Stimulation of feeding in the satiated pig by intracerebroventricular injection of neuropeptide Y.
Operant feeding and drinking were studied in satiated pigs following injection of 0 (saline vehicle control), 25, 50 or 100 micrograms neuropeptide Y into the lateral cerebral ventricles. Neuropeptide Y stimulated feeding in a dose related manner without any apparent aversive effects. No facilitation of drinking was observed.
