Carrying Capacity for Ruminant Based on Plantation Byproducts and Potency of Enteric Methane Emission

Feed is one of the main pillars that need to be considered in optimizing production parameters order develop an efficient livestock business. Two aspects make agricultural byproducts as a source feed; those are availability raw materials for animal rations with high economic value and function reduce environmental pollution. Methane emissions not only related problems, but also reflect loss some energy from so it cannot used process. The purpose this paper review estimate carrying capacity ruminant based on plantation by-products feed potential enteric methane emissions. Indonesia estimated at 69.6 million tonnes dry matter (DM), 34.8 total digestible nutrient (TDN), 5 crude protein (CP)/year can accommodate 62.4 unit (LU) DM or 39.1 LU TDN 51.6 CP availability. From these calculations, was found could still increased much greater than current population, namely 21.7-45 units if all entirely components rations. There two groups originating produced, low (65-73 g CH4 / kg material) (83-103 material). Utilization expected overcome shortage forage, especially during season. which line efforts would enhance development populations friendly environment.
