The pelleting and crumbling process compacts the mixed feed ingredients and increases nutrient density and bulk density. For some species, pelleting improves palatability or acceptability of feeds. As mentioned above, the steam conditioning that occurs just before pelleting may improve digestibility. The heat generated during compaction of the pellet may also improve digestibility and destroy thermolabile toxic factors that naturally occur in some plant products. Pelleting enhances the availability of phosphorus in wheat bran and also permits the use of low density, bulky, unpalatable feeds that might not otherwise be practical to use.
