Like tryptophan, Threonine rejuvenates human bodies and promotes the growth of infants. When applied in pharmaceutical field, threonine can moisten human skins due to the hydroxy in its structure. Combined with oligose, it protects human cell membranes, and accelerates the synthesis of phosphatide and the oxidation of fatty acid. With a medicinal effect of preventing fatty liver, threonine preparation works as a component of compound amino acid injection, Meanwhile, threonine can be used for the production of monobactams, one of high-effect and low-allergy antibiotics.

  • Keep the balance of amino acids in the forage and stimulate the growth of the animals;

  • Improve the meat quality;

  • Increase the nutritive value of forage raw materials which have low amino acid digestibility;

  • Apply to the production low-protein forage;

  • Cut down the cost of raw materials for forage;

Decrease the nitrogen content in the excrement and urine of animals so that the release of ammonia is slowed and the ammonia concentration is kept low in animal shed.
