The response of the immature fowl to multiple injections of adrenaline.

Chicks were injected, from one to 21 days of age, with either L-adrenaline (500 mug/kg) or the solvent three times a week. Birds treated with adrenaline showed an imparied growth rate. Relative (mg/kg0.75), but not absolute (mg) adrenal weight was significantly increased. No changes in adrenal cholesterol content or concentration were noted.
