Application / Intended Use
DL-methionine is the first limiting amino acid in poultry diets. Feed mills supplement broiler and layer rations at roughly 1-3 kg per tonne to meet requirements without over-feeding crude protein, which reduces nitrogen excretion. It is also used in ruminant rumen-protected form and in pet food.
