摘要
反刍动物的胃是复胃,与单胃动物的胃不同。反刍动物主要以瘤胃中发酵产生的短链脂肪酸(SCFA)作为机体的能量物质,而绝大部分的SCFA又通过瘤胃上皮直接吸收,为宿主供能。因此,深入了解瘤胃上皮结构特点有助于对其吸收功能进行深入的研究。笔者主要对瘤胃上皮的解剖学特点、细胞学特点及超微结构进行了综述。
The ruminant stomach is complex and different from that of monogastric animals. Short chain fatty acids (SCFA) produced by micro- - bial fermentation in the rumen of ruminants, are used as the major energy source of the body. And most of SCFA are directly absorbed through the rumen epithelium for supplying energy to the host. Therefore, further understanding the structural features of rumen epithelium is helpful for us to study in depth its absorption. The anatomical and cytological features and ultrastructure of the rumen epithelium in ruminants are reviewed in this paper.
