The effect of A and B sequence contractions of the reticulo-rumen on passage rate of digesta was compared in buffaloes and cattle fed low quality rhodes grass. 2. Both species ate the same amount per unit body weight but buffaloes spent 53% more time ruminating than cattle. 3. Buffaloes had fewer A and B sequence contractions each day and the rate of these contractions during eating, ruminating and at rest were slower. 4. A larger pool of fine feed particles in the rumen of buffaloes, generated by extra ruminating activity was associated with the 30% shorter mean residence time of particulate matter in the forestomach compared with cattle. 5. It is concluded that the difference in the number and frequency of contractions between the species was insufficient to affect passage rate of digesta from the stomach.

在以低质量的罗德草为食的水牛和牛中，比较了瘤网胃A和B序列收缩对食糜通过速率的影响。2. 两种动物每单位体重的采食量相同，但水牛反刍的时间比牛多53%。3. 水牛每天的A和B序列收缩次数较少，且在进食、反刍和休息期间这些收缩的速率较慢。4. 与牛相比，水牛瘤胃中因额外反刍活动产生的细饲料颗粒池更大，这与瘤胃中颗粒物的平均停留时间缩短30%有关。5. 得出的结论是，物种间收缩次数和频率的差异不足以影响食糜从胃中的通过速率。
