In the past, swine and poultry diets were formulated using a specified crude protein level that was proven to provide an acceptable level of production. However, widespread commercial production of supplemental amino acids and further refining of swine and poultry amino acid requirements have provided nutritionists with the option of reducing dietary crude protein without compromising performance levels.

L-Lysine Sulphate 70% is primary restrictive amino acid; the main job for L-Lysine Sulphate is to participate in the compounding and precipitation of protein. It can also boost the absorption and utilization of the metallic elements.  As an environment friendly feed additive, L-Lysine can ensure the growth of the animal and reduce the protein level and cost in the diary ration at the same time.
