Abstract: Amino acids are one of the most important dietary components in piglets, but the traditional classification of amino acids is defective. Functional amino acids are a redefinition of traditional amino acids and play an important role in animal immune function.This paper summerizes the metabolic effects of functional amino acids such as arginine, glutamate, glutamine, branched-chain amino acids, tryptophan, glycine, cysteine and proline in the intestinal tract of weaned piglets and their effects on intestinal health. The mechanism of functional amino acids to repair intestinal damage is also elucidated. In order to provide a basis for functional amino acids application in intestinal injury repair of weaned piglets.

Key words: functional amino acids, weaned piglets, intestine, damage repair, mechanism
