This study was conducted to investigate the protective role of both commercial products of probiotics + Vitamin E and selenium against the effects of aflatoxin in the broiler. A total of 200 chicks were divided into four groups (50 chicks each) as following: The T1 treated with probiotic with aflatoxin: T2 treated with vitamin E and selenium with aflatoxin: T3 non-treated group (fed on diet with aflatoxin): T4 control negative (diet without aflatoxin). The results revealed that the differences in the body weight of the T1 at 25 days (994 gm) and 35 day (1860 gm) were not significant as compared with corresponding estimations of 1011 and 1876 gm in the T4. Concerning the leukocyte count and H/L ratio results showed no significant difference between T2 (0.42) and T4 (0.41) compared with T1 (0.84) and T3 (1.29). The histopathological examination revealed that probiotics have the best impact compared with vitamin E+selenium. In conclusion: this study confirmed the protective role of probiotic on body weight and histopathological changes, while vitamin E and selenium had a protective role on leukocyte count.
