For 30 d before the start of data collection and throughout the study, heifers had ad libitum access to primary diet treatments of either total mixed ration with 12% forage (as fed, low roughage, n = 6) or 100% Sudan grass hay (high roughage, n = 6).

^aTreatments were compared based on the percentage of final bodyweight heifers pushed. Data for 1 heifer in the low-roughage treatment, identified in brackets, were excluded from final comparisons for this measure.

^bThe number of days each heifer pushed the gate is indicated. Weight was added to the 27-kg gate daily in 34-kg increments.
