Description

Sodium 2-Hydroxy-4-(Methylthio)Butyrate is the sodium salt of the hydroxy analogue of methionine, a critical amino acid. This compound serves as a highly bioavailable source of methionine activity, essential for protein synthesis and metabolic functions in livestock and poultry. It is a vital feed additive for the global animal nutrition industry, where consistent quality and reliable supply are paramount for optimizing feed efficiency and animal health.

Application

• Animal Feed Additive: Primary use as a methionine source in poultry, swine, and aquaculture diets to support growth, feathering, and overall health.
• Ruminant Nutrition: Used in bypass or protected forms to supplement methionine in dairy cow rations, supporting milk protein synthesis and metabolic health.
• Pet Food Fortification: Incorporated into premium dog and cat food formulations to ensure complete and balanced amino acid profiles.
• Aquafeed: Essential component in shrimp and fish feed to meet specific methionine requirements for optimal growth and feed conversion ratios.
• Pre-mix and Concentrate Manufacturing: A key ingredient for feed manufacturers producing vitamin-mineral pre-mixes and protein concentrates.
• Biochemical Research: Used in laboratory settings as a standard or reagent in studies involving amino acid metabolism and animal science.
