Function of L-Threonine:
As amino acid for forge,threonine is widely added in the forage for newborn pig,covering pig,poultry,
shrimp,eel and so. It can:
--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.
