About product

L-Tryptophan 98.5% feed - a protein amino acid from the group of exogenous (essential) for the functioning and increase in body weight of farm animals. L-Tryptophan is involved in the biochemical processes of the synthesis of serotonin, melatonin, niacin and tryptamine. This amino acid is a very important feed additive used in the nutrition of pigs and poultry. Tryptophan is essential for the functioning of the body because it is not synthesized by the body and must be supplied in the feed.


  • improves the growth of meat mass
  • improves feed utilization
  • participates in calcium metabolism
  • stimulates bone growth, development of the skeletal system
  • stimulates cell division, nucleotide synthesis
  • initiates the production of proteins, hormones and antibodies
  • strengthens the body's immune system
  • regulates appetite processes


  • addition to feed premixes for pigs and poultry
  • component of a balanced ration for pigs and poultry
  • ingredient in sedatives for dogs
L-Tryptophan as an essential amino acid participates in the transformation of many important compounds such as serotonin, melatonin, niacin and tryptamine. Tryptophan is a precursor of the "happiness hormone" serotonin, which is responsible for a good mood, proper functioning of the digestive and nervous systems. L-Tryptophan also participates in the production of melatonin, which is responsible for proper sleep. Therefore, the deficiency of L-Tryptophan in animal feed significantly affects the well-being of animals and thus the increase in meat mass. L-Tryptophan deficiencies are also manifested by a decrease in energy, deterioration of well-being and intensification of sleep problems. Forages with the appropriate content of tryptophan are better absorbed by piglets and sows during the feeding period. An important challenge in feeding lactating sows is to increase feed intake, which is why the right mix composition is crucial. L-Tryptophan plays a key role in appetite regulation processes. Supplementing the feed with L-Tryptophan improves its amino acid profile and significantly increases the growth of meat mass in piglets. Tryptophan as an exogenous amino acid also affects the proper functioning of the immune system. Its increased demand depends on the living conditions of animals. Greater use and demand for tryptophan was found in animals reared in worse living conditions.
