1A total of 90 pigs (PIC [Hendersonville, TN] 327 × 1050, initial BW 12.1 ± 0.25 kg) were used in a 7-d preference trial with five pigs per pen and six replications per comparison.
2Corn used in diets was ground using two sets of rolls, three sets of rolls, four sets of rolls in a fine-grind configuration, and four sets of rolls in a coarse configuration.
3Feeders were rotated once daily within each pen to eliminate any location effects of feeder.
4ADFI, % is a percentage of total feed intake for each treatment within a comparison.
