     REMRUM ProjectReduction of methane emissions from dairy cows and concurrent improvement of feed efficiency obtained through host genetics and next-generation sequencing of rumen microbiome.

    The REMRUM project is a collaboration between scientists from Aarhus University, the Technical University of Denmark, the Danish Cattle Research Centre and Viking Genetics. The project also involves researchers from the University of Vermont, USA, the Veterinary Medical University in Vienna and the United States Department of Agriculture, USDA.

    The project's base hypothesis is that there is a quantitative variation in the microflora of the rumen which is partially controlled by the cow's genotype. The micro-flora can thus be considered an independent organism with a quantitative variation, which interacts with the cow as the other organism,

    The aim of the project is to clarify the complex connections between the cow's genetics, the genetics of her micro-organisms, the cow's feed efficiency and its methane emission and will clear the way for reducing the methane production whilst optimising feed efficiency. This would benefit both the farmer's budget and the environment.

    The four-year project is largely funded by the Danish Council for Strategic Research, Programme Commission for Health, Food and Welfare.
