L-Lysine HCl 98.5% is an industry-standard high-purity crystalline lysine additive with available L-lysine content ≥98.5%. It features high purity, extremely low impurities, excellent water solubility and superior absorption efficiency. It is the preferred amino acid raw material for high-grade compound feed, premix, concentrate feed, special breeding feed and aquafeed. As a universal standard limiting amino acid regulator adopted by feed manufacturers worldwide, it specially compensates amino acid deficiencies in corn and miscellaneous meal-based diets.




Its available lysine content reaches 98.5%. The usable lysine provided per unit dosage is far higher than low-content products such as 70% lysine and lysine fermented meal. It simplifies formula calculation; a small dosage can fill amino acid gaps in diets without introducing extra invalid carriers like crude fiber and ash.
Conventional raw materials including corn, wheat bran, DDGS and wheat meal are inherently deficient in lysine, the primary limiting amino acid for swine, poultry and aquatic animals. High-purity crystalline lysine can accurately adjust the amino acid ratio of feed formulas to achieve the ideal amino acid profile for animals and greatly boost protein utilization efficiency.
When soybean meal prices stay high, supplementation with 98.5% lysine can directly cut the inclusion rate of soybean meal in diets. It drastically lowers the consumption of high-priced protein raw materials and reduces formula costs while maintaining or even improving daily weight gain, feed conversion ratio and egg production performance.
It contains no large amount of plant carriers and low levels of ash and crude fiber, so it will not raise the crude fiber and ash values of finished feed. Its heavy metal, mycotoxin and sulfur contents are extremely low, posing no risk of cumulative poisoning after long-term addition. It meets the standards of high-grade antibiotic-free feed and export-grade feed.
