The Effect of Different Inclusion Levels of Corn Starch and Fine Ground Corn With Different Conditioning Temperature or Die Thickness on Pellet Quality

Feeding a greater percentage of whole pellets to poultry and swine provides return on investment for producers. Pellet binders are commonly used in commercial feed mills, but the added cost has limited their use mills. Corn starch could be potential natural binder as it is biomass pellet operations. Therefore, objective these experiments was determine effect different inclusion levels corn fine ground with conditioning temperature or die thickness quality. In, Experiment 1, treatments were arranged 3 × 2 factorial design level (0%, 5%, 10%) (1/2 in. 7/8 in.). In 2, 10%, 20%) (175 185°F). For Exp. there by interaction (P = 0.033; Table 3) durability index (PDI). Increasing concentration from 0 10% diet decreased PDI when diets pelleted using ½ thick die. However, no evidence difference increased There an between modified PDI. 1/2 0.001) linear decrease < increased. > 0.541). increasing inclusion. 175 185°F 0.0001) standard conclusion, pure not effective binding agent contained at least 60% corn. The ratio small particles large did impact quality conditioned above 175°F 35 s then 5.6 L:D improved
