Threonine is an amino acid that animals cannot synthesize themselves, but it is highly needed. It can be used to accurately balance the amino acid composition of feed, meet the needs of animal growth and maintenance, increase weight gain and lean meat percentage, and reduce feed to meat ratio; It can improve the nutritional value of feed materials with low amino acid digestibility and enhance the production performance of low-energy feed; Can reduce the level of crude protein in feed, improve feed nitrogen utilization efficiency, and reduce feed costs; Can be used for raising and breeding pigs, chickens, ducks, and high-end aquatic products. L-threonine is a feed additive produced by liquid deep fermentation and refining of raw materials such as corn starch using bioengineering principles. Adjustable amino acid balance in feed can promote growth, improve meat quality, enhance the nutritional value of feed materials with low amino acid digestibility, and produce low protein feed, which helps to save protein resources, reduce feed material costs, lower nitrogen content in animal manure and urine, and reduce ammonia concentration and release rate in livestock and poultry houses. Widely used for adding piglet feed, pig feed, broiler feed, shrimp feed, and eel feed.
