Abstract
Glucostatic regulation theory has not yet been applied to the feeding behavior in chickens, though recently glucose infusion into the lateral ventricle had been reported to inhibit eating. Then, at first in the present experiments, 0.5mg/l ml/hr of glucose were infused chronically into the third ventricle near the hypothalamus, with a mini osmotic pump implanted peripherally. As the results, daily feed consumption was decreased during 7 days. Nextly, 2μl of 500mg/dl of glucose were infused into the inferior hypothalamic nucleus, and their316 Japan. Poultry Sci., 21 (6), 1984feeding behavior was depleted during one hour. From these results, it is supposed that there exists a glucoreceptor in the hypothalamic satiety center also in chickens, and the glucoreceptor receive a sign of hyperglycemia to control feeding behavior.
