An in vitro experiment was conducted to determine the component(s) and concentration of BG or DG causing methane production to decrease. The following substrates were incubated: increasing concentrations of BG or DG from 0 to 100% replacing alfalfa, increasing concentrations of corn oil from 0 to 10% replacing corn gluten feed (CGF), BG and DG with and without lipid, corn gluten feed with 3% yeast or 14% beer, and 80% BG or DG with 20% grass hay.

520 $a An in vitro experiment was conducted to determine the component(s) and concentration of BG or DG causing methane production to decrease. The following substrates were incubated: increasing concentrations of BG or DG from 0 to 100% replacing alfalfa, increasing concentrations of corn oil from 0 to 10% replacing corn gluten feed (CGF), BG and DG with and without lipid, corn gluten feed with 3% yeast or 14% beer, and 80% BG or DG with 20% grass hay.
520 $a Methane (percent of non-lipid GE) production was linearly decreased (P < 0.01) as BG was increased from 20 to 100%, whereas 100% DG was required to decrease (P < 0.01) methane. Adding 0 to 10% corn oil to CGF linearly (P < 0.01) decreased methane production. Incubating non-lipid BG or DG did not alter methane production. Incubating beer with CGF increased (P < 0.01) methane production 50%, whereas yeast had no effect. A mixture of 80% BG with grass hay decreased (P < 0.01) methane (percent of nonlipid GE) production, whereas incubation of 80% DG with grass hay had no effect.
520 $a The in vivo experiment used six steers to evaluate methane decreasing effects, nutrient digestibility, and energy value of diets containing 0, 20, or 40% DG as part of a 60% concentrate diet in a 3 x 3 Latin square. Methane production was not significantly decreased by DG addition. Adding 20 and 40% DG to the diet increased (P < 0.05) NDF digestibility 17 and 30%, respectively when compared to the control at 46.7%. Digestible energy was 6.8% greater (P < 0.05) for the diet containing 40% DG than the other diets. Similar to DE, ME (Mcal/kg DM) content of the DG diets was 7% greater (P < 0.05) for each 20 percentage unit addition of DG. The NEm and NEg content of the DG diets were at least 10% greater (P < 0.05) than the 1.95 and 1.56 Mcal/kg found for the control. Calculated by difference and extrapolated to NRC (1996) equivalents, the NEg content of the DG alone is approximately 1.83 Mcal/kg DM, about 20% above the current estimate.
