RumenStability - Understanding the development and control of stability in the rumen microbiome as a basis for new strategies to reduce methanogenesis

Contact: PD Dr. Björn Kuhla

Duration: 2014-2019

Funding: Bundesministerium für Ernährung und Landwirtschaft, European Research Area

The project addresses 3 overall goals: 1.) to implement early life treatments as a methane mitigation strategy and understand the basis for the long-term effects of these treatments, 2.) to understand the basis for host effects on the rumen microbiome, and 3.) to identify and understand the basis for non-genetic differences between animals in their response to anti-methanogenic compounds, as well as differences in the persistency of responses. An animal study involving dairy cows during 1st lactation and a study on calves fed divergent levels of collostrum and milk replacer provide the basis for studying methane production, rumen digesta kinetics, development of the rumen and immune system in association with the rumen microbiome and the stability of the rumen microbial community.
