply through feed through feed materials is usually insufficient.
