Name: L-Threonine FEED GRADE CAS NO: 72-19-5 Molecular weight: 119.12 Specification Appearance: White or light-brown crystal or powder Loss on drying: 1.0% Max Residues on ignition: 0.5% Max Assay: 98.5% Min Specific rotation: -26.7 -29.6 Heavy metals: 10PPM Max Arsenic: 2PPM Max PH: 5.0-6.5 Packing 25kg in a compound bag. One 20'FCL can load 20 tons L-Threonine(Feed Grade). Usage: 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.
