Effect of Fasting and High-Fat Diet Feeding on Plasma and Pancreatic Insulin Contents in Young Chick Given an Oral Glucose Load[*]

Abstract

Experiments were conducted to determine the effect of fasting or high-fat diet feeding on the pancreatic insulin content and on the plasma insulin response of the chicks to an oral glucose load. Thirty-hour-old chicks not fed and one-week-old high-fat diet fed chicks showed a significant response. One-week-old mash-fed 30 hr fasted chicks showed a greater rise in insulin level in response to glycemic stimulus. On the other hand one-week-old mash-fed chicks showed the poorest response.

The pancreatic insulin content (units/100 gm body weight) of the 30 hr old chicks was significantly lower than those of other three groups.

The results suggest that chick when fasted or fed a highfat diet, in contrast to rat, maintains its responsiveness to a glycemic stimulus.
