Threonine has a very critical physiological function in animals’ bodies, these functions include promoting growth, improving immune functions, balancing amino acids in daily ration and making the amino acid proportion close to ideal protein so that it can reduce the beasts and birds’ demand for protein level in fodder. Lack of threonine may cause a reduction of food consumption, growth suffocation, reducing of feed utilization efficiency and restraining of immune functions. Since in recent years the synthetics of lysine and methionine has widely been applied in the fodder, threonine has gradually become a restrictive factor for influencing the animal production performance. Further research has shown threonine contributes to effective guiding of beasts and birds production.
With bioengineering theory, L-Threonine is a kind of feed supplement produced through submerged fermentation and refining of corn starch and other materials. Threonine (L-Threonine) is a kind of very critical amino acid which can’t be formed in the body of animals. It can adjust amino acid balance in fodder, promote growth, and improve nutritive value of feedstuff with low amino acid. It can also be used to produce low protein feed, promote growth, improve meat quality, reduce feed material cost, and reduce the nitrogen content of excrements and urine of livestock, ammonia concentration and release rate in animal building. It’s widely added in piglet feed, breeding swine feed, broiler feed, prawn feed and sea eel feed.
