Description
What is Feed Grade L-Lysine?
Feed Grade L-Lysine is a nutritional amino acid supplement primarily composed of L-lysine hydrochloride (C₆H₁₄N₂O₂·HCl) or L-lysine sulfate, widely used in animal nutrition. As one of the essential amino acids that animals cannot synthesize on their own, lysine plays a vital role in protein synthesis, tissue repair, and metabolic regulation. It is typically processed into powder or granular form to ensure optimal bioavailability, easy handling, and feed formulation compatibility.
Core Features
1. Composition & Purity
The main component is L-lysine, with purity ≥98.5% for L-lysine HCl (or ≥70% for L-lysine sulfate). It is standardized to meet feed-grade requirements (e.g., GB/T 34466-2017 for feed amino acids) with strict control of heavy metals (lead, arsenic, cadmium) and microbiological safety.
2 Physical Form
Available as free-flowing fine powder or granules (20-80 mesh, or custom mesh sizes), with:
Light yellow to off-white appearance
High solubility in water
Low dust and static, improving feed plant cleanliness
Excellent mixing performance in both premix and complete feed
Stability & Functionality
Essential Amino Acid for Growth: ≥98.5% purity for HCl or ≥70% for sulfate, with fast absorption
Certified Quality: Complies with GB/T, FAMI-QS, GMP+, and ISO standards
Versatile Formulation: Works in premix, concentrate, and TMR feeds for swine, poultry, ruminants, aquaculture

L-Lysine HCl 98.5% for Animal Feed
Amino Acid Feed Additive
Application
Swine & Poultry Nutrition
L-lysine is a limiting amino acid in swine and poultry diets. Supplementing lysine corrects amino acid imbalance, promotes muscle development, and improves nitrogen utilization.
Key Role: Boosts protein synthesis, improves growth rate, and enhances feed efficiency.
Ruminant Feeds (e.g., Dairy & Beef Cattle)
Bypass lysine forms (protected lysine) are used to ensure delivery to the small intestine, especially in high-producing dairy cows.
Key Role: Supports milk protein synthesis, maintains rumen health, and improves reproductive performance.
Aquaculture
Fish and shrimp require high-quality protein; L-lysine ensures essential amino acid balance in plant-protein-rich feeds.
Key Role: Enhances growth performance, improves feed utilization, and strengthens disease resistance.
Pet Food & Specialty Animals
Lysine is included in dog, cat, and exotic animal diets for immune function and muscle development.
Key Role: Maintains lean body mass, supports metabolism, and aids immune defense.
Applications & Solutions
Animal feed
Pigs (especially finishing pigs and sows), poultry (such as chickens, ducks, and geese), aquatic animals (such as fish and shrimp), and ruminants (such as dairy cows, beef cattle, and sheep).
Swine & Poultry Nutrition

FAQ
What is L-lysine and why is it essential in animal feed?
L-lysine is one of the 10 essential amino acids animals cannot synthesize. It ensures proper protein formation, hormone production, and tissue repair. Feed-grade lysine provides a cost-effective way to balance amino acid profiles, especially in corn/soy-based diets.
How is lysine HCl different from lysine sulfate?
Yes. Crude protein alone does not guarantee balanced amino acid profiles. Supplementing with lysine allows for protein reduction in diets without compromising growth, leading to lower feed cost and reduced nitrogen emissions.
Is lysine supplementation necessary if protein content is
90% ethyl xanthate is generally superior for both industrial use and transportation compared to lower purity products, offering higher active content for more efficient dosing,
better flotation performance consistency, and improved storage stability. While it comes at a slightly higher cost, these advantages typically outweigh the price difference.
The higher purity formulation does require more careful handling during transport due to increased CS₂ gas emission risks when exposed to moisture or heat, necessitating
proper sealed packaging and temperature control. For most mining applications, the operational benefits of 90% purity justify its selection, though lower grade
alternatives (80-85%) may be considered for simpler ore processing where cost is the primary concern.
How is lysine applied in feed processing?
Easily premixed into compound feeds or concentrates
Compatible with extrusion and pelleting
Stable under high-temperature conditions during feed processing (loss rate <2% during pelleting at 85–95℃)
