Bentonite

Yes. This dual functionality is one of bentonite's key advantages in feed applications. Microngel BN100 provides both effective mycotoxin adsorption in the GI tract and pellet binding strength, making it a cost-effective, multifunctional additive that reduces the need for separate binder and toxin binder additives.

Bentonite adsorbs polar mycotoxins, particularly aflatoxins, through electrostatic attraction to its charged clay surfaces. It shows moderate efficacy against fumonisin and ochratoxin A. For broad-spectrum mycotoxin coverage, bentonite is often combined with HSCAS or zeolite.

No — bentonite improves PDI. PDI measures the percentage of intact pellets after standardised tumbling, and bentonite's binding action increases pellet hardness and cohesion, typically improving PDI by 3–8 percentage points, reducing fines generation during handling.

Yes. Feed-grade bentonite (Microngel BN100) is a non-toxic, inert mineral at normal inclusion levels. It does not significantly affect nutrient digestibility or metabolic functions. Inclusion rates above 2% may reduce feed palatability and should be avoided.

Bentonite is typically used at 0.5–2.0% by weight as a pellet binder in compound feed. Higher inclusion (up to 3%) may be used for specific applications requiring maximum pellet hardness. The optimal rate balances binding performance with feed cost and regulatory limits.
