Hi! I am Peter Lund, professor in Sustainable Dairy Production at Aarhus University, Denmark. My research area is ruminant nutrition with an emphasis on the interaction between nutrition, animal genetics and rumen microbiome and on feed additives and feeding strategies that can facilitate significant reductions in enteric methane. I give advice to public authorities on the climate and environmental impact of cattle production with special emphasis on feed additives and feeding strategies to reduce enteric methane, and inclusion of this in the national inventory system.
