L‑Lysine Sulphate 70 PCT feed grade is a core fermented amino‑acid feed additive widely used in global animal nutrition industry. Produced by microbial fermentation from corn‑based raw materials, this product contains minimum 70% L‑lysine sulphate on dry basis, with effective free lysine content ≥55%. It exists as light‑brown free‑flowing granular particles, featuring low‑dust property for uniform mixing in compound feed and premix production lines.
As the first limiting amino acid for swine and the second limiting amino acid for poultry, lysine cannot be sufficiently synthesized inside animal bodies and must be supplemented from external feed formulas. Compared with L‑Lysine HCl 98.5%, L‑Lysine Sulphate 70% carries multiple natural fermentation by‑products including other minor amino acids, bringing extra nutritional benefits for livestock, poultry and aquaculture species. It delivers comparable bioavailability for non‑ruminant animals while presenting obvious cost‑advantages for large‑scale feed mill procurement.
In practical feed formulation, this additive helps balance dietary amino acid profiles, improve feed conversion ratio, boost daily weight gain, enhance muscle development and meat quality. Feed manufacturers can appropriately reduce crude protein addition by applying L‑Lysine Sulphate 70%, which effectively cuts down overall feed production cost and lowers nitrogen excretion from animal manure for eco‑friendly farming.It is extensively applied in complete feed, premix and concentrate feed for pigs, broilers, layers, ducks, ruminants and aquatic animals. The recommended addition dosage ranges from 0.2%‑0.7% according to animal breeds and growth stages.
Standard export specification meets mainstream feed industry standards, with moisture ≤4.0%, heavy metal and arsenic strictly controlled within international safety thresholds.
