be used as feed additives to more effectively bind aflatoxins in feed and prevent toxicity. Preliminary research has shown that other small compounds, such as lysine, aspartame, and phenylalanine, similarly yield surface-modified clays that more readily bind AfB1 than untreated clay. Animal feeding studies would be needed to prove that surface-modified clays, such as SWy-Choline, can reduce the toxicity of ingested aflatoxins as effectively as the adsorption experiments suggest.
