In sheep, provided with re-entrant cannulas in the caudal duodenum and with an infusion tube into the abomasal fundus, emptying of the liquid phase of the abomasal contents was studied with [57Co]EDTA. Radioactivity was measured continuously with Geiger-Müller counters placed along the re-entrant cannulas. It appeared that first-order kinetics could be applied to the elimination of [57Co]EDTA from the abomasum. Mean retention time of this label in the abomasum was 40-50 min. Infusion of a suspension of soya-bean protein in saline (9 g sodium chloride/l) caused an initially decreased rate of abomasal emptying, but after 48 h an adaptation had occurred to the original rate of emptying producing an increased volume of abomasal contents and increased flow-rate of digesta into the duodenum.
在绵羊的尾段十二指肠植入再入式套管，并在皱胃底部插入一根输液管，用[57钴]乙二胺四乙酸研究皱胃内容物液相的排空情况。沿着再入式套管放置盖革-米勒计数器连续测量放射性。结果表明，一级动力学可用于描述[57钴]乙二胺四乙酸从皱胃的消除过程。该标记物在皱胃中的平均保留时间为40 - 50分钟。向盐水中注入大豆蛋白悬浮液（9克氯化钠/升），最初会导致皱胃排空速率下降，但48小时后会适应原来的排空速率，使皱胃内容物体积增加，进入十二指肠的食糜流速加快。
