What is L-methionine

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.)

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.

What is L-lysine

L-Lysine is the reference amino acid in modern animal nutrition.
It must be provided in all types of animal feed to ensure optimal
performance.
Especially, L-lysine is an essential amino acid for monogastric animals.
It cannot be synthesized by the organism and needs to be provided with
the feed.
Therefore, supplementation of free L-lysine is the 1st limiting amino acid in
swine feed and the 2nd limiting amino acid in broiler feed and aquatic animal feed.
(The order of limiting amino acids can differ depending on environment or
feed ingredients.)

Functions of L-lysine

It is the basic but most important amino acid that forms the basis
for the ‘Ideal protein model’ in animal feed. Especially, L-lysine optimizes
animal growth performance, synthesizes muscle proteins, and aids in calcium resorption.

What is L-valine

In global feed grade amino acids market, valine market has shown the
high growth
rate over the last few years (CAGR 48% during 2015~2020).

This rapid market growth is coupled with a corresponding global feed
trend of reducing
excess dietary crude protein (CP); supplementation of L-valine can allow for
a further reduction
of dietary CP level and help to reduce the nitrogen excretion while
minimizing feed cost.

Functions of L-valine

L-Valine is one of the BCAAs (Branched-chain Amino Acids) along with
isoleucine and leucine.
It is essential for the appropriate tissue regeneration and muscle
development.
Also, supplementing L-valine is one way to balance low-protein diets
effectively.

What is L-arginine

L-Arginine, an essential amino acid for poultry and aquatic animals and
conditionally
essential for swine, is necessary for animals’ growth and reproduction.
In particular, poultry and aquatic animals are not able to synthesize Larginine
themselves, and therefore depend on dietary L-arginine to meet their needs
for protein
synthesis and other functions. It is the 4th limiting amino acid in broiler and
aqua feed and the 7th limiting amino acid in swine feeds.
(The order of limiting amino acids can differ depending on environment or
feed ingredients.)

Functions of L-arginine

L-Arginine is related to production of nitric oxide, urea, polyamine
(putrescine, spermidine, and spermine), creatine, and amino acids (proline
and glutamate).
Especially, L-arginine is the only amino acid that can directly synthesize nitric
oxide.
Nitric oxide mainly works on blood vessel relaxation and this helps improve
the health of animals.
