Threonine is produced by W. C． Rose, which was isolated and identified from fibrin hydrolyzate in 1935, has been proved to be the last essential amino acid discovered. It is the second or third limiting amino acid of livestock and poultry, and it has extremely important physiological functions in animals. Such as promoting growth, improving immune function, etc.; balancing dietary amino acids, making the ratio of amino acids closer to ideal protein, thereby reducing the requirements of livestock and poultry for protein content in feed. Lack of threonine can lead to symptoms such as reduced animal feed intake, stunted growth, decreased feed utilization, and suppressed immune function. In recent years, synthetic products of lysine and methionine have been widely used in feed, and threonine has gradually become a limiting factor affecting animal production performance. Further research on threonine will help effectively guide livestock and poultry production. Threonine is an amino acid that cannot be synthesized by animals, but is very much needed. It can be used to precisely balance the amino acid composition of feed, meet the needs of animal growth and maintenance, increase weight gain and lean meat rate, and reduce feed-to-meat ratio; it can improve amino acid digestibility The nutritional value of low feed raw materials can improve the production performance of low-energy feed; it can reduce the crude protein level of feed, improve the nitrogen utilization rate of feed, and reduce feed cost; it can be used for feeding and breeding of pigs, chickens, ducks and high-grade aquatic products. L-threonine is a feed additive produced by submerged fermentation and refining of cornstarch and other raw materials using the principle of bioengineering. It can adjust the amino acid balance in the feed, promote growth, improve meat quality, improve the nutritional value of feed materials with low amino acid digestibility, and produce low-protein feed, which helps to save protein resources, reduce the cost of feed materials, and reduce livestock manure and urine. Nitrogen content, ammonia concentration and release rate in livestock and poultry houses. It is widely used to add piglet feed, breeding pig feed, broiler chicken feed, prawn feed and eel feed.

1. Threonine is an important nutritional enhancer, which can strengthen grains, cakes, and dairy products. Like tryptophan, it can restore human fatigue and promote growth and development. In medicine, because threonine contains hydroxyl groups in its structure, it has a water-holding effect on human skin, combines with oligosaccharide chains, plays an important role in protecting cell membranes, and can promote phospholipid synthesis and fatty acid oxidation in the body.
2. It is used in biochemical research, and it is used as an amino acid nutritional drug in medicine, mainly for the treatment of anemia.
3. Amino acid drugs. Mainly used for amino acid infusion, comprehensive amino acid preparation, food nutrition enhancer. For example, the lack of threonine can cause loss of appetite, weight loss, fatty liver, testicular atrophy, changes in chromaticity of cells in the anterior pituitary gland, and affect bone development.
4. Nutritional supplements. Cereal protein needs to be supplemented with L-lysine, followed by L-threonine. This is because although the content of L-threonine is relatively high, the combination of threonine and peptide in protein is difficult to be hydrolyzed and difficult to digest and absorb. Also used in the preparation of amino acid infusion and comprehensive amino acid preparations.
5. One of the essential amino acids for the human body, which can be used to improve nutrition and improve physical fitness.
6. Biochemical research. Prepare tissue culture medium.
