Canine Pancreatic Secretion in Response to Acceptable and Aversive Taste Stimuli ∗

Abstract

Summary

The present study, with conscious dogs, indicates that both pancreatic flow and pancreatic protein output can be affected by the nature of the taste stimuli. Water and a sucrose solution mixed with a basal diet produced a similar and significantly greater stimulation of flow than did citric acid or quinine, which in turn were similar. Although it appeared that protein secretion was more strongly enhanced by sucrose solution than by water and solutions of citric acid and quinine, it was not clearly established that sucrose solution and water were really different. The flow responses for the four taste stimuli were highly correlated with the readiness with which the various food mixtures were accepted by the dogs.
