In basic terms, pelleting converts a finely ground blend of ingredients into dense, free flowing agglomerates (pellets). There are many reasons used to justify the process, but it may be appropriate to list just a few:
• improved animal performance,
• decreased feed wastage,
• reduced selective feeding,
• improved bulk density,
• better material handling characteristics,
• destruction of deleterious organisms, and
• customer expectations.
Pelleting operations are not without cost. It is a fairly expensive process in terms of both capital and variable costs, but the expense is usually justified in improved plant profit as well as animal performance. The purpose of this paper is to discuss the pelleting process in terms of operations and to describe how the success or failure of the operation can impact on profits as well as animal performance.
