feed additive Valine price

L-Valine is an essential and indispensable nutrient for pigs and poultry like lysine, theonine, methionine and tryptophan. In practical European formulas, it is usually considered as the fifth limiting amino acid. As it cannot be sythesized in the body, it needs supplementation from the diets.     Description: L-valine is the white crystals or crystalline powder, tasteless, no peculiar smell. Freely soluble in formic acid, soluble in water, practically insoluble in ethanol and ether.     Application: L-Valine is a branched chain amino acid along with leucine and isoleucine, involved in many important biological functions. Besides, valine can improve the feed conversation rate and amino acid efficacy.     Storage:  sealed and store away from direct sun light.Store in a well-closed container away from moisture   Specifications:
