摘要	Methane (CH(4)) production in the rumen represents a loss of energy for the host animal; in addition, methane eructated by ruminants may contribute to a greenhouse effect or global warming. The dinumal CH(4) and carbon dioxide (CO(2)) emissions from sheep were continuously recorded using the flow-through chamber method. A type new type of non-disperse infrared (NDIR) gas sensors based on pulse IR source was introduced, and by using the high performance pyroelectric IR sensor with built in interference filter and the "single light and two wavelengths" technology, CH(4) and CO(2) measurement from ruminants was achieved. Animals were given dry oat hay as the basic diet and supplemented concentrate with the ratio of 7:3. The results showed that the recovery was 96.7% and 96.2% for CH(4) and CO(2), respectively. Methane and carbon dioxide output from sheep respectively averaged 15.6 g per day and 184.7 g per day, equivalent to 6.8 and 71.1 kg per animal. Diurnal fluctuations in hourly rates of CH(4) and CO(2) production in hourly of methane increased during day light to reach a peak at or near sunset and then declined towards sunrise, and consideration was given to the dry matter intake of the animals used in these studies and its possible effects on CH(4) production.; Methane (CH(4)) production in the rumen represents a loss of energy for the host animal; in addition, methane eructated by ruminants may contribute to a greenhouse effect or global warming.
