A metabolism study was conducted to evaluate dietary sulfur (S) in beef cattle finishing diets formulated with wet and dry distillers grains with solubles (DGS) containing low (0.82%) and high (1.16%) S concentration. There was no interaction between moisture and S for intake, DM digestibility, or hydrogen sulfide (H2S). Steers fed low S DGS consumed more feed than steers fed high S DGS. Subtle differences were observed for ruminal pH variables. Propionate and butyrate concentrations decreased when high sulfur DGS was fed. Sulfur of DGS impacts intake, VFA, and ruminal H2S concentration. Wet DGS may be more prone to conversion of S to H2S in the rumen than dry DGS.
