Rebecca Danielsson
My research focuses on nutrition in ruminants, mainly the parameters that affect cow methane production. Both parameters that can generally affect all cows such as feed and feed additives, but also individual variations in feed utilization as well as the microbial composition in the rumen.


Research Interests
Ruminant nutrition with focus on methane production from dairy cows. Rumen microbiology, especially methane producing microorganisms; methanogens (Archaea)

Research Goal
Identify differences in methane production from cows fed different types of feed and differences between individuals fed the same diet. A further aim is to find out if it could be possible to correlate methane production with some certain species or groups of microorganisms in rumen.

Research Skills
Design, sampling, analysis and interpretation of methane measuring studies, microbial analysis and in vitro experiments.


Ongoing projects:


Is it possible to combine high forage consumption with low methane emissions from milk cows? In collaboration with; Cecilia Kronqvist,  Anna Schnürer, Maria Åkerlind. Finansierat av SLF 2017-2021

Can the red algae Asparagopsis taxiformis reduce methane production in dairy cows? In collaboration with; Mikaela Lindberg, Sophie Krizsan och Mohammad Ramin. Formas 2020-2022

Part in projects;

Improved sustainability in dairy production by increased feed efficiency, SLF 2019-2022

Improving pasture utilization by using the natural variation in cows’ grazing behaviour and herbage nutrient content, Ekoforsk 2020-2022
