This study evaluated the effects of seven biochar products at two levels of inclusion (2.25 or 4.50 % diet DM) on DM disappearance (DMD), cumulative gas and methane (CH4) production, ammonia-nitrogen and VFA production from Timothy grass hay over 48 h of incubation. Biochar did not affect gas and CH4 production (P≥0.17) nor the DMD or ruminal fermentation (P≥0.12). In conclusion, the biochar, irrespective of level of inclusion, did not exhibit potential to mitigate CH4 emission in a grass hay diet.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
