Ajinomoto launched its feed grade amino acid business in 1965 and has since built an international production and supply network. The head office of the Animal Nutrition Department is located in Tokyo. Ajinomoto has five manufacturing bases for feed grade amino acid production around the world. They are in Thailand, China, France, Brazil and U.S.A. Now Ajinomoto is producing of feed grade amino acids L-Lysine, L-Threonine, L-Tryptophan and L-Valine.

In 1986, Ajinomoto Co., (Thailand) Ltd. established a lysine producing plant in Pathum Thani province of Thailand. The plant was awarded the ISO 14001 (September 2001) and ISO 9001:2000 certification (July 2002) by SGS International Certification Services.
Type of products
L-Lysine Monohydrochloride 98.5% Feed Grade
LysineLysine is the first limiting amino acid in feeds for pig and the second for poultry. The amount of lysine ingested on a daily basis has a direct influence on animal growth performances as this amino acid mainly serves to deposit body protein. Thus, adjusting the dietary lysine concentration according to the animal growth potential and its feed intake capacity makes it possible not only to optimize growth but also to optimize feed efficiency.
Moreover, in broiler chicken, there is a direct link between daily lysine supply and the development of certain muscles such as breasts. Therefore, adjusting lysine content enhances the value of meat cuts in case of further processing.
L-Lysine also makes it possible to limit the use of protein-bound lysine which is contained in vegetal protein such as soybean meal; this in turn reduces dietary protein levels and, as a consequence, reduces nitrogen excretion from animal husbandry in the environment. Moreover, as L-Lysine is 100% digestible, the animal can utilize is far greater than that of protein-bound lysine from vegetal protein.
Physical appearance is white to pale yellow crystals.
L-Threonine 98.5% Feed Grade
Threonine is usually the second limiting amino acid for pig and the third for poultry. Like lysine, to which it is complementary, threonine is an essential amino acid for body protein deposition and growth. Thus, deficiency in threonine affects the utilization of dietary lysine and consequently animal growth.
Moreover, threonine is involved in a certain number of specific physiological processes. It is notably involved in digestion and immunity. Thus, a deficiency in threonine leads to disorders in the digestive physiology which can, in turn, increase the frequency of digestive problems. As a consequence, total threonine requirement varies depending on the relative importance of these different functions. It is therefore important to determine the threonine requirement which corresponds to each physiological stage in order to improve the balance and efficiency of feeds.
Physical property is chrystalline solid.
Physical appearance is white to off-white granule.
Tryptophan is an essential amino acid: it has to be supplied to animals through their feed in sufficient amounts to cover their requirement. Dietary supply through feed materials can be insufficient; supplementation is then needed.

"L-Tryptophan 98% Feed Grade" is used to supplement feeds in order to meet the digestible tryptophan requirement of animals. It is particularly suitable for young pigs, because it helps to improve feed intake, growth rate and feed efficiency.
 
Higher feed intake
Maximising feed intake is a practical challenge, especially in young pigs and in lactating sows. At both physiological stages, supplementing a deficient diet with tryptophan has been proven to enhance feed intake. This effect should be related to the fact that this amino acid is involved in appetite regulation in animals.
 
Higher growth rate and feed efficiency
Tryptophan supplementation aims at meeting the nutritional requirement of the animal. Recent trials have shown that a dietary Tryptophan : Lysine (Trp:Lys) ratio of 22% optimizes piglet performance. High body weight gain and feed efficiency levels result from the combination of higher feed intake and improved dietary amino acid balance (ideal protein).
 
Performance under poor sanitary conditions
Tryptophan is also involved in the immune response. The activation of the immune system may create a specific requirement. Experiments comparing good and poor environments have shown that the increase in feed intake and growth rate obtained with higher dietary tryptophan contents is higher in a poor sanitary environment. These results emphasize the benefits of upgrading Trp:Lys levels up to 22% in practical farming conditions.
Physical description is white to pale yellow crystals.
