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 (<em>p </em>&gt; 0.05) of different ration composition on the ultimate methane yield (<em>B</em>0) of goat feces. This study found that <em>B</em>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.</p><p><strong>Conclusion: </strong>Feeding grass and legume can reduce methane respiration emission in goat. <em>B</em>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.</p><p>J.
