Currently, due to environmental and economic issues, ruminant production system has aimed at maximizing production, concomitant with an increased efficiency. Because of methane is produced in the process of feed energy utilization within the animal, its reduction is usually associated with improved productivity. Therefore, one of the strategies to optimizing energy use in ruminants is to minimize enteric methane (CH₄) emission during the fermentation process, by reducing dry matter intake (Shibata and Terada, 2010). Feed restriction is a common practice on goat production in several parts of world, and can be used to exploiting the compensatory gain, resulting in better efficiency of animal feed energy utilization. Therefore, this study was carried out to evaluate the effect of feed restriction on methane emission and digestibility.
