A study was carried out to investigate the efficacy of diatomaceous earth (DE), sodium bentonite (SB) and zeolite (Z), alone or in combinations as aflatoxin adsorbents in the diets of broiler chickens containing 300 ppb aflatoxin B1 (AFB1). Day-old broiler chicks (384) were divided into 12 treatment groups (T1, control; T2, T1 + 300 ppb AFB1; T3, T2 + 0.5% DE; T4, T2 + 1% DE; T5, T2 + 0.5% SB; T6, T2 + 1% SB; T7, T2 + 0.5% DE +0.5% SB; T8, T2 + 0.5% Z; T9, T2 + 1% Z; T10, T2 + 0.5% Z + 0.5% DE; T11, T2 + 0.5% Z + 0.5% SB; T12,T2 +[Z+DE+SB (0.33% each)]). Each diet was offered from day-old to 42 days of age to 4 replicated groups of 8 birds each. Feeding diet with 300 ppb of AFB1 in diet caused significant decrease in body weight gain (BWG 1168g) as compared to control (1 429 g). Inclusion of all the binders in aflatoxin contaminated diet, alone or in combinations, improved the overall BWG (1 290 to 1 389 g/bird),
however, significantly lower BWG was recorded in DE groups in comparison to other binders during 0–6 weeks growth period. The BWG did not differ between zeolites and sodium bentonite groups. Feed consumption was not affected during the first week of age but reduced thereafter on diet with 300 ppb level of dietary AFB1. Amongst the binder groups, feed consumption was lowest in DE fed groups. Addition of aflatoxin resulted in poor feed conversion, energy and protein efficiency, which partially improved on inclusions of binders at any levels, alone or in combination. Thus, it may be concluded that addition of 300 ppb AFB1 in the diet of broiler chickens impaired the performance of broiler chickens during 0–6 weeks of age. All the 3 binders at 0.5 or 1% level, alone or in combination, were partially efficacious in ameliorating the adverse effects of aflatoxin. Among the binders tested, diatomaceous earth appeared to be the least efficacious in ameliorating aflatoxicosis in broiler chickens.
