Mycotoxins are toxic compounds produced by mold growth in feed ingredients. The most critical mycotoxins affecting swine are vomitoxin, zearalenone, ochratoxin, and fumonisin, which can be produced by molds that appeal to the genera, fusarium, aspergillus, and penicillium.
Mycotoxin contamination prevention incorporates pre- and post-harvest strategies. Interventions carried out in the field to stop a fungal infestation, such as tillage, crop rotation, insect fungicides. You can find the best toxin binders in your area.

Acidifiers are generally used as mold inhibitors, particularly organic acids like propionic acid. Acidifiers display fungicidal properties by reducing the pH in feed and grain.
Mycotoxin binders or adsorbents are chemicals that bind to mycotoxins and also protect against absorption through the intestine.
The most widely used mycotoxin binders in swine feeds are aluminosilicate binders, which include bentonites, clays, and zeolites.
The aluminosilicate binders are organic, inorganic mycotoxin binders comprising a porous structure made of silica that's able to absorb and trap mycotoxins. Aluminosilicate binders are nonspecific and bind vitamins and trace minerals as well.
Additional mycotoxin binders used in swine feeds are yeast parts. The yeast parts are natural mycotoxin binders extracted from the cell walls of Saccharomyces cerevisiae, primarily α-and β-glucans. The yeast components have a diverse mechanism of adsorption and act against a vast selection of mycotoxins.
Organic yeast components are biodegradable and do not accumulate in the environment after being excreted in manure compared to inorganic silicate binder.
