Product Description

DL-Methionine 99%

1. Product Overview
Methionine (chemical name: 2-amino-4-methylthiobutyric acid) is one of the essential limiting amino acids for animals, belonging to the sulfur-containing amino acids. As a feed additive, it is primarily used to supplement the deficiency of methionine in natural feed ingredients, improve protein utilization, promote animal growth and development, and enhance production performance.
2. Specifications

• Chemical Name: DL-Methionine

• Content: ≥99%

• Appearance: White to light yellow crystals or crystalline powder

• Solubility: Slightly soluble in water, easily soluble in dilute acids and alkalis

• Packaging: 25 kg/bag (multi-layer moisture-proof packaging)

3. Key Functions

1. Essential Amino Acid Supplement

   • Compensates for methionine deficiency in basal diets (e.g., corn-soybean meal type)

   • Meets the amino acid nutritional requirements of animals, especially poultry and swine

2. Promotes Protein Synthesis

   • Optimizes amino acid balance and improves protein deposition efficiency

   • Enhances muscle growth and improves carcass quality

3. Sulfur-Containing Amino Acid Functions

   • Participates in methyl transfer reactions (acts as a methyl donor)

   • Serves as a precursor for cysteine, promoting feather/hair growth and skin health

4. Improves Production Performance

   • Increases daily weight gain and feed conversion rate in livestock and poultry

   • Enhances egg production rate and egg weight in laying hens

4. Recommended Dosage

Animal Species	Dosage (kg/ton complete feed)	Main Benefits
Broilers	1.5-3.0	Promotes growth, improves feed efficiency
Layers	1.0-2.0	Increases egg production and egg weight
Piglets	1.0-2.0	Reduces stress, promotes growth
Growing-Finishing Pigs	0.5-1.5	Enhances weight gain and lean meat percentage
Aquatic Species	2.0-4.0	Promotes growth, improves body conformation

The dosage is for reference only; the actual dosage will depend on the specific circumstances.
5. Product Advantages

• High Bioavailability: DL-Methionine utilization rate approaches 100%

• Excellent Stability: Minimal loss during feed processing and storage

• Cost-Effective: Low cost per unit of effective amino acid

• Green and Safe: No residues, environmentally friendly

6.Precautions

• Precision Addition: Requires accurate calculation based on animal species, growth stage, and diet composition

• Incompatibilities: Avoid mixing with strong oxidizers, acids, or alkalis

• Storage: Keep sealed in a cool, dry place to prevent moisture absorption and caking

7.Applications

• Poultry feeds (broilers, layers, ducks, turkeys, etc.)

• Swine feeds (starter, nursery, grower-finisher diets)

• Aquafeeds (fish, shrimp diets)

• Ruminant concentrate supplements

• Special economic animal feeds
