The aim of this study was to evaluate the effects of Pillaring bentonite nanostructure on growth performance, carcass components and blood parameters of broilers challenged by aflatoxin (AF). A total of 128 day-old Ross 308 broiler chicks in a completely randomized design were randomly allotted to 4 treatments, 4 replicates and 8 birds in each. The birds were reared for 35 days. Experimental groups consisted of: negative control (C), positive control (basal diet with aflatoxin) (AF) and two level 0.25 and 0.75 % of Pillared bentonite added to basal diet with aflatoxin B1 (positive control). The Pillaring process increased the concentration FeO (1.99 to 8.42%) and decreased concentration Na2O (2.43 to 0.43 %) in Pillared bentonite as compared to sodium bentonite. The aflatoxin increased feed conversion ratio and enzyme activity ALP and ALT as compared to control diet. Supplementation of 0.25% Pillared bentonite to the infected diet of broilers increased the feed intake and body weight and decreased the concentration of ALT. Addition 0.75% Pillared bentonite increased the concentration of ALT and ALP as compare to positive control. Therefore, the supplementation of Pillared bentonite nanostructure to broiler diets infected with aflatoxin improved the performance and reduced the liver enzyme activity. The results of present research showed that Aflatoxin may had no effect on body weight and feed intake of broilers and the levels of 0.25 Pillared bentonite nanostructure has the best efficient on performance of broiler fed diets contained aflatoxin.
