Reduced food intake following cerebral intraventricular infusion of glucose in Gallus domesticus.
Unanaesthetized hens and cocks were infused into the cerebral lateral ventricle with 0.2 ml of a 6% glucose solution or equal volumes of isotonic saline following a 20-hr total food deprivation period. A more marked suppression of food intake occurred in the next 1-3 hr after glucose rather than after saline. The results provide new evidence that chickens possess central glucoreceptors involved in the regulation of their feeding behavior.
