L-Methionine is an essential amino acid that is very important for animals.
It is the 1st limiting amino acid in poultry and aqua feed,
and the 2nd limiting amino acid in swine feed.
(The order of limiting amino acids can differ depending on environment or feed ingredients.)
L-Methionine VS DL-Methionine
DL-Met is produced by synthetic process, while L-Met is produced by fermentation process.
L-Met is a key in utilization for intestinal development and digestive tract due to the
higher bioavailability than DL-Met. DL-Met must be converted to L-Met to mobilize in the body.
Function of L-methionine
L-Methionine not only serves as a constituent of skeletal muscle protein
but also optimizes the development of digestive tract and growth performance. Physiological function
of L-methionine includes antioxidant effect, heat stress reduction,
fatty liver inhibition and liver detoxification because of the metabolic products like glutathione.
Furthermore, it has a function of optimizing muscle mass,
feather development and maintaining egg production in animals.
