Feed Particle Size: Generally, smaller mash particle size
enhances pellet quality since the material has a larger
surface area that allows heat and moisture from steam to
more quickly and thoroughly penetrate the particle. Smaller
particles also have more surface area to adhere and bind to
other particles in the pellet. However, the cost of grinding
to obtain smaller particle sizes needs to be weighed against
the benefits of improved pellet quality. From a cost-benefit
standpoint, the optimal particle size for corn-soy poultry
diets may be in the 650 to 700 micron range [Dozier, 2001]
