Fibrous Clays - Feed Ingredient

Fibrous clays refer to a group of naturally occurring clay minerals characterized by a fibrous or thread-like crystalline structure. Common types include attapulgite (also known as palygorskite) and sepiolite. These clays are primarily composed of hydrated magnesium aluminum silicates and possess a unique chain-like morphology that contributes to their absorbent and binding properties.

In equine feed formulations, fibrous clays are primarily used as anti-caking agents, pellet binders, or mycotoxin binders. Their absorbent nature helps in managing moisture content and enhancing the physical integrity of feed pellets. As mycotoxin binders, they can adsorb certain harmful toxins, reducing their bioavailability in the digestive tract and potentially mitigating their adverse effects.

Due to their non-specific binding properties, fibrous clays may also adsorb beneficial nutrients, medications, or supplements in the digestive tract. This can reduce the bioavailability of certain compounds, necessitating careful consideration of inclusion levels and interactions when formulating diets.
