Description
DL-Methionine 99%+ Feed Grade (CAS 59-51-8) | Premium Animal Feed Additive
DL-Methionine 99%+ feed grade (CAS 59-51-8) is a high-standard essential amino acid additive tailored for modern animal feed production, widely recognized as an indispensable nutritional fortifier in livestock and aquaculture farming. Manufactured under strict GMP production specifications, our product adopts advanced purification technology to achieve a purity of ≥99.0%, with controlled moisture ≤0.5%, heavy metal (Pb) content ≤10mg/kg and arsenic (As) content ≤2mg/kg, ensuring zero safety hazards for animal feeding and fully meeting global feed grade quality benchmarks. The product shows stable optical rotation at ±0.5°, with fine white crystalline powder appearance, good fluidity and easy dispersion, which can be evenly mixed with various feed raw materials without agglomeration.
Functionally, DL-Methionine plays a decisive role in animal growth and development. It participates in protein synthesis, fat metabolism and antioxidant reactions in animals, effectively solving the problem of unbalanced feed nutrition. Long-term scientific supplementation can significantly improve feed conversion ratio, reduce feed waste, shorten animal growth cycles, and increase lean meat rate and egg production performance. It is universally applicable to poultry, swine, cattle, sheep, aquatic products and pet feed, adapting to all mainstream breeding scenarios worldwide.
Supplied by Linkwin, this Chinese-origin DL-Methionine features stable quality and sufficient bulk supply. We provide complete official certification documents including COA and MSDS to support customer quality verification and customs clearance. With flexible FOB and CIF pricing terms, we offer transparent and competitive bulk prices for global clients. Adhering to strict quality control systems, we deliver high-purity, safe and efficient feed additives to help global breeding industries reduce costs and improve breeding benefits.
