Uses: As amino acid widely added in the forage for newborn pig, covering pig, poultry, shrimp, eel and so on.
--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.
