DL-methionine is used to enrich and balance the diets of fish and to produce mixed feed, premixes, and feed additives.
DL-methionine with the digestibility of about 100 % consists of a mixture of two, D and L, stereoisomers. Animals absorb L-amino acid forms only. And if, for example, D-lysine or D-threonine cannot be used by the organism, D-methionine is metabolized into the L-form. In other words, DL-methionine contains about 50 % of absorbable L-form, and the remaining 50 % become available only after biotransformation. Appearance

Methionine is an essential amino acid which plays an important role in metabolism. It is actively involved in the synthesis of tissue proteins, of a number of vitamins, hormones, and enzymes, due to the presence of a loosely-bound methyl group (-CH3), which can pass to DNA and is a versatile source of methyl groups for all nucleic acids. Furthermore, methionine affects hemoglobin synthesis directly, is required for the synthesis of adrenaline, norepinephrine, cyanocobalamin, creatinine, nicotinic acid amide, and of a number of other substances that have effects on nitrogen, carbon and fat metabolism. Along with cystine and vitamin E, it prevents fatty liver.
With methionine deficiency, the loss of appetite, anemia, muscle atrophy, fatty liver, renal dysfunction, and decreased fertility are observed in animals. The above causes low efficiency of feed utilization. Disturbances of lipid metabolism characterized by fatty infiltration and degeneration of the liver are observed. Due to its high flowability and good mixability, this amino acid is easy to use, safe to handle and can be used at any stage of mixed feed production cycle. Usage
DL-methionine is added to mixed feed through premix. The amount of DL-methionine added to mixed feed depends on the species and age of fish.
Fish products can be used without restrictions. Safety measures
Unloading, storage and loading of feed DL-methionine should be performed in compliance with the general safety measures provided for handling chemicals. In cases of potential contact with the skin or eyes, protective equipment (rubber or plastic gloves, goggles) should be used. Hands and face should be washed before working breaks and after work. In case of contact with eyes, rinse eyes with plenty of water.
Store in a dry place protected from light at the temperature below 30 °С. Shelf life is usually about 5 years. Package
