AgResearch Science Impact Leader Robyn Dynes said methane and nitrous oxide levels can be reduced on-farm and discussed mitigation options to reduce greenhouse gases with rural professionals. Dr Dynes mentioned four options currently available to farmers or being worked on. These were low methane feeds, low methane animals, methane inhibitors and a methane vaccine. Low methane feeds could reduce methane levels by about 25 percent. Methane inhibitor work is being carried out by AgResearch, and ongoing methane vaccine research is being conducted. The other gas, nitrous oxide, had two mitigation options: managing soil and soil processes and managing feed.
