Key Product Advantages
Industry-Leading Purity for Precision Formulation
Your feed requires exact amino acid ratios. Our 98.5% purity and 78.8% lysine density deliver the highest concentration available, allowing you to optimize your nutritional matrix with confidence.
Maximum Bioavailability
The product offers nearly 100% metabolic utilization. Unlike lysine bound in protein sources, this crystalline form is immediately available for protein synthesis in your animals.
Superior Processing Stability
You can trust this product through standard pelleting processes up to 85°C. It maintains excellent flowability and uniform mixing in premixes, ensuring consistent distribution throughout your feed batches.
Complete Traceability & Quality Assurance
Every bag links to specific fermentation batch records and QC data. We test each production run using HPLC and ion-exchange chromatography, ensuring you receive documented quality with every shipment.
High Solubility for Versatile Applications
Whether you produce pelleted feed or liquid feeding systems, this product dissolves readily. This flexibility supports various production methods without formulation adjustments.

Swine Production
In your pig operations, L-Lysine Monohydrochloride 98 drives lean meat yield and Average Daily Gain (ADG). You can formulate low-protein diets while maintaining optimal lysine-to-energy ratios, reducing nitrogen excretion by up to 30% and improving finishing efficiency.
Poultry Nutrition
For broiler and turkey generation, this amino corrosive improves breast meat surrender and makes strides Bolster Transformation Proportion (FCR). In high-density situations where intestine wellbeing things, exact lysine supplementation bolsters steady execution over your flocks.
Aquaculture Diets
Fish and shrimp details advantage essentially when you supplant fishmeal with plant proteins. This item compensates for lysine lack in soybean and cottonseed supper, guaranteeing quick development and legitimate skeletal advancement. Its agreeability and filtering resistance make it perfect for oceanic bolster manufacturing.
We actualize thorough testing conventions that specifically affect your creature performance:
Assay Confirmation: HPLC and ion-exchange chromatography affirm ≥98.0% immaculateness in each batch.
Moisture Control: Misfortune on Drying ≤1.0% anticipates clumping and microbial development amid storage.
Isomeric Immaculateness: Particular revolution testing guarantees as it were the healthfully dynamic 'L' shape is display; 'D' shapes contribute zero dietary value.
Heavy Metal Screening: ICP-MS testing confirms Arsenic <2mg/kg and Lead <10mg/kg, meeting the strictest global safety regulations.
Process Quality Indicators: Residue on Ignition ≤0.3% and Ammonium Salt content measurements confirm superior fermentation and crystallization refinement.
These controls guarantee your product withstands long-term storage and high-shear mixing without degradation.
Store in cool, dry, ventilated distribution centers. The item is somewhat hygroscopic, so keeping up PE-lined pack judgment is basic for protecting flowability.
Keep absent from coordinate daylight and dampness sources. Legitimately put away fabric keeps up full strength for 24 months from generation date.
Handle with standard bolster process safeguards. Whereas non-hazardous, utilize tidy veils amid bulk dealing with to anticipate respiratory irritation.
13+ A long time Fabricating Encounter: Our devoted chemical generation base works beneath strict ISO 9001 and REACH compliance standards.
Stable Supply Chain: With over 5,000 tons stock capacity and computerized generation lines, we fulfill orders consistently—from trial clusters to full holder loads.
Custom Detailing Back: Our in-house R&D research facility gives 24-hour custom improvement administrations when your applications require particular molecule sizes or specialized blends.
Global Coordinations Greatness: We serve clients in 50+ nations with 99.5% on-time conveyance. Our proficient trade bundling and coordinations coordination guarantee your orders arrive intaglio and on schedule.
Technical Organization: Experienced chemical engineers and sustenance pros give progressing back from starting meeting through generation optimization.

Q: What is the distinction between the item and L-Lysine Sulfate?
A: L-Lysine Monohydrochloride contains roughly 78% free lysine compared to Sulfate's 55%. It has less aging by-products and higher virtue, making it best for high-density diets where accuracy matters.
Q: How does this item perform amid pelleting?
A: It remains profoundly steady beneath standard pelleting temperatures and weights. Be that as it may, over the top warm over 100°C in the nearness of lessening sugars can trigger the Maillard response, decreasing lysine accessibility. Keep pelleting temperatures inside suggested ranges.
Q: Is the bioavailability diverse from normal protein sources?
A: No. The item is chemically indistinguishable to lysine in characteristic proteins. It's really more edible since it doesn't require enzymatic breakdown from a protein matrix—your creatures utilize it immediately.
Q: How ought to I anticipate caking amid storage?
A: Keep in cool, dry, ventilated regions. Since the item is marginally hygroscopic, guarantee PE-lined sack judgment. Once opened, reseal instantly or exchange to moisture-proof containers.
Q: Why does pH esteem matter?
A: The pH (ordinarily 5.0–6.0 in 10% arrangement) influences solidness and compatibility with other micro-ingredients in your premix, especially vitamins and minerals. Our steady pH extend guarantees unsurprising behavior in complex formulations.
Q: Can I utilize this item in fluid bolstering systems?
A: Completely. The tall solvency makes it perfect for fluid nourishing applications. It breaks down totally without taking off buildups that may clog conveyance systems.
Q: What documentation do you give with shipments?
A: Each shipment incorporates Certificate of Investigation (COA), group traceability records, MSDS, and compliance Certifications. We can give extra documentation for administrative necessities in your nation.
