摘　　要：蛋白质在反刍动物体内的降解产物之一是小肽,小肽构成进入小肠的可吸收可溶性氮的主要成分。与氨基酸相比,小肽具有自身的可吸收优势,而小肠是乳蛋白前体物合成的部位之一。本文就瘤胃、瓣胃对小肽的吸收能力、小肠内小肽的来源、小肽的吸收机制及其影响因素进行了综述。Small peptide is one of the degradation products of the protein in ruminant, small peptides constitute the main component of the absorbable soluble nitrogen into the small intestine. Compared with the amino acid, small peptides have their own advantages of being absorbed, while the small intestine is one of the sites where milk protein precursors synthesized. In this paper, the absorptive capacity of the small peptides of rumen and omasum, the source of small peptides in the small intestine, small peptide absorption mechanism and its influencing factors were reviewed.
