Abstract


Eight buifalo heifers of about nine months old with body weight 164 kg were
used for detemtining methane emission. They were kept in individual barns and
allowed rice straw ad libitum as a basal diet. Methane measurement was done by
face-mask method equipped with Methane analyser (Horiba Ltd, Japan) and airflow
meter that automatically recorded in [BM PC. Methane emitted was analysed for 10
minutes at 3 hours intervals in 24 hours. The total methane emission per ten minutes
was then converted to daily total emission. Dry matter intake was averaged from
four days prior CH4 measurement. The results show that daily methane emission was
34.08 g/kg DMI. By using this result, the bulfaloes in Indonesia that mostly fed rice
straw contribute methane for 166 Gg/year and it is about 3.54% of total methane
emission from all sectors that reported as 4687 Gg/year.
