performance, immune responses of heat stressed broiler chicks in response to dietary levels of propolis
نویسندگان
چکیده
this experiment was performed to investigate the effects of propolis and chromium picolinate on performance and immune response of broiler chicken under heat stress conditions. treatments included different levels of propolis (500, 1000, and 1500 mg/kg) and chromium picolinate (1500 µg/ kg) along with a control group. a completely randomized design was taken into account with 4 replicates of 10 ross (308) male broiler chicks per treatment under heat stress conditions (34 ±2°c, 5 hours/day). the chicks received treatments from 1 to 42 days. birds fed 1500 mg/kg propolis had significantly higher feed intakes (p
