Aarhus University, DK
The agricultural sector is a major contributor of global anthropogenic greenhouse gas emissions with enteric methane accounting for up to 40%. Beef and dairy production is therefore under pressure for significant reductions. The presentation will quantify the importance of ruminants in a Danish agricultural context and include the biological background for enteric methane production and ways of measuring enteric methane in trials, as well as differences between breeds, dietary manipulation, and the use of current and upcoming feed additives aiming at reducing enteric methane production without compromising production.

The cattle rumen is a complex fermentation vat inhabited by a multitude of microbial species acting synergistically to convert plant materials into nutrients during feed digestion. Methane is a by-product of this essential process, however there is evidence that more feed efficient cattle emit less methane. The presentation will outline the importance of feed efficiency, how it is measured, its relationship with methane emissions and the role of rumen microbiome in controlling feed efficiency and methane emissions from ruminants. It will also describe the establishment of the rumen microbiome from birth and the identification of the window of opportunity for early life interventions to reduce methane emissions and enhance feed efficiency.
