THE EFFECTS OF CORTICOSTERONE AND CATECHOLAMINE INFUSION ON PLASMA-GLUCOSE LEVELS IN CHICKEN (GALLUS-DOMESTICUS) AND TURKEY (MELEAGRIS-GALLAPAVO)

1. Continuous 5hr infusion of low levels of corticosterone, epinephrine, isoproterenol or phenylephrine plus a high dose bolus injection at 3 hr had different effects on the plasma glucose levels of chickens and turkeys. 2. Corticosterone had no effect on plasma glucose in turkeys, but increased glucose after the bolus and at 270 and 300 min for chickens. 3. Epinephrine increased plasma glucose in turkeys, but only caused a transient elevation after the bolus in chickens. 4. Isoproterenol increased plasma glucose in turkeys, but had no effect in chickens. 5. Phenylephrine increased plasma glucose after the bolus in turkeys but had no effect in chickens.
