title: Feeding responses to infusions of glucose solutions into the duodenum of cockerels and the influences of pre-fasting or vagotomy.
abstract: 1. 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).
