An esophageal feeder and a rubber nasoesophageal tube were used to administer fluids to calves. Radio-opaque fluids were given and their destination determined by fluoroscopy and radiography. Fluids containing glucose and xylose were also given and plasma glucose and xylose concentrations measured. In at least 93% of calves, the radio-opaque fluids entered the reticulum, indicating that the reticular groove did not close. Oral administration of sodium bicarbonate, copper sulfate and guanidine HCl did not influence groove closure in calves that received fluids through an esophageal feeder. As administration of the fluids continued, overflow to the abomasum occurred after about 400 mL had been given. When 2.0 L of glucose and electrolyte solution was given by esophageal feeder, plasma glucose levels rose significantly (p less than 0.01), showing that absorption had occurred. Plasma xylose levels rose in seven out of eight calves 30 minutes after a second 2.0 L dose (containing xylose) had been administered. Thus, even though esophageal feeders do not cause reticular groove closure, they can be used to administer fluids for enteric absorption, provided large quantities are given.
使用食管喂液器和橡胶鼻食管管给犊牛补液。给予不透X线的液体，并通过荧光镜检查和X线摄影确定其去向。还给予含葡萄糖和木糖的液体，并测量血浆葡萄糖和木糖浓度。至少93%的犊牛中，不透X线的液体进入了网胃，表明网胃沟未关闭。通过食管喂液器给犊牛补液时，口服碳酸氢钠、硫酸铜和盐酸胍不影响网胃沟关闭。随着补液的持续进行，给予约400毫升液体后，会出现液体溢流至皱胃的情况。当通过食管喂液器给予2.0升葡萄糖电解质溶液时，血浆葡萄糖水平显著升高（p<0.01），表明发生了吸收。在给予第二剂2.0升（含木糖）液体30分钟后，八头犊牛中有七头的血浆木糖水平升高。因此，尽管食管喂液器不会导致网胃沟关闭，但只要给予大量液体，它们就可用于给予用于肠道吸收的液体。
