| Research Abstract |
The dairy cow is so heat stress-sensitive that countermeasures against recent global warming should be necessary in dairy farming. On the other hand, methane gas derived from dairy cow body, estimated to be 25% of global emission, is the major source along with the paddy rice cropping in agriculture. In order to reveal the influence of heat stress on methane and the carbon-dioxide emissions, which are exerted by the physiology state of a dairy cow, the monitoring system was constructed by using a carbon dioxide gas analyzer. The dynamic chamber method should be operated as far as certain flow conditions, otherwise a fluid analysis should be used during the night time to enhance the accuracy of the gas flux evaluation.
