Treatments were arranged in a 2 × 3 factorial with the main effects of feeder adjustment and diet form. The 2 feeder adjustments were a narrow feeder adjustment (minimum gap opening of 0.50 in.) and a wide adjustment (minimum gap opening of 1.00 in.). The feeders were adjusted to the minimum gap setting, but the agitation plate could be moved upward to a maximum gap opening of 0.75 or 1.25 in. for the narrow and wide adjustments, respectively. The 3 diet forms were meal, poor-quality pellets (50% pellets and 50% fines), and screened pellets with minimal fines. Average daily gain, ADFI, and F/G were determined by weighing pigs and measuring feed disappearance on d 0, 12, 22, 39, 48, and 69. No diet form × feeder adjustment interactions were observed (P > 0.24). For Phases 1 (d 0 to 22) and 2 (d 22 to 48), feeder adjustment did not influence (P > 0.28) ADG, but ADFI tended to increase (P < 0.07) and F/G worsened (P < 0.05) for pigs fed from the wide adjusted feeders. In Phase 3 (d 48 to 69), no differences were detected in growth performance (P > 0.17) between pigs fed from either feeder adjustment.en-USSwineDiet formFeeder adjustmentPelletFinishing pigConference paper
