Larissa Zetouni

During her studies, Larissa Zetouni focused on opportunities to perform genetic selection on dairy cows that produce, and therefore emit, less methane. Methane is a potent greenhouse gas (GHG), and livestock is directly responsible for 18% of global GHG emissions, therefore mitigation strategies directed to lowering the emission potential from cattle is of extreme importance when aiming for more sustainable livestock systems. The findings in this project contribute to better understanding of the complexity behind methane production as a selection trait, which constitutes the first step before considering implementing methane production in selection indices and breeding goals across the globe.

The PhD degree was completed at the Department of Molecular Biology and Genetics – Quantitative Genetics and Genomics (QGG), Science and Technology, Foulum, Aarhus University.

This résumé was prepared by the PhD student.
