Feed additive Essential Amino Acids Power DL Methionine for feed,
Methionine is a "framework" amino acid of biosynthesis protein,
is one of the essential amino acids in the growth of livestock
animals, has a strong role in regulating animal metabolism,
is widely used in feed, pharmaceutical, food and cosmetics fields.
In the feed industry, the amount of methionine ranks first in
as a nutrition fortifier of the feed, an additive to make up the
amino acid balance. Add 1kg methionine in feed,
is equivalent to the nutritional value of fish meal 50kg.
Normally0.05% to 0.2% Methionine is added in the feed.
In medicine, methionine can be used as the main ingredient of the
amino acid infusion and compound amino acid,
can also be used for synthetic medicinal vitamins,
it lipotropic effect can be used for the production of
In the food industry, the methionine is used for healthcare food,
as a nutritional supplement.
