DL-Methionine Feed Grade

Whatsapp Order

DL-Methionine Feed Grade is a synthetic, racemic mixture of the amino acid methionine, consisting of equal parts D- and L-isomers. It is an essential sulfur-containing amino acid widely used as a nutritional supplement in animal feed formulations. DL-Methionine plays a critical role in protein synthesis, growth, and metabolic functions in livestock and poultry. This feed-grade quality ensures high purity (minimum 99%) and suitability for inclusion in feed blends to enhance growth performance, improve feed efficiency, and prevent methionine deficiency-related disorders.

DL-Methionine Feed Grade

Primary Uses

Animal Nutrition

Used extensively as a feed additive for poultry, swine, ruminants, aquaculture, and pet food to supply essential sulfur amino acids.
Enhances growth rates, feed conversion ratios (FCR), and overall animal health by preventing methionine deficiency.
Supports feather development in poultry and wool growth in sheep.
Improves immune function and antioxidant status due to its role as a precursor to glutathione.
Balances amino acid profiles in feed to reduce nitrogen excretion and environmental impact.Aquaculture

Provides essential methionine for fish and shrimp diets, promoting growth, survival, and feed utilization.
Helps maintain nitrogen metabolism balance in aquatic species.Feed Manufacturing

Used in premixes and complete feed formulations to optimize nutritional value.
Compatible with various feed processing methods including pelleting and extrusion.

Secondary Uses

Pharmaceutical Industry

Occasionally used in veterinary supplements and formulations to treat methionine deficiency.
Investigated for use in human nutraceuticals and supplements as a source of methionine.Biotechnology & Research

Utilized in cell culture media and fermentation processes requiring sulfur amino acids.
Used in metabolic studies related to sulfur amino acid pathways.
