Methane is the second-largest greenhouse gas after carbon dioxide in contributing to global warming, which is the main driving to climate change. The emission of methane from enteric fermentation was the greatest contributor to agricultural emissions. Controls the component in the feed is one of the strategies for the reduction of methane emission from the rumen. The aim of this study was to determine the effect of different concentrate composition on methane emission and energy utilization in

The treatment was the different composition of protein (P) and energy (TDN) of their feed. The treatments included T1 (P 8.28%, TDN 56.70%), T2 (P 8.53%, TDN 61.30%), T3 (P 9.81%, TDN 57.70%) and T4 (P 10.09%, TDN 61.26%) with three replications in each treatment. There were no differences in gross energy intake, digestible energy, energy digestibility, and methane emission. The results of gross energy intake, digestible energy, energy digestibility, and methane energy were 2.67 MJ/kg BW 0.75 /day, 1.80 MJ/kg BW 0.75 /day, 67.09% and 7.78 MJ/100 MJ GEI, consecutively. The difference in concentrate composition does not have any adverse effect on methane emission.
