Rebecca Danielsson
Researcher at the department of applied animal science and welfare


Research Interests
Ruminant nutrition: Focus on methane production from dairy cows. 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 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.
