Abstract

A laboratory model, set to simulate the in vivo conditions of the porcine gastrointestinal tract, was used to study the small intestinal absorption of several mycotoxins and the effectiveness of Standard Q/FIS (a carbon/aluminosilicate-based product) in reducing mycotoxin absorption when added to multitoxin-contaminated diets. Mycotoxins were quickly absorbed in the proximal part of the small intestine at levels of 105 and 89% for fumonisins B1 and B2, respectively, 87% for ochratoxin A, 74% for deoxynivalenol, 44% for aflatoxin B1, and 25% for zearalenone. Addition of Standard Q/FIS to the diet (up to 2%, w/w) significantly reduced mycotoxin absorption, in a dose-dependent manner, up to 88% for aflatoxin B 1, 44% for zearalenone, and 29% for the fumonisins and ochratoxin. Standard Q/FIS was ineffective in reducing deoxynivalenol uptake. These findings suggest that Standard Q/FIS can be used as a multitoxin adsorbent material to prevent the individual and combined adverse effects of mycotoxins in animals. © 2007 American Chemical Society.
