The most important question: what method to use if you need to measure CH4? The answer may be: it depends on what you like to do. In the Table 7 we summarize some experimental conditions and designs, and make recommendations.
| Table 7. Recommendations for measuring methane in diverse experimental conditions and designs.
| ||
|---|---|---|
| Experimental condition and design | Methane measurement method recommendation | |
| Need to measure absolute methane values – animal numbers and location not important | Respiration chamber;
SF6; GreenFeed | |
| Need to rank animals from low to high methane emission | Sniffer method | |
| Need to measure methane on farm | Sniffer method;
GreenFeed; PAC | |
| Low budget measurements needed | Proxy;
Proxies measurement | |
| High animal numbers required | Sniffer method;
Proxies measurement; LMD | |
