L-neneneba tryptophan/feed additive
L-neneneba tryptophan is the fourth limiting amino acid in animal diets, next only to L-lysine, L-nenenebb threonine and DL methionine. It can improve animal sleep, increase antibodies in fetuses and young, and increase mammalian milk production. In addition, L-neneneba tryptophan can reduce the quantity of high-quality dietary protein, save feed cost, reduce the quantity of dietary protein feed, and save formula space.
