Aflatoxin adsorbent capacity of two Mexican aluminosilicates in experimentally contaminated chick diets

Abstract
To study the aflatoxin‐adsorbent capacity of two Mexican aluminosilicates (ALS) identified as Atapulgita (AT) and Füller earth (FE), these ALS were compared with a commercial aluminosilicate, Novasil (NV), at two concentrations (005 and 1.0%) added to chick diets with 55% of experimentally contaminated corn (200 μg/kg). Eight treatments were studied with two replicates for treatment and four chicks per cage. Results (weight gain, feed efficiency, gross and microscopic pathology) at 3 weeks showed that both Mexican ALS were as efficient as the commercial material in protecting chicks against the aflatoxin toxicity.
