摘　　要：瘤胃发育是犊牛生长发育的重要指标。论述瘤胃的组织形态学发育,通过对瘤胃上皮乳头长度、宽度、颜色、密度,瘤胃壁及其肌肉层厚度等相关性状的描述,探讨了犊牛日龄、饲料组成及其形态、挥发性脂肪酸,瘤胃pH值和瘤胃微生物等各种因素对犊牛瘤胃发育的影响。The development of rumen is crucial for the development of calves. The present review summarizes the development of rumen in the aspects of the length, width, color of papillae, the number of papillae in one square centimeter, and the thickness of rumen and muscle, and discusses the mode of actions from the following points of view： the age of calves, the composition and shape of ration, VFA, pH-value and microbe in rumen.
