If a pelleted feed tends to crumble, which component is most likely responsible for improving pellet integrity?

• A. Binding agents
• B. Antioxidants
• C. Preservatives
• D. Ionophores

Answer: (A)

Pellet integrity comes from components that act as adhesives between the ground particles during pelleting. Binding agents create a cohesive matrix, helping the feed bind together under heat and pressure and stay intact as it cools and is handled. This adhesive effect reduces crumbling and improves durability, so the pellet keeps its shape and stays intact through processing, storage, and feeding.

Antioxidants protect fats from oxidation, preservatives extend shelf life by inhibiting microbial growth, and ionophores modify rumen fermentation and performance. None of these primarily enhances the physical cohesion of the pellet, which is why the binding agent is the one most directly responsible for improving pellet integrity.
