What is the most expensive form of feed processing?

• A. Pelleting, due to its three-step process
• B. Crumbling
• C. Grinding
• D. Extrusion

Answer: (A)

Pelleting tends to be the most expensive form of feed processing because it adds multiple processing steps that require specialized equipment and energy. The typical pelletizing sequence includes grinding the ingredients to the right particle size, conditioning the mash with steam and moisture to plasticize and bind the mix, and forcing it through a pellet die to form pellets, followed by cooling to harden the product. Each step—grinder, conditioner, pellet mill, cooler, and associated controls—adds capital cost, energy use, and maintenance. Those cumulative costs make pelleting more costly than simple grinding or crumbling. Extrusion can be energy-intensive as well, but it’s a different process with its own cost structure; the three-step pelleting sequence commonly drives higher overall costs in many feed systems.
