L-lysine Sulphate

Comparison

L-Lysine Sulphate 70% (55% Pure Lysine): Includes 55% free L-Lysine plus residual fermentation biomass (additional amino acids, phosphorus, and organic matter). Reduces raw material cost per unit of effective lysine in swine and poultry diets.

L-Lysine HCl 98.5% (78.8% Pure Lysine): Higher pure amino acid density, lower bulk weight, zero sulphate load. Suited for space-restricted concentrate pre-mixes.

Integration

Electrolyte Balance (dEB): Formulators must account for the dietary sulphate content (SO₄²⁻) when calculating the dietary electrolyte balance (Na⁺ + K⁺ - Cl⁻) to avoid metabolic acidosis in high-density poultry diets.

Biomass Value: The co-produced biomass yields approximately 10-15% additional nutritional solids, contributing trace amino acids and bio-available organic phosphorus, reducing the need for added dicalcium phosphate.

Certifications: FAMI-QS certified, ISO 9001:2015, ISO 22000, HACCP compliant manufacturing site.

Contaminant Controls: Every batch undergoes testing for heavy metals (Pb, As, Cd, Hg), dioxins, PCBs, and mycotoxins (Aflatoxin B1, Zearalenone) in accordance with EU Regulation (EC) No 1831/2003 and FDA animal feed safety guidelines.

Pathogen Control: Thermal treatment during spray-drying ensures negative results for Salmonella spp. and E. coli per 25g sample.

Retained Samples: Standard retained samples are stored under controlled environmental conditions for 24 months past the manufacturing date.

Lot Numbering: Each 25kg bag or super sack features a machine-readable barcode linked to raw material fermentation batches, production time, and final analytical CoA records.
