Whole wheat inclusions had substantially greater impacts when added post-pelleting in comparison to pre-pelleting inclusions. Post-pellet inclusions increased relative gizzard weights, reduced gizzard pH and the incidence of dilated proventriculi. Post-pellet whole wheat improved FCR by 4.25%, increased AME by 0.81 MJ and ME:GE ratios by 6.00% (0.742 versus 0.700). Post-pellet whole wheat inclusions reduced distal ileal starch concentrations by 50.4% (7.21 versus 14.53 g/100 g). The advantages of whole grain feeding which appeared to be driven by greater extents of starch digestion allied to heavier relative gizzard weights.
