The function of threonine in feed

Threonine  was discovered in fibrin hydrolyzate in 1935, and it was proved that it was the last essential amino acid discovered. Threonine is mainly used in medicine, chemical reagents, food fortifiers, feed additives, etc. We mainly describe its function as a feed additive. It is often added to the feed of juvenile piglets and poultry. It is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed.

Improve Piglet diarrhea rate

 Threonine is the main component of small intestinal mucus protein, and it is essential for the synthesis of surface glycoproteins in porcine small intestine, and plays an important role in maintaining the intestinal health and intestinal mucosal function of pigs, especially suckling piglets. By adding synthetic amino acids to low-protein diets to increase the crude protein content of the diet, it is economical and has no adverse effects on animal performance. It is especially important for early weaned piglets. Since the digestive system of piglets is not yet fully developed, nutritional diarrhea is easily induced when the protein content in the diet is high. The incidence of diarrhea in piglets can be reduced by using a low-protein diet supplemented with synthetic amino acids.

Improve Feed intake

 Threonine has a certain regulating effect on feed intake, and feed intake and daily gain increase with the increase of threonine level; Feed intake and daily weight gain decrease, that is, too much or too little threonine will affect feed intake and daily weight gain.

 Improve the environment

 Adding threonine to feed can reduce the nitrogen content in manure and urine of livestock and poultry, and the concentration and release rate of ammonia in livestock and poultry houses.

Improve Feed conversion rate

 Adding threonine to laying hen diet can improve egg production and feed conversion rate. When threonine is added to the diet of broilers, the daily weight gain and feed conversion rate can be improved.

Improve Immune function of the body

 In the body's immune system, antibodies and immunoglobulins are proteins, and the lack of threonine will inhibit the production of immunoglobulins and T and B lymphocytes and affect immune function. Threonine is the main limiting amino acid in poultry immunoglobulin molecules, adding threonine can improve the immune function of the body.
