DL-Methionine is a key essential amino acid widely used in animal feed to support healthy growth and optimize production performance. Since animals cannot synthesize methionine, it must be supplemented externally. Our high-purity DL-methionine effectively enhances the nutritional value of animal feeds, suitable for pigs, poultry, ruminants, and aquaculture.

Description |
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. DL-Methionine 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. DL-Methionine 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. |
