AMINO ACIDS (Methionine)


DL-Methionine is synthesize from petrochemical raw materials using an environmentally friendly patented proprietary process by the feed additives business of SWISS CHEMIE,known as the carbonate process.

This Proven complex,system result in a high quality product without the formation of waste salt,while largely avoiding pollution by waste air and water.

USE :-

Particularly for use in monogastrics. DL-Methionine Feed grade ensures the  adequate supply of sulfur amino acids,especially of the essential methionine. Because of mrthionine being rst-limiting in typical poultry diets its use has been well established for many years. Additionally,diets for piglets and growing pigs can show a considerable deciency in methionine. especially when formulated to achieve low nitrogen excretion for ecological reason. Such a deciency can be conveniently  compensated for using DL-Methionine Feed Grade.

Lysine HCL

L-Lysine HCl is one of the most widely used amino acid. It is an essential amino acid required in the diets of swine, poultry and most other animal species. L-Lysine HCl is frequently the first-limiting amino acid in many of the additives commonly included in swine and poultry is not only justified on the basis of least -cost formulation ,but also enables the nutritionist to balance the diet to meet the animals requirement most closely ,improving the meat quality and promoting the growth of animals, it is widely used in feed additive industry.

AMINO ACIDS (Threonine)



L-Threonine is the necessary complemented of L-Lysine for which it optimizes the use by animals for body protein deposition and weight gain. Moreover, L-Threonine plays an important role in processes of maintenance and, more particularly of digestion. In practice, L-Threonine is the second limiting amino acid in feed for pigs and the third limiting amino acid in feed for poultry. L-Threonine is a high quality product specifically designed for the feed industry.

  • Keep the balance of amino acid in the forage and stimulate the growth of the animals;
  • Improve the meat quality;
  • Increases the nutritive value of forage raw materials which have low amino acid digestibility;
  • Apply to the production low-protein forage;
  • Cut down the cost of raw materials for forage;
  • Decrease the nitrogen content in the excrement and urine of animals so that the release of ammonia is slowed and the ammonia concentration is kept low in animal shed; 

L-Threonine is manufactured by fermentation from carbohydrate sources. SWISS uses vegetables high in carbohydrate as the raw material for the fermentation process. L-Threonine is manufactured under strict GMP conditions. No materials of animal origin are used in the production of L-Threonine.


AMINO ACIDS (Tryptophan)


L-Tryptophan is one of essential amino acids and the forth limiting amino acid in animals diets,which means it could not be synthesized by the body,in addition,dietary supply  through feed materials is usually insufficient.  

The deficiency of L-Tryptophan was generally characterized as decreased feed intake and efficiency,and slow growth rate.Considering L-Tryptophan playing a key role in growth performance and feed efficiency, it is recommended to add L-Tryptophan in diet to achieve the optimal amino acid balance and fulfill the digestible tryptophan requirement of animals, especially piglets, sows and poultry etc.


  • Supplement L-Tryptophan in feed can offer following benefits for the industry, which have been proven by abundant trials and research.
  • Increase the feed intake.
  • Optimize the amino acid profile in feed, particularly essential amino acid profile
  • Reduce crude protein level in diets without impact on animal growth performance, particularly low protein diets for post-weaned piglets.
  • Improve the growth rate,weight gain and feed efficiency.
  • Enhance the overall growth, even under stress conditions for immune system,such as depressed, vaccination and deteriorated hygiene conditions.
  • Save the entire cost of feed.
