are toxic metabolites produced by fungi in grains. Moderately
contaminated grains that cannot be used as food are often
directed to animal feed. Economically-feasible detoxification
measures for contaminated feeds are needed. The objectives of
this research were to identify effective bentonites as aflatoxin
adsorbents and to evaluate the performance of the clays as
aflatoxin amendments in feeds for broiler chickens. Five
bentonite samples from Gonzales, Texas, USA were collected and
characterized by the published selection criteria for aflatoxin
adsorbents (Dixon et al, 2008). Aflatoxin adsorption capacity,
pH, CEC, organic carbon, particle size distribution, and
mineralogical and structural compositions of the bentonites were
analyzed. Two bentonites were identified as potentially good
aflatoxin adsorbents based on the ana
