Functions
L-Lysine Sulphate is essential for:
Growth Promotion
Enhances protein synthesis and muscle development in animals.
Feed Efficiency
Improves nutrient absorption and feed conversion ratio.
Essential Amino Acid Supplement
Addresses lysine deficiency in plant-based diets.
Immune Support
Strengthens disease resistance and overall metabolic functions.
Compatibility & Contraindications
Compatible With:
- Amino Acids: Methionine, threonine, tryptophan.
- Vitamins: Vitamins A, D, E, K, and B-complex.
- Minerals: Calcium carbonate, phosphates, zinc oxide.
- Acidifiers: Organic acids (e.g., citric acid, formic acid).
- Antioxidants: Ethoxyquin, BHA/BHT.
Contraindications
- Alkaline Substances (e.g., sodium bicarbonate, limestone in excess): May reduce lysine bioavailability due to pH interactions.
- Strong Oxidizers (e.g., potassium permanganate): Risk of chemical reactions.
- High Copper Sulphate Levels: May form complexes, reducing lysine absorption.
- Choline Chloride: Avoid direct mixing without a carrier (hygroscopicity may cause clumping).
- Moisture or Humid Environments: May cause caking; ensure proper storage and mixing.
Usage & Dosage

FAQs
Q1
What is L-Lysine Sulphate?
L-Lysine Sulphate is a feed-grade amino acid supplement derived from fermentation. It contains L-Lysine in sulphate form and is equivalent to 70% L-Lysine Hydrochloride (HCl) in biological activity. It is used to balance amino acid profiles in animal diets, promoting growth, feed efficiency, and protein synthesis.
Q2
Why use L-Lysine Sulphate instead of L-Lysine HCl?
L-Lysine Sulphate offers similar benefits to L-Lysine HCl but in a cost-effective sulphate form. It is ideal for feed formulations requiring moisture stability and reduced chloride content. The "70% equivalence" refers to its lysine content relative to L-Lysine HCl (e.g., 1 kg of L-Lysine Sulphate provides lysine equivalent to 0.7 kg of L-Lysine HCl).
Q3
Which animals can benefit from this product?
It is suitable for poultry (broilers, layers), swine, aquaculture species, and ruminants. Always consult a nutritionist for species-specific dosing.
Q4
Is L-Lysine Sulphate safe?
Yes, it is safe when used as directed. Follow recommended guidelines to avoid over-supplementation, which may disrupt amino acid balance.
Q5
Can it replace L-Lysine HCl entirely?
Yes, but adjust the dosage to account for the 70% equivalence. For example, if a formula requires 1 kg of L-Lysine HCl, use ~1.43 kg of L-Lysine Sulphate (1 kg ÷ 0.7).
Q6
Does it interact with other feed additives?
It is compatible with most vitamins, minerals, and amino acids (e.g., methionine, threonine). Avoid mixing with strong oxidizing agents, alkaline substances, or high levels of copper sulphate.
