Involvement of Central β-Adrenergic Circuitry in Food and Water Intake in Chickens
We examined the effects of intracerebroventricular (i.c.v.) microinjections of α, β-adrenergic agonist, isoproterenol (ISOP), and of a β₁,₂-adrenoceptor blocker, propranolol (PROP), on food and water intake in broiler cockerels deprived of food and water for 3 h. We found that ISOP, at a 200 n...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | We examined the effects of intracerebroventricular (i.c.v.) microinjections of α, β-adrenergic
agonist, isoproterenol (ISOP), and of a β₁,₂-adrenoceptor blocker, propranolol (PROP), on
food and water intake in broiler cockerels deprived of food and water for 3 h. We found that
ISOP, at a 200 nM concentration and not smaller, significantly (P ≤ 0.05) increased food
intake but not water intake. PROP microinjected in different doses (20-80 mM) significantly
(P ≤ 0.05) decreased food intake. These observation suggest a direct orexigenic role for the
β₁ - and β-adrenergic systems in the regulation of food intake in chickens. The significant
(P ≤ 0.05) effect of i.c.v. injections of PROP (transient increase in water intake) implies a role
of the adrenergic system, possibly via α-adrenoceptors, in the regulation of water intake in
broilers, which is food intake-independent. |
