The purpose of this experiment was to investigate the effects of ascorbic acid on physiopathology of broilers under chronic heat stress. Broilers at 28 days of age were maintained at 26-28 degrees C and subjected to a daily 5 h episode of heat stress at 33+or-1 degrees C environmental temperature and supplemented with four levels of ascorbic acid: 0 (control group), 200, 400 and 800 mg/kg in their diets for 21 days.
