Program
The 2025 international greenhouse gas and animal agriculture conference (GGAA) meeting will be held 5-9th October in Nairobi, Kenya. (9th GGAA Conference 2025 - International Greenhouse Gas And Animal Agriculture Conference (GGAA)
On the day prior to the meeting on the 5th October 2025, 10am – 4pm EAT – the ICAR Feed and Gas working group and the ASGGN Genetics network of the Global Research Alliance Livestock research group are holding a joint workshop to explore genetic selection for traits associated with greenhouse gas emissions, the latest global initiatives, measurement technology and the impact of breeding schemes on reduction of emissions from livestock
These workshops are aimed to be lively discussions addressing technical aspects of current global challenges – in each 90-minute session we will have 3-4 speakers with the aim to encourage a lot of views, discussion, advice and comments about shared issues. In particular, our focus is on applied research to enable the implementation of breeding schemes.
The meeting will be hybrid, and we invite participants to register by emailing linda.murray@agresearch.co.nz with your name and affiliation. In return you will receive a link to join the web page.
