The project has three main objectives. The first is the development of nutrition strategies that will lead to a
reduction of greenhouse gas and ammonia emissions in ruminants, i.e., animals that contribute to emissions
most significantly. Part of the first objective is an insight into the mechanism of action of strategies through
observing the effect on the composition of the rumen microbiome using molecular genetic methods. The
second objective is to develop and implement technologies that will reduce greenhouse gas and ammonia
emissions from manure management. The third objective is to update the data input to the national inventory
of emissions from cattle, mainly nutrient digestibility values that are currently outdated.
