How to Breed Climate-Friendly Dairy Herds

How to Breed Climate-Friendly Dairy Herds

When methane emissions that contribute to global warming are blamed on cows, they should, more precisely, be blamed on the microorganisms that live inside them. It stands to reason, therefore, that in seeking ways to reduce methane emissions from the dairy and beef industries, researchers’ primary target should be cows’ microbiomes. In line with this perspective, a group of researchers with teams in four countries recently carried out a detailed analysis of the microorganisms living in the rumens of different herds and breeds of cattle. These researchers have identified a population of bacteria, protozoa, anaerobic fungi and archaea that consistently form the core population of the rumen microbiome. By linking microbiome components to phenotypes such as methane emissions, they propose the establishment of microbiome-led breeding programs as a means to make livestock farming more climate-friendly.
