Abstract
- The duodenum of cockerels was chronically catheterised, to study the effects of 3 h infusions of glucose solutions on voluntary food intake. 2. Compared to water, solutions containing 30, 60 and 90 g glucose/l infused at 1 ml/min induced significant, dose-related depressions in intake after the first 30 min of infusion. 3. Fasting the birds for 3 h before the start of infusion resulted in higher intakes during the period of infusion than in unfasted birds. 4. Vagotomy at the level of the proventriculus prevented the inhibitory effects of glucose infusion into the duodenum, except at the highest concentration (120 g/l).
摘要
- 对公鸡的十二指肠进行长期插管，以研究3小时输注葡萄糖溶液对自愿采食量的影响。2. 与水相比，以1毫升/分钟的速度输注含30、60和90克葡萄糖/升的溶液，在输注的前30分钟后，采食量出现显著的、与剂量相关的下降。3. 在开始输注前让鸡禁食3小时，导致输注期间的采食量高于未禁食的鸡。4. 在腺胃水平进行迷走神经切断术可防止向十二指肠输注葡萄糖的抑制作用，但最高浓度（120克/升）除外。
