   This study was conducted to determine the effects of Bitter Orange blossom powder (BOBP) on growth performance, carcass characteristics and some blood parameters in broiler chickens under heat stress condition. A total of 200 one day-old male broiler chicks (Ross 308) randomly were divided into five treatment groups in a completely randomized design with four replicates of 10 birds each. The experimental treatments including control (basal diet), the basal diet with Neomycin (0.2% of v diet) and 3 levels of BOBP (0.5, 1 and 2% of diet). Birds submitted to heat stress (32±2ºC from 10.00 AM to 6.00 PM) from 15 to 42 d of age. Blood samples were taken from 8 birds per treatment at the end of experiment. The results showed that, average mortality was significantly lower (P<0.05) in treatments groups (3.75%) than in the control group (22.5%). The diet supplemented with BOBP had no effects on feed intake and weight gain of chicks during different periods (P>0.05). In the grower phase (11-24 d), the lowest fed conversion ratio (FCR) was obtained in 0.5% BOBP, which were significantly different from 2% treatment (P<0.05). Birds receiving diet supplemented with 1% BOBP revealed significantly (P<0.05) lower blood glucose compared to the control group (211 vs 225.8 mg/dl). LDL level was lower (p < 0.05) in 2% BOBP treatment (57.4 mL/dL) compared to 0.5% (69.6 mg/dl). The feeding of BOBP did not induce any significant effect on the whole carcass, breast, drumstick and internal organs weight of broiler chickens (P<0.05). In conclusion, BOBP may be effective in attenuating heat stress effects due to its illustrated antioxidant effects.
