Core Product Advantages
Superior Flowability & Anti-Caking: Fluid-bed drying and precise crystallization maintain uniform particle distribution, excellent bulk flowability, and minimal dust formation, preventing clogging in automated feed mill dosing systems.
100% Bioactive L-Isomer: Synthesized through controlled bacterial fermentation, our L-Lysine exhibits near-total intestinal digestibility in livestock, allowing formulators to rely on precise digestible amino acid matrix values.
Full Traceability & Contaminant Control: Every production lot is traceable to its fermentation batch and raw material inputs. Strict monitoring of heavy metals (Pb, As, Cd, Hg) and microbiological limits ensures compliance with EU (EFSA) and US FDA feed safety standards.
Species Application Guidelines
Swine Feed: As the first limiting amino acid in swine diets, L-Lysine HCl supports rapid tissue synthesis in piglet starter feeds and optimizes Feed Conversion Ratio (FCR) while reducing feed costs per kilogram of gain in grower-finisher rations.
Poultry Feed: As the second limiting amino acid in typical corn-soy poultry diets, precise supplementation improves breast muscle yield and feather development in broilers while maintaining egg mass production in layers.
Aquaculture Feed: Offsets the lower lysine bioavailability of plant protein concentrates (such as soy protein concentrate) when reducing fishmeal inclusion in fish and shrimp diets.
Premixes & Concentrates: Uniform particle distribution prevents ingredient segregation during mixing, conveying, and bulk transport.
Quality Assurance & Process Control
Raw Material Screening: Fermentation substrates (corn starch and glucose) are tested for purity and heavy metals before batch release.
Submerged Fermentation: Computer-monitored parameters ensure high yield and isomer purity.
Refining & Fluidized-Bed Drying: Multi-stage filtration and controlled thermal drying keep free moisture <= 1.0% to support physical stability.
Sieving & Magnet Traps: Ensures consistent mesh size, dust control, and total elimination of metallic impurities.
Pre-Shipment Verification: Every batch is tested against NIR, HPLC, heavy metal, and moisture standards before release.
Global Compliance & Documentation Package
Quality System Certifications: FAMI-QS, GMP+, ISO 9001, ISO 22000, and HACCP certified manufacturing lines.
Regulatory Compliance: Fully compliant with EU Feed Hygiene Regulation (EC) No 1831/2003 and applicable FDA feed frameworks.
Standard Documentation Package:
- Technical Data Sheet (TDS)

FAQ
Q: What is the key difference between L-Lysine HCl 98.5% and L-Lysine Sulfate 70%?
A: L-Lysine HCl 98.5% provides a minimum of 78.8% active L-lysine equivalent with high purity and minimal moisture, making it ideal for high-density premixes and space-constrained feed formulations. L-Lysine Sulfate contains fermentation co-products and a lower active lysine content (typically ~55–60% lysine equivalent), requiring higher inclusion rates in the feed matrix.
Q: Can you provide a batch-specific COA prior to shipment?
A: Yes. A representative COA is provided for initial supplier qualification, and a batch-specific COA corresponding to the exact production lot loaded into your container is issued prior to dispatch.
Q: How is material caking prevented during long-distance maritime transport?
A: Caking is prevented by maintaining strict moisture control (<= 1.0%) during fluidized-bed drying, using multi-layer PE moisture-barrier bag liners, and utilizing dry container loading practices.
Q: Are evaluation samples available for laboratory testing?
A: Yes, free evaluation sample kits (100g to 500g) are available for laboratory assay verification and physical inspection for qualified B2B buyers upon request.
Q: Can the product specification be adjusted to match our internal purchasing standard?
A: Yes. We can review your internal technical requirements prior to order confirmation to align parameters such as particle size distribution, moisture limits, or specific heavy metal thresholds.
