Abstract

Background: A negative impact on livestock productivity and the environment due to accumulation of greenhouse gases, might be mitigated by using secondary metabolic compounds from plants in the form of tannins which potentially proven in reducing the methane production of ruminants. This study aims to explore the Fodder Trees Species (FTS) in terms of nutritional value, energy metabolism content and its potential as an inhibitor of methane gas produced in rumen fermentation. Methods: This research was carried out in two stages. Phase I, evaluation of the nutritional value of the FTS which includes a proximate analysis and analysis of the NDF and ADF fiber fractions components. Phase II, the evaluation of FTS with in vitro gas methods. The study was carried out in a Completely Randomized Design (CRD) consisting of 6 species of FTS as treatment and 4 replications. Profil GP and metan production are measured at incubation time of 3, 6, 9, 12, 24, 48 and 72 h. DM digestibility, OM digestibility, N-amonia and energy metabolism were measured at the end of in vitro gas study. Result: The Species of FTS has varied chemical composition, potential nutritional value and not only provides protein but also a source of energy for ruminant animal. At incubation times of 12 to 24 hours, the production of methane gas from M. oleifera, S. grandiflora and L. leucocephala is greater than that from G. sepium and C. calothyrsus. However, at incubation times exceeding 24 hours, C. calothyrsus produces more methane gas than P. falcataria and G. sepium. The highest levels of N-ammonia are produced by M. oleifera, L. leucocephala, S. grandiflora and C. calothyrsus, while the lowest levels are observed in P. falcataria and G. sepium. P. falcataria and G. sepium found as the potential low methane-producing feeds and have protein characteristic which are resistant to rumen microbe digestion.
