Effect of Protexin to diminish negative consequences of feeding aflatoxin B1 (AFB1) contaminated diet on performance, immune response, meat quality and ileal microbial flora were examined using 320 seven-day-old Japanese quails fed four treatments [control diet (without additives), diet containing 2.5 mg AFB1/kg, diet containing 150 mg Protexin/kg, diet containing 2.5 mg AFB1/kg+150 mg Protexin/kg] with four replicates and 20 birds each in a completely randomized design. Feed intake of birds fed probiotic diet was higher than those birds in control group (P<0.05). Weight gain in birds fed aflatoxin contaminated diet was lower than birds in other treatments (P<0.05). Humoral immunity response in quails related to aflatoxin and probiotic groups was lower and higher than control group, respectively (P<0.05). Skin thickness increase after 48h challenging with dinitrochlorobenzene (DNCB) in birds fed aflatoxin contaminated diet was lower than the other groups (P<0.05). Concentration of malondialdehyde (after freezing meat for 30 days) in the meat of aflatoxin fed birds was higher than the other birds (P<0.05). Population of E. coli and lactic acid bacteria in birds fed protexin or aflatoxin+protexin was lower and higher than the two other groups, respectively (P<0.05). Based on the result of this research, dietary inclusion of protexin probiotics into aflatoxin contaminated diet could improve immunity response and intestinal microbial population in Japanese quails.
