Overview
L-Lysine Hydrochloride is an essential amino acid widely used as a feed additive to improve protein synthesis and support optimal growth in poultry, swine, ruminants, and aquaculture species. As animals cannot synthesize lysine on their own, supplementation is necessary in modern feed formulations, especially in grain-based diets naturally low in lysine.
Our L-Lysine HCl is produced according to GB 34466-2017, ensuring consistent quality, high purity, and excellent digestibility for improved feed efficiency.

Applications & Dosage
Applications
- Improves protein synthesis and nitrogen utilization.
- Enhances growth performance and feed conversion ratio.
- Corrects lysine deficiencies in cereal-based feed formulas.
- Supports muscle development and metabolic functions.
Recommended Dosage
- Poultry: 0.1–0.3% of total feed.
- Swine: 0.2–0.45% depending on growth stage.
- Aquaculture: 0.3–1.0% according to species and formula.
- Ruminants: Used in bypass-protected forms as required.
Dosage should be adjusted according to diet composition, nutrient requirements, and feed formulation objectives.
Product FAQ
1. What is L-Lysine Hydrochloride used for in animal feed?
L-Lysine HCl is an essential amino acid supplement used to correct lysine deficiencies in cereal-based diets. It improves protein utilization, supports muscle development, and enhances growth performance in poultry, swine, ruminants, and aquaculture species.
2. What are the benefits of adding L-Lysine HCl to feed formulations?
Adding L-Lysine HCl boosts feed conversion efficiency, increases growth rates, optimizes nitrogen utilization, and reduces formulation costs by allowing more flexible use of low-lysine raw materials such as corn or sorghum.
3. Is feed-grade L-Lysine Hydrochloride the same as L-Lysine?
L-Lysine HCl is the highly stable and commonly used commercial form of lysine for feed manufacturing. It contains ≥78.8% available lysine and provides better handling, storage stability, and formulation accuracy than free L-Lysine.
4. Is L-Lysine Hydrochloride safe for all livestock species?
Yes. Feed-grade L-Lysine HCl is widely used in poultry, swine, ruminant, and aquaculture diets and is considered safe when included at recommended levels according to nutritional guidelines.
5. What is the typical purity of your L-Lysine HCl?
Our product has a purity of ≥98.5% L-Lysine HCl (dry basis) and meets the requirements of GB 34466-2017, ensuring consistent quality and high bioavailability.
