¹Fiber concentrations quantified at 7-d intervals; and CP and IVTDMD measures quantified at 14-d intervals.

²In vitro true dry matter digestibility.

³Control: cottonseed meal, 0.45 kg DM/animal-daily; DDGS: dried distillers grains plus solubles, 0.50% mean paddock BW/animal-daily.

^a,bWithin column, means without a common superscript differ at P ≤ 0.05.
