Abstract

The study evaluated dry matter degradation and methane gas emissions from sugarcane top-fermented to substitute grass. The first part of the research was to process sugarcane top using Phanerochaete chrysosporium (PC) and Cytophaga sp (CS) compared to sugarcane top without fermentation (SC). The second part of the research was to evaluate the degradability characteristics of unfermented sugarcane top (SC), fermented sugarcane top using Cytophaga sp (CS) and grass (G) which were measured in sacco for 0, 2, 4, 8, 12, 16, 24, 48, and 72 hours and methane gas emissions were measured in vitro. The experiment was carried out using RAL and replicated 3 times in sacco and 5 times in vitro. Results showed that the protein content of SC (4.52%) was less than PC (5.87%) and CS (5.71%), but there was no significant difference (P>0.05) between both PC vs. CS. Results of in sacco dry matter (DM) degradability test showed that the amount of dissolved fraction (a) from CS was not significantly different (P>0.05) with SC but was lower (P<0.05) than G. The number of fractions degraded at a specific time (b) and the degradation rate (c) of CS, SC and G were similar, but the degradability values for 24, 48, and 72 hours incubation of CS and SC were lower than that of G. The highest methane emission per DM degradability produced in CS = 34.4 ml/g followed by SC = 27.6 ml/g and G = 27.3 ml/g. It can be concluded that the processing of sugarcane top through fermentation can increase the protein and energy content. Although the DM degradation of fermented sugarcane top was low, the methane emission was higher than that of grass, indicating that sugarcane top fermentation can not replace grass function.
