¹DM: dry matter; OM: organic matter; NDF: neutral detergent fiber; ADF: acid detergent fiber; CP: crude protein; IVTDMD: in vitro true dry matter digestibility; IVTOMD: in vitro true organic matter digestibility.

²Control: cottonseed meal, 0.45 kg DM/animal-daily; DDGS: dried distillers grains plus solubles, 0.50% mean paddock BW/animal-daily.

³S: supplement type; D: grazing day; S × D: supplement type × grazing day interaction.

⁴Measure at d 42 lower (P ≤ 0.0001) than all other d; no other differences (P ≥ 0.70).

⁵Measure at d 0 lower (P ≤ 0.004) than all other d; d 56 higher (P ≤ 0.0002) than all other d; no other differences (P ≥ 0.33).

⁶Measure at d 28 lower (P = 0.04) than d 56 and tended (P = 0.14) to be lower than d 42; d 56 higher than d 0 and 14 (both, P = 0.02); no other differences (P ≤ 0.16).
