What is the primary benefit of grinding feed?

• A. To reduce particle size for better digestibility.
• B. To increase moisture retention
• C. To enhance flavor with artificial additives
• D. To sterilize feed

Answer: (A)

Grinding feed reduces particle size, increasing the surface area available for digestive enzymes and rumen microbes. With smaller particles, enzymes and microbes can access nutrients more easily, leading to faster and more complete breakdown of starches, proteins, and fiber. This generally improves nutrient absorption and overall feed efficiency, which is why the main benefit is improved digestibility through better enzymatic access. The other options don’t reflect what grinding primarily does: it doesn’t directly boost moisture retention, it doesn’t create flavor through additives, and it doesn’t sterilize the feed—those effects require different processing steps.
