  • 摘要:Objective: This study aimed to evaluate the respiratory methane emission and ultimate methane yield ( B 0) of goat feces that fed roughage consisted of Pennisetum purpureum and Gliricidia ) and fed roughage and concentrate with different protein source in the ration (fish meal and soybean meal). Materials and Methods: Fifteen Kacang bucks were allocated to the control group (T0): goats were fed roughage only, T1: goats were fed roughage and concentrate with fish meal as protein sources, and T2: goats were fed roughage and concentrate and the protein source in the ration was soybean meal. Results: The protein content of feces from T0 was significantly lower ( p < 0.05) than that from the other treatments. The same phenomenon was also found in the respiratory methane emission in terms of l/head/d, l/kg digestible dry matter, and l/kg body weight. However, there was no significant effect ( p > 0.05) of different ration composition on the ultimate methane yield ( B 0) of goat feces. This study found that B 0 of goat feces from treatment T0, T1, and T2 was 17.40%, 25.78%, and 61.29%, respectively, higher than that from the international default value for developing countries. Conclusion: Feeding grass and legume can reduce methane respiration emission in goat. B 0 of feces in the present study was higher than that in the international default value; therefore, the potential emission of goat manure in tropical developing countries could be higher than that in the present estimation.
