To prevent deficiency of Methionine. 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 conventional diets.
Methionine is an essential amino acid for all animals, but they do not produce it themselves,
meaning they have to get it from their feed. The methionine content of natural ingredients is
generally low, so to meet the animals’ requirements, additional methionine must be provided
in their feed as a nutritional feed additive.
