3,Use
Feed-grade L-threonine is an important nutrient supplement can strengthen cereals , pastries, dairy products, and tryptophan as to restore the body fatigue , and promote the growth and development results . Medicine , due to feed-grade L - threonine structure containing hydroxyl groups on the human skin has the role of water-holding combination with the oligosaccharide chain , play an important role to protect the cell membrane phospholipid synthesis and fatty acid oxidation in the body can promote . Its preparations to promote human development to lipotropic pharmaceutical performance, is a component of the composite amino acid infusion . At the same time , feed-grade L-threonine is to create a class of high efficiency and low allergy antibiotic single - Amide streptozotocin raw materials .
With the improvement of people's living standards and the development of aquaculture , feed-grade L-threonine as a feed amino acids, widely used to add the piglet feed , pig feed, chicken feed , shrimp feed and eel feed . Has the following characteristics:
——Adjustable feed amino acid balance, and promote growth;
——Can improve the meat;
——Can improve the nutritional value of the low amino acid digestion of feed raw materials;
——To produce low - protein feed, and help to save protein resources;
——Can reduce the cost of feed ingredients;
——Can reduce the nitrogen content in livestock manure and urine , the ammonia concentration in the animal building and release rate.
