Reducing greenhouse gas emissions from livestock production

Cattle are a major source of non-CO2 greenhouse gas emissions: methane (CH4), nitrous oxide (N2O) and ammonia (NH3). This collection reviews the range of research on ways of reducing greenhouse gas (GHG) emissions from livestock production. Part 1 reviews the genetics, measurement and modelling of methane emissions from cattle. Chapters cover what we know about rumen function and genetics in relation to methane emissions, ways of measuring and modelling emissions. Part 2 reviews the contribution of breeding, housing and husbandry practices including manure management. Part 3 assesses nutritional approaches to reducing emissions, from forage and silage to feed supplements such as plant bioactive compounds and direct-fed microbials as well as inhibitors and vaccines to modify the rumen environment.
