Mitigation of methane and nitrous oxide emissions from livestock production

Animal production is a significant source of greenhouse gas (GHG) emissions worldwide. As part of a stream of activities carried out by FAO to identify low GHG emission pathways for the livestock sector, FAO has just published "Mitigation of greenhouse gas emissions in livestock production: A review of technical options for non-CO2 emissions" written by A.N. Hristov, J. Oh, C. Lee and co-authors and edited by P. Gerber, B. Henderson and H.P.S. Makkar. The 206-page publication evaluates the potential of enteric fermentation (i.e. fermentation of feed in the rumen as part of the normal digestive processes of livestock), manure and manure management and, thirdly, animal husbandry practices for mitigating methane and nitrous oxide, i.e. non-carbon dioxide (non-CO2), GHG emissions from livestock production. The section on animal husbandry also covers use of recombinant bovine somatotropin as well as artificial insemination and other reproductive technologies.
