Food and water intake response of turkeys to intracerebroventricular injections of angiotensin II.

The effects of intracerebroventricular (ICV) injections of angiotensin II on food and water intake were studied in adult Medium White turkey hens. Food intake was not significantly affected by ICV injections of angiotensin II. The ICV injection of 50, 100, and 200 ng of angiotensin II significantly increased water intake in a dose-dependent manner. The dipsogenic effect of angiotensin II was significantly attenuated by Saralasin, an angiotensin blocker. These results suggest that angiotensin II functions in neural pathways within the central nervous system to control water intake, but not food intake, in turkeys.
