Feed grade amino acid
L-Lysine
Glycine
L-theronine
DL-methionine
L-Tryptophan
Amino acids are the basic material needed to constitute animal nutrition protein. Animals of the amino acids are L-shaped, so the animal feed L-amino acids can be a good use of some synthetic amino acids are D-type microorganisms also have D-type, for D-amino acids some animals can make good use of some relatively poor utilization. Methionine, cystine, glutamic acid, leucine, phenylalanine, proline and tyrosine either L or D-type, can be a good use of the animal, so now synthetic, added to feed is DL-methionine, and L-lysine.
Amino acids in animal nutrition important role are:
(1) material is a synthetic protein.
(2) to participate in a variety of important physiological activities.
(3) to provide energy.
(4) is necessary for animal production.
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.
