Compatibility & Contraindications
Compatible With
- Amino Acids: Lysine, threonine, tryptophan.
- Vitamins: B-complex vitamins (especially B12 and choline for methionine metabolism), vitamins A, D, E.
- Minerals: Selenium yeast, zinc oxide, calcium carbonate (at recommended levels).
- Acidifiers: Organic acids (e.g., formic acid, propionic acid).
- Antioxidants: Ethoxyquin, natural tocopherols.
Contraindications
- Strong Oxidizing Agents (e.g., potassium permanganate, hydrogen peroxide): Risk of sulfur oxidation, reducing bioavailability.
- Alkaline Substances (e.g., sodium hydroxide, excess limestone): May degrade methionine by altering pH.
- Hygroscopic Additives (e.g., choline chloride): Pre-mix with a dry carrier (e.g., wheat bran) to prevent moisture absorption and caking.
- High Copper/Iron Levels: May chelate methionine, impairing absorption.

Frequently Asked Questions
Q1. What is DL-Methionine Feed Additive?
DL-Methionine is a synthetic essential amino acid used as a feed-grade supplement to optimize animal diets. This product contains ≥99% pure DL-Methionine in crystalline or powder form, providing a bioavailable source of sulfur-containing amino acids critical for protein synthesis, feather/fur development, and metabolic functions in livestock and poultry.
Q2. Why is DL-Methionine supplementation important?
Methionine is the first limiting amino acid in poultry and swine diets. Supplementation improves growth rates, feed efficiency, and carcass quality, supports immune function, and reduces nitrogen excretion. It is especially vital for poultry to prevent feather pecking and promote healthy plumage.
Q3. Is DL-Methionine safe for animals?
Yes, it is safe and non-toxic when used as directed. Over-supplementation may cause amino acid imbalances or metabolic stress (e.g., reduced feed intake). Strictly adhere to recommended levels.
Q4. Can DL-Methionine replace other sulfur-containing additives (e.g., HMTBa)?
Yes, but adjust dosing based on bioavailability. DL-Methionine is directly utilized by animals, while hydroxy analogues (e.g., HMTBa) require metabolic conversion. Consult a nutritionist for equivalency calculations.
Q5. What are the recommended storage conditions and shelf life for DL-Methionine?
DL-Methionine must be stored in a dry, clean environment, protected from moisture, contaminants, direct sunlight, and extreme temperatures. It has a shelf life of 36 months when stored properly under these conditions.
Q6. How should DL-Methionine be mixed and administered?
It should never be administered directly to animals. Instead, it must be uniformly and thoroughly blended into compound feed or premixes to avoid uneven distribution. Recommended dosage ranges are 1.0–2.0 kg/ton for livestock and poultry, 0.3–1.5 kg/ton for swine, and 0.8–3.0 kg/ton for aquaculture.
