Daily supplement DMI from week 1 to 7 (day 0 to 45) of Nellore heifers offered free choice access to warm-season grass hay and receiving trace mineral supplement (TM), sugarcane molasses cooked block (LMB), pair-fed protein supplement (PSPF), and a commercial protein supplement (PS) from day 0 to 45 (n = 100 heifers; five heifers/pen; five pens/treatment). Effects treatment × week were detected for average daily supplement DMI (P < 0.0001). Supplement DMI of PS heifers did not differ from week 1 to 7 (P ≥ 0.62), whereas supplement DMI of TM, PSPF, and LMB tended to increase on week 7 vs. all previous weeks (P ≤ 0.10) ^a–cWithin a week, means without a common superscript differed (P ≤ 0.05).
