I have been working on factors influencing methane production in ruminants, by modeling methane production and validating the models predicting methane production in dairy cows, with specific emphasis on diets fed in Northern latitudes. Currently, my main research interest is methane production form dairy cows, factors to inhibit emissions of methane and techniques for measuring gases from ruminants.
The main measurement method I am currently dealing with and responsible for, is the GreenFeed method (C-lock). The in vitro gas production method is the alternative method for estimating methane production in dairy cows. I coordinate a number of studies in which involves the use of the gas in vitro method and the GreenFeed system.
