Hay dry matter intake (DMI), time spent ruminating, and in situ neutral detergent fiber (NDF) disappearance for steers fed distillers grains supplement on alternative days comparing day fed supplement (ALT-SUP) to day not fed (ALT-NSUP) supplement, and at a high (HI) or low amount (LO) amount of supplement (Exp. 2)

Within a row, common superscripts indicate no significant difference between means, P > 0.05.

ALT-SUP = day fed supplement plus hay, ALT-NSUP = day not fed supplement, received hay only.

LO = 0.4% of body weight, HI = 0.8% of body weight. Mean BW = 310 kg.

Rate of NDF disappearance when consuming hay alone was 5.17%.
