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. Valine is a branched chain amino acid along with leucine and isoleucine, involved in many important biological functions. It can help to improve the milk yield for lactating sow and enhance animal's immune.Besides, Valine can improve the feed conversation rate and amino acid efficacy.
2.For Food Grade Valine:
L- valine is a branched chain amino acid, along with leucine and isoleucine, which are essential to repaire tissue, regular blood glucose and provide energy for human body, especially for vigorous exercise. Therefore, it can be used for sports drink. Besides, Valine can also be used as a food additive in bakery to improve flavor of food.
3.For Medicine Grade Valine:
As one of amino acid infusions, valine can be used to treat some liver disease. Besides, valine is one of the precusor substances for synthesis of new drugs.
