Motility of the digestive tract of 4 sheep was studied with radiotelemetric equipment. After base line records were made, each sheep was overfed with 70 g of grain per kilogram of body weight. The ruminoreticulum did not become static until the ingesta pH was less than 5. The cecum had the same patterns of motility and pH as did the ruminoreticulum, but these returned to normal more quickly in surviving sheep. The motility patterns of the abomasum and the small intestine were more erratic. Results indicated that considerable quantities of grain (substrate for microbial growth) reached the cecum before ruminoreticular motility was inhibited.
用无线电遥测设备研究了4只绵羊消化道的蠕动情况。在记录基线数据后，每只绵羊按每千克体重70克谷物过量投喂。直到食糜pH值低于5时，瘤胃才停止蠕动。盲肠的蠕动模式和pH值与瘤胃相同，但在存活的绵羊中，这些指标恢复正常的速度更快。皱胃和小肠的蠕动模式更不稳定。结果表明，在瘤胃蠕动受到抑制之前，大量谷物（微生物生长的底物）已到达盲肠。
