¹The high-forage diet was fed from d 1 to d 105 (backgrounding phase) followed by sequential adaptation (transition phase) to a high-grain diet (finishing phase, 105 d).

²Determined using ingredient from samples pooled every 3 wk within each phase; all values except DM are expressed on a DM basis.
