APPLICATION:
As one kind of essential amino acid that L-Threonine is, mainly used in the field of Pharmaceuticals, chemical reagent, food additives, feed additives. Especially as feed additives, the demands increase rapidly. It is always be added into feeds of piglets, poultry as second limit amino acids in piglets feeds and third for poultry. Characteristics of compound feed with L-Threonine as follows: 1) Keep the balance of amino acid in feeds to facilitate of growth of piglets and poultry. 2) Improve meat quality. 3) Improve nutritional value of feeds which has low amino acid absorption rate. 4) Reduce cost of feeds. Now, L-Threonine is widely used in Europe (Germany, Belgium, and Denmark) and America countries feed industry.
