Bentonite is a naturally-occurring clay consisting of tri-layered aluminum silicate, and may also contain calcium or sodium. It's main use in the feed industry is as a binding agent in feed pellets. Lately however, bentonite has been used successfully in rations with high mold or toxin levels, as an inhibitor of these substances. Particle size seems to be the biggest difference between brands of bentonite. Most feed-grade bentonite is very coarse. Novasil makes a finely ground version which has been recommended by Randy Shaver. The small particle size allows more surface area to attract and bind the toxins. There are a couple of things to consider when using bentonite. Aluminum can reduce phosphorus absorption so phosphorus levels may need to be increased over present levels. Bentonite can also tie up Zinc and Copper, although ANC levels are already higher. Recommended feeding rates range from 0.1-0.3 lbs./head/day.
