effect of hibiscus sabdariffa on performance of broilers fed aflatoxin contaminated diet

effect of adding hibiscus sabdariffa (hs) in diet on performance and immune response of broilers was examined during aflatoxicosis using a total of 192 day-old ross 308 male chicks in a completely randomized design with four treatments, four replicates and 12 chicks per each replicate. treatments were include: 1. negative control (without additives), 2. positive control (2.5 mg aflatoxin b1/kg), 3. diet containing hibiscus sabdariffa(10 g hs/kg) and 4. diet contaminated with aflatoxin and containing hibiscus sabdariffa (2.5 mg afb1/kg + 10 g hs/kg). effect of treatments on feed intake was not significant. weight gain of chicks in positive control treatment was lower than those birds in other treatments (p
