The feed-use amino acids market pioneer
AJINOMOTO EUROLYSINE S.A.S. has produced and sold L-Lysine since 1976, L-Threonine since 1987 and L-Tryptophan since 2000.
In 2009, AJINOMOTO EUROLYSINE S.A.S. is again the first to launch the production of L-Valine for feed-use.
Our amino acids are produced by the fermentation of raw materials from agriculture such as beet sugar, beet molasses or starch hydrolysates from cereals.
Ajinomoto Eurolysine's highlights
-
Update your ideal amino acid profile!
A balanced amino acid profile optimises the expression of the genetic potential of animals.
The trial results from our experimental program and the carrying out of a meta-analysis allowed the amino acids profile (ideal protein) recommended by AJINOMOTO EUROLYSINE S.A.S. to be updated.
-
Tryptophan in piglet nutrition
A meta-analysis to estimate the tryptophan requirement!
A new statistical method using 40 dose-response studies was performed to confirm the tryptophan requirement in piglets.
38 publications in one information bulletin!
The most recent literature about the role of dietary tryptophan in piglet appetite, growth, behaviour and immunity.
-
L-Valine: Break through the feed optimisation barrier!
AJINOMOTO EUROLYSINE S.A.S.'s L-Valine Feed Grade is a major innovation for the feed industry.
Used to meet the digestible valine requirement of animals, L-Valine Feed Grade is a new ingredient that brings further options for optimising feed formulations that have not been available before.

Threonine in pigs and broiler
A 20 pages synthesis document about the requirement and the roles of threonine!
This bulletin describes the effect of the age and sanitary status on animal requirements as well as the importance of threonine in gut functions and immunity.
EvaPig®
EvaPig® is a calculator of energy, amino acid and phosphorus values of ingredients and diets for growing and adult pigs.
Bulletins
The results obtained from our experimental program and from the literature are compiled and presented in our technical bulletins.
Feedstuff amino acid database
Raw materials analyses feed a database which is compiled to supply information on the variations in amino acids content of ingredients.
Estimating amino acid needs
Estimating amino acid requirements through dose-response experiments in pigs and poultry - Protocol and results interpretation.
Environment-friendly
The use of our amino acids feed-grade allows reducing the nitrogen pollution from husbandry, combating global warming and eutrophication.
