1Control: cottonseed meal, 0.45 kg DM/animal-daily; DDGS: dried distillers grains plus solubles, 0.50% mean paddock BW/animal-daily.
2DM: dry matter; OM: organic matter; NDF: neutral detergent fiber; ADF: acid detergent fiber; CP: crude protein; NEm: net energy for maintenance; NEg: net energy for gain.
3Calculated from model predicted intake and mean nutrient concentration across sampling days.
4Calculated from forage mass availability and nutrient concentration.
