Mycotoxins are secondary metabolites produced by various species of fungi synthesized at the end of their exponential growth phase. Their presence ins in ruminant feeds can reduce growth, feed intake and negatively impact feed efficiency. In addition, they can also challenge the immune system and cause considerable economic losses.
To prevent mycotoxin contamination of feeds, preference has been given to the inclusion of montmorillonite (main constituent in bentonite) modified by a cationic surfactant to improve the adsorption capacity of mycotoxins. Reasons for this preference are its small particle size, special layered structure, porous properties and its strong ion exchange capability.
