I am a second year Walsh Fellowship PhD student based in Teagasc Grange and registered at University College Dublin. The title of my project is Understanding of the role of diet, host feed efficiency and genetics on the rumen microbiome and environmental outputs in beef cattle.
The need to feed an ever growing global population while also being required to limit the negative impacts on the environment associated with livestock production is a major challenge for global agriculture. Methane originating from ruminant livestock production is responsible for nearly 40% of global agriculture’s emissions, with cattle identified as the main contributor. Here in Ireland in particular, agriculture is the single largest contributor (~30%) to overall Greenhouse Gas emissions, and it is important to develop and implement abatement strategies through dietary management and breeding tools.
