Methionine is the first limiting amino acid in poultry nutrition. DL-methionine is a sulfur-containing amino acid composed of 50% D-methionine isomer and 50% L-methionine isomer. Birds can utilize both the D and L forms; after conversion of the D form to L, it is used by the bird.

Methionine is a precursor of sulfur-related compounds such as homocysteine, taurine, and glutathione, and it plays an important role in transmethylation reactions as a methyl-group donor.

Key functions of methionine in broilers include increasing muscle mass, supporting feather growth, and improving overall performance and feed conversion ratio (FCR).
