摘　　要：[Objective] The paper was to study the dynamic changes of forage nutrient substance fermentation in rumen, and a set of continuous culture system of artificial rumen was designed. [Method] With in vivo as control, the simulating rumen fer- mentation effect in vitro culture system was evaluated. [Result] The simulation rumen fermentation test needed adaptive phase of 2-3 d, and the fermentation state was relatively stable within 3-9 d, with good effects. The test showed certain regularity variation with index value of rumen in vivo. [Conclusion] The continuous culture sys- tem of artificial rumen could be used as the ideal model to study the rumen fermen- tation in vivo.[目的]研究饲料营养物质在瘤胃内发酵等动态变化规律,设计一套瘤胃体外连续培养系统。[方法]以活体为对照,对体外培养系统模拟瘤胃的发酵效果进行评价。[结果]模拟瘤胃发酵试验需2～3d的适应期,3～9d发酵状态相对稳定,效果较好,并且与活体瘤胃指标值呈一定规律性变化。[结论]瘤胃体外连续培养系统可作为研究活体瘤胃发酵的理想模型。
