Ruminal pH on supplemented days starting at feeding (0630 h) in forage-fed steers supplemented with various frequencies of dried distiller’s grains plus solubles (DG). CON = only hay; DG7 = hay and 0.4% of BW as DG DM daily; DG2 = hay daily and 0.8% BW DG every other day; DGA = alternate day feeding of hay and 0.8% of BW as DG. Treatment × time (P < 0.001). †DGA differs from other treatments (P ≤ 0.05). ‡DG7 differs from other treatments (P ≤ 0.05).

Total VFA concentration on nonsupplemented days for steers fed varying frequencies of dried distiller’s grains plus solubles (DG). CON = only hay; DG7 = hay and 0.4% of BW as DG DM daily; DG2 = hay daily and 0.8% BW DG every other day; DGA = alternate day feeding of hay and 0.8% of BW as DG.

The (acetate + [2 × butyrate]):propionate ratio on supplemented days for steers fed varying frequencies of dried distiller’s grains plus solubles (DG). Ratio calculated as [acetate + (2 × butyrate)]/propionate. CON = only hay; DG7 = hay and 0.4% of BW as DG DM daily; DG2 = hay daily and 0.8% BW DG every other day; DGA = alternate day feeding of hay and 0.8% of BW as DG. Treatment × time (P = 0.03). £DGA differs from DG7 and DG2 (P ≤ 0.005). DGA differs from all other treatments (P ≤ 0.04).
