Fermentation-derived essential amino acid — the most cost-effective lysine source for commercial swine and poultry feed.
Product Overview
Our L-Lysine Sulphate (65%) is a granular feed-grade amino acid produced by submerged fermentation of our own corn dextrose using a proprietary Corynebacterium glutamicum strain. The whole fermentation broth is spray-dried without purification — giving a cost-optimised product that also delivers residual B-vitamins and yeast metabolites.
Lysine is the first limiting amino acid in most corn-soy diets for swine and poultry. Supplementing with L-Lysine Sulphate allows feed formulators to reduce crude protein levels, lower nitrogen excretion, and improve feed conversion — while cutting cost per tonne of finished feed.
Our Shouguang lysine plant is one of the largest dedicated amino-acid fermentation complexes in Asia, with a nameplate capacity of 450,000 tonnes per year across sulphate and HCL grades.
Key Features
No dust issues in premix blending; uniform distribution.
Fermentation broth retains natural thiamine, riboflavin, and biotin.
Retains ≥98% activity through 85 °C steam conditioning.
Equivalent bioefficacy to HCL grade on an equi-lysine basis.
Lowest cost per unit of digestible lysine delivered.
450,000 t/yr capacity — zero supply-chain anxiety.
