Compatibility & Contraindications
Compatible With
- Amino Acids: Leucine, valine, lysine, methionine.
- Vitamins: B-complex vitamins (especially B6 for BCAA metabolism), vitamins A, D, E.
- Minerals: Calcium carbonate, phosphates, zinc oxide (at recommended levels).
- Acidifiers: Organic acids (e.g., citric acid, lactic acid).
- Probiotics/Prebiotics: Bacillus subtilis, yeast-based products.
Contraindications
- Alkaline Substances: (e.g., sodium bicarbonate, excess limestone) May degrade isoleucine by altering pH and reducing absorption.
- Strong Oxidizers: (e.g., potassium permanganate, hydrogen peroxide) Risk of oxidative degradation.
- Hygroscopic Additives: (e.g., choline chloride) Pre-mix with a dry carrier (e.g., corn gluten meal) to prevent moisture absorption and clumping.
- High Iron/Copper Levels: May chelate isoleucine, impairing bioavailability.

Frequently Asked Questions
1. What is L-Isoleucine Feed Additive?
L-Isoleucine is an essential branched-chain amino acid (BCAA) used as a feed-grade supplement to optimize animal diets. This product contains ≥98% pure L-Isoleucine in crystalline or powder form, supporting muscle protein synthesis, energy metabolism, and immune function in livestock and poultry.
2. Why is L-Isoleucine supplementation important?
Isoleucine is a limiting amino acid in plant-based feeds, particularly for monogastric animals. Supplementation improves growth performance, enhances feed efficiency, reduces muscle breakdown during stress, and supports recovery in high-intensity production systems.
3. Is L-Isoleucine safe for animals?
Yes, it is non-toxic and safe when used as directed. Over-supplementation may disrupt BCAA balance (leucine:isoleucine:valine ratios) or cause metabolic stress. Strictly follow recommended levels.
4. Can L-Isoleucine replace other amino acid supplements?
No—it must be balanced with leucine and valine (other BCAAs) and essential amino acids (e.g., lysine, methionine). Imbalanced ratios may reduce growth performance or cause health issues.
5. What are the recommended dosages of L-Isoleucine for different species?
Recommended dosages vary by animal type: General Use is 0.005%–0.3% of total feed; Swine requires 0.2–0.7 kg/ton of feed; Poultry requires 0.1–0.4 kg/ton of feed; and Aquaculture requires 0.3–0.8 kg/ton of feed. Adjustments should be made according to species-specific requirements or veterinary guidance.
6. How should L-Isoleucine be stored and what substances should be avoided?
Store L-Isoleucine in a cool, dry, well-ventilated area protected from direct sunlight and moisture. It is prohibited to store it with toxic or hazardous substances. Avoid mixing directly with alkaline substances (e.g., sodium bicarbonate, excess limestone), strong oxidizers, high iron/copper levels, and hygroscopic additives (e.g., choline chloride) without a dry carrier.
