As the body temperature of birds rise, growth and production parameters tend to decline. In order to address the problem of heat stress, an experiment was conducted to investigate the effect of different herbal antistressor products on the performance and carcass traits of broilers. For this, 180 day-old commercial straight run broiler chicks were randomly divided into six treatment groups with six replicates of five birds each. The experimental design consisted of; T1 control diet, T2: Stressroak liquid, T3: AV/ESL/16 liquid, T4: Stressroak premix, T5: Geriforte liquid, T6: Stresscheck. The results indicated that Stressroak liquid had significantly (P<0.05) higher body weight gain (2062 g) and better feed efficiency (1.49) compared to other treatments at 42 d of age. However, among other test diets, cumulative body weight gain was comparable with control during 42 days of age. Significantly (P<0.05) higher feed intake was recorded in control group compared to other test groups at 42 d of age. All herbal products did not have significant (P>0.05) effect on various carcass parameters studied, except for abdominal fat percentage and drum stick, which was significantly (P<0.05) lower in all the test diets compared to control. All the test groups had significantly (P<0.05) high spleen and bursa weight when compared to control.
