Increasing dietary inclusion of CPC linearly reduced (P < 0.05) the CATTD of GE, diet DE and calculated NE values for Phase 1 and 2. Increasing dietary inclusion of CPC did not affect overall (d 0–35) ADFI and ADG of pigs, but quadratically reduced (P < 0.05) ADFI for day 29–35, linearly increased (P < 0.05) ADG for day 15–21 and linearly reduced (P < 0.05) ADG for day 29–35
