Usage & Dosage
Application: Uniformly blend into compound feed or premixes.
Recommended Dosage:
- General Use: 0.1–1.0 kg per metric ton of feed.
- Swine: 0.1–0.5 kg/ton of feed
- Poultry: 0.05–0.3 kg/ton of feed
- Aquaculture: 0.2–0.6 kg/ton of feed
*Adjust dosage according to species-specific requirements or veterinary guidance.
Additional Notes / Precautions: Ensure thorough mixing to avoid segregation.
Compatibility & Contraindications
Compatible With
- Amino Acids: Lysine, methionine, threonine.
- Vitamins: B-complex vitamins (especially B6, which aids tryptophan metabolism), vitamins A, D, E.
- Minerals: Phosphates, calcium carbonate, selenium yeast (at recommended levels).
- Acidifiers: Organic acids (e.g., fumaric acid, citric acid).
- Antioxidants: Ethoxyquin, natural extracts (e.g., tocopherols).
Contraindications
- Alkaline Substances: (e.g., sodium bicarbonate, excess limestone) May reduce bioavailability by altering pH and degrading tryptophan.
- Strong Oxidizers: (e.g., potassium permanganate, hydrogen peroxide) Risk of chemical breakdown.
- Hygroscopic Additives: (e.g., choline chloride) Pre-mix with a dry carrier (e.g., soybean meal) to prevent moisture absorption and clumping.
- High Copper/Zinc Levels: May chelate tryptophan, reducing absorption.
- Direct UV Exposure: Degrades tryptophan; store in opaque or light-resistant packaging.
Product Details
FAQs
Q
1. What is L-Tryptophan 98% Feed Additive?
L-Tryptophan is an essential amino acid used as a feed-grade supplement to optimize animal diets. This product contains 98% pure L-Tryptophan in crystalline or powder form, supporting protein synthesis, immune function, and stress management in livestock and poultry.
Q
2. Why is L-Tryptophan supplementation important?
Tryptophan is a limiting amino acid in many plant-based feeds. Supplementation improves growth performance, reduces aggression in animals, enhances gut health, and serves as a precursor for serotonin and melatonin, promoting calm behavior and improved welfare.
Q
3. Is L-Tryptophan safe for animals?
Yes, it is safe and non-toxic when used as directed. Over-supplementation may disrupt amino acid balance or cause serotonin-related effects (e.g., lethargy). Follow recommended levels strictly.
Q
4. Can L-Tryptophan replace other amino acid supplements?
No—it is designed to complement lysine, methionine, and threonine. Balanced amino acid profiles are critical; never use tryptophan as a sole supplement without professional guidance.
Q
5. How should L-Tryptophan Feed Additive be stored to maintain its shelf life?
It must be stored in a dry, well-ventilated area under normal ambient conditions. Keep the packaging tightly sealed and avoid direct exposure to sunlight, moisture, or extreme temperatures to prevent degradation.
Q
6. What are the key contraindications when mixing L-Tryptophan?
Avoid direct contact with alkaline substances (such as sodium bicarbonate), strong oxidizers, high levels of copper or zinc, and direct UV light, as these can degrade the amino acid or reduce its bioavailability.
