中文摘要：

小肽是动物降解蛋白质过程中的中间产物，是由2个或2个以上的氨基酸以肽键相连的化合物，其吸收在总饲粮蛋白质的吸收中有重要作用。本文综述肠道对小肽的吸收利用及其调控机制，肠道小肽感应与胃肠激素分泌和摄食调控，肠道小肽利用对肠道健康的调控，以及小肽在动物营养中的应用。

英文摘要：

Small peptides are the degradation products from protein, consisting of 2 or more amino acids joined by peptide bond（ s） . Peptides uptake play a more important part in dietary protein absorption. This review sum-marized the mechanisms of peptide absorption and utilization in the intestine, peptide sensing involved in gas-trointestinal hormone secretion and feed intake regulation, the regulation of peptide utilization on intestinal health, as well as the application of small peptides in animal nutrition.
