Product Description:
Threonine was isolated and identified by W. C. ose in 1935 from the hydrolysate of fibrin. It has been proved to be the last essential amino acid to be discovered. It is the second or third limiting amino acid in livestock and poultry, and it has extremely important physiological functions 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 is an amino acid that cannot 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.

 

Application: 

L-threonine is an essential amino acid, widely used in medicine, food, animal feed and so on. In recent years, the demand for L-threonine in domestic and foreign markets has increased year by year.
