Main use

1. Mainly used as a nutritional supplement. It is easy to heat with glucose to produce coke and chocolate flavor, which has the effect of enhancing flavor. It can also be used for biochemical research.

2. Threonine is an essential amino acid used as a dietary nutrient enhancer. Threonine is often added to the feed of juvenile piglets and poultry, and is the second restricted amino acid in pig feed and the third restricted amino acid in poultry feed. Added to wheat, barley and other grain-based feed.

3. Nutritional additives, also used in the preparation of amino acid infusion and comprehensive amino acid preparations.

4. Threonine (L-threonine) was isolated and identified from the hydrolyzed products of fibrin by W.C. ose in 1935, and has been proved to be the later found essential amino acid, it is the second or third limiting amino acid of livestock and poultry, and it has extremely important physiological effects in animals. Such as promoting growth, improving immune function, etc.; Balance the amino acids of the diet, so that the amino acid ratio is closer to the ideal protein, so as to reduce the protein content of livestock and poultry feed requirements. The deficiency of threonine can lead to the decrease of feed intake, growth retardation, feed utilization and immunosuppression in animals. In recent years, the synthesis of lysine and methionine has been widely used in feed, and threonine has gradually become a limiting factor affecting animal production performance. Further research on threonine is helpful to effectively guide livestock and poultry production.

Threonine (L-threonine) is an amino acid that can not be synthesized by animals, but is very needed. It can be used to accurately balance the amino acid composition of feed, meet the needs of animal growth and maintenance, improve weight gain and lean meat rate, and reduce feed to meat ratio. It can improve the nutritional value of feed materials with low amino acid digestibility and improve the production performance of low energy feed. It can reduce feed crude protein level, improve feed nitrogen utilization and reduce feed cost. It can be used for raising and breeding pigs, chickens, ducks and high-grade aquatic products. L-threonine is a feed additive produced by deep liquid fermentation and refinement of raw materials such as corn starch based on the principle of bioengineering. It can adjust the amino acid balance in feed, promote growth, improve meat quality, improve the nutritional value of feed raw materials with low amino acid digestibility, produce low protein feed, help save protein resources, reduce the cost of feed raw materials, reduce the nitrogen content in manure and urine of livestock and poultry, ammonia concentration and release speed in livestock and poultry houses. It is widely used to add piglet feed, breeding pig feed, broiler feed, shrimp feed and eel feed. [1]

6. Threonine (L-threonine) in the catabolism in the body, is not through deamination and transamination, but directly through threonine dehydrase, threonine dehydrogenase and threonine aldolase catalytic conversion to other substances of amino acids, such as threonine can be converted into butyryl Coenzyme A, succinyl Coenzyme A, serine, glycine, etc. In addition, excessive threonine can improve the activity of lysine-α-ketogluconate reductase, and adding appropriate threonine to the diet can eliminate the decrease in body weight caused by excessive lysine, and reduce the protein /DNA and RNA /DNA ratios in liver and muscle tissue. The addition of threonine can also reduce the growth inhibition caused by excessive tryptophan or methionine. It has been reported that most of the absorption of threonine in chickens is in the duodenum, and the absorbed threonine is rapidly converted into liver protein and deposited in the body.
