| To evaluate the effects of the composition of total mixed rations (TMR) and ensiling of the TMR on rumen fermentation properties and methane production, we compared two types of TMRs, which were optimized for dairy cattle and beef cattle, and their ensiled TMRs (eTMR). To make eTMRs, TMRs were wrapped and fermented for 40 days. These eTMRs and TMRs were used for in vitro ruminal incubation experiment. The type of TMR and ensiling both affected total short chain fatty acids, the amount of methane production, and relative proportions of acetate and butyrate in the in vitro rumen cultures of tested TMRs. The relative abundance methanogenic archaea in respective cultures determined by quantifying a gene involved in methane production (mcrA: α-subunit of methyl co-enzyme M reductase) was also affected by both the type and the ensiling, which was higher in the eTMRs than the TMRs (p<0.001). The results of the present study suggest that not only ensiling TMR but also the composition of TMR may affect in vitro rumen fermentation patterns, and that changes in the degree of methane generation due to ensiling TMR may also depend on the fermentation kinetics.
