The Art (Science) Of Pelleting (Part 1)

Published: December 6, 2017
Summary
Pelleting has been, and continues to be, a popular processing technique in feed manufacturing. 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...

It would be interesting to read more about the data on high quality pelleted feed and their impact on animal performance. I'll be honest, I am more familiar with shaped products through extrusion of ingredients. There are definitely many overlapping benefits including homogenization of ingredients, pellet durability, and improved pellet consistency. One difference between pelleting and extrusion is that extrusion generates significantly more heat through friction than pelleting which deactivates microorganisms and pathogens and ensures proper expansion of the pellet. Proper expansion and cooking ensures improved digestibility of the proteins and energy in the ration. In addition, extrusion also offers the versatility to create many different sized and shaped pellets. I would like to learn more about the animal performance data regarding pelleted feeding to compare to my knowledge of extrusion.
