Product Description L-Threonine is an essential amino acid that is added to the diet of pigs and poultry in order to exactly match the balanced amino acid requirement of the animals. In practice, L-Threonine is the second limiting amino acid for pigs and the third for poultry. Even in the low protein diets with such balanced L-Threonine content, L-Threonine can optimize growth performance and decrease the excretion of nitrogen. It is cost-effective and environment friendly.

It is important for the formation of collagen, elastin, and tooth enamel, and aids liver and lipotropic function when combined with aspartic acid and methionine. Application Improvement of animal performance through better amino acid balance Sparing consumption of the crude protein content Improvement of carcass quality Prevention of Threonine deficiency
