Angiotensin-induced dipsogenesis in domestic fowl (Gallus gallus)

Both systemic (100 mug, 200 mug, and 400 mug im) and intracranial (75 ng, 150 ng, and 300 ng) injections of Val5-angiotensin II-amide produce copious and dose-related drinking in White Leghorn chickens in normal water balance. Angiotensin-induced drinking has been reported in several mammalian species and in Barbary doves and white-crowned sparrows. The findings reported here extend the species generality of angiotensin-induced thirst and are evaluated in light of current biochemical and pharmacological analyses of the renin-angiotensin system in chickens.
