Application

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