?CAS No.: 63-68-3
?Appearance (Appearance): white flaky crystal?or?powder?
DL-Methionin, one of essential amino acids and sulfur amino acids, is the first limiting amino acid in poultry, and probably also in high-yielding cows, and is the second?or?third limiting amino acid in pigs fed convertional diets.

It participates in synthesis of tissue proteins, vitamins, enzymes and hormones taking part in nitrogen, carbohydrate and fat metabolisms, and it is the important source of methyl groups for synthesis of all nucleic acids, as well as the sulfur source for sulfonic compounds.
It is frequently used in the feed industry to meet the requirements of target animals and fish, in order to maximize production performance and reduce nitrogen emission. Usually, diets for piglets and growing pigs can show a considerable deficiency in Methionine, especially when formulated to achieve low nitrogen excretion for ecological reasons. Therefore, such a deficiency must be conveniently compensated for by adding DL-Methionine in animal diets.
