What is the role of a binder in mycotoxin control?

• A. Neutralizing vitamins
• B. Increasing feed palatability
• C. Enhancing microbial growth
• D. Binding mycotoxins in the gut to reduce absorption

Answer: (D)

Binders work by adsorbing mycotoxins in the gastrointestinal tract so they are not absorbed into the bloodstream. This physical binding reduces the amount of toxin that reaches systemic circulation, helping to lower toxicity and improve animal health. They’re selected for their ability to attach specifically to mycotoxins, using materials like clays, aluminosilicates, or yeast cell wall components, which trap the toxins in the gut and promote their excretion. Note that binders aren’t about neutralizing vitamins, nor do they inherently make feed more palatable or encourage microbial growth; their primary role is to prevent toxin absorption by binding the toxins in the gut.
