^a-bWithin a row, means without a common superscript differ (P ≤ 0.05).

*Monday, Wednesday, and Friday = days when all steers received concentrate supplementation; Tuesday, Thursday, Saturday, and Sunday = days that concentrate supplementation was offered to 7-3X and 7X steers (d 0 to 15), or only to 7X steers (d 16 to 42).

^†Pen as the experimental unit (three steers/pen; four pens for 7X and five pens for 3X and 7-3X treatments).

^‡ P value for effects of supplementation frequency × day of supplementation.
