Abstract

Threonine (Thr), is considered as the dietary second or third limited amino acid for pigs. Supplementing optimal levels of Thr in the diets could effectively improve dietary amino acid balance, promote the synthesis of body proteins, regulate the lipid metabolism, improve the immune function, and enhance the growth performance in piglets. Moreover, dietary Thr supplementation could enhance the intestinal barrier function by affecting the number of goblet cells and the synthesis of intestinal mucins, and improve the intestinal morphology and structure, as well as modulate the composition of gut microbiota, in order to improve the intestinal health of piglets. This paper summarizes the physicochemical properties and metabolic pathways of Thr, as well as the application of Thr in piglet production and the Thr requirement of piglets and its influencing factors, thus providing guidance for the precise use of Thr in piglets.
