Threonine Description

L-threonine is an essential amino acid, and threonine is mainly used in medicine, chemical reagents, food fortifiers, feed additives and the like. In particular, the use of feed additives has increased rapidly. It is often added to feed for juvenile piglets and poultry. It is the second limiting amino acid for pig feed and the third limiting amino acid for poultry feed. Adding L-threonine to the compound feed has the following characteristics: 1 can adjust the amino acid balance of the feed and promote the growth of the livestock; 2 can improve the meat quality; 3 can improve the nutritional value of the feed with low amino acid digestibility; 4 can be reduced The cost of feed ingredients; therefore, it has been widely used in the feed industry in EU countries (mainly Germany, Belgium, Denmark, etc.) and the Americas.

Threonine Function

In the catabolism of the body, threonine is the only one that does not undergo deamination and transamination, but is directly converted to other substances by threonine dehydratase, threonine dehydrogenase and threonine aldolase. The amino acid, such as threonine, can be converted to butyryl-CoA, succinyl-CoA, serine, glycine, and the like. In addition, excessive threonine can increase the activity of lysine-α-ketogluconate reductase. Adding proper amount of threonine in the diet can eliminate the body weight loss caused by lysine excess, protein in liver and muscle tissue. /Deoxyribonucleic acid (DNA), ribonucleic acid (RNA) / DNA ratio is reduced. The addition of threonine also reduces growth inhibition caused by excess tryptophan or methionine. It has been reported that the absorption of threonine in chickens is mostly in the duodenum, and the threonine absorbed by the gills and glands is rapidly converted into liver proteins and deposited in the body.

Threonine Application
1. threonine Used to balance amino acids and promote protein synthesis and deposition
It can eliminate the weight loss caused by the excess of lysine and reduce the growth inhibition caused by the excess of tryptophan or methionine; it can be converted into other amino acids after absorption into the body, especially when the amino acid imbalance of feed is more important.
2, increase feed intake
Threonine has a certain regulation effect on feed intake, feed intake and daily gain increase with the increase of threonine level; when the maximum requirement is exceeded, with the increase of threonine level, feed intake The decrease in the amount and daily gain, that is, too much or too little threonine will reduce feed intake and daily weight gain.
3. Immunity
Threonine deficiency inhibits the production of immunoglobulins and TB lymphocytes, which in turn affects immune function. Threonine is the main limiting amino acid in avian immunoglobulin molecules. Adding threonine can improve chicks against Newcastle disease virus. Antibody titer.
4, regulate fat metabolism
The addition of threonine to animal diets has a significant effect on body fat metabolism, which promotes phosphorus synthesis and fatty acid oxidation.
5, reduce the diarrhea rate of piglets
The experiment proves that threonine is the main component of small intestinal mucin protein, which is essential in the synthesis of glycoprotein on the surface of pig small intestine, and plays an important role in maintaining the intestinal health and intestinal mucosal function of pigs, especially suckling pigs. Reducing dietary crude protein content by adding synthetic amino acids to low protein diets is both economical and has no adverse effects on animal performance. It is especially important for early weaned piglets. Since the digestive system of the piglets is not yet fully developed, the nutrient squat is easily induced when the protein content in the diet is high. The low protein diet supplemented with synthetic amino acids can reduce the incidence of diarrhea in piglets.
