Abstract

This report describes the results of emission measurements on 18 Dutch dairy farms between October 2018 and February 2020. Goal of the measurements was to determine the average methane emission (CH4) from dairy housing and the variation within and between farms and to explore the effect of different farm characteristics on the emission. These farms could be characterized by animal breed (HF vs MRIJ), type of management (organic vs non-organic), floor type (slatted floors vs solid floors) and inclusion in the ‘Koeien en Kansen’ project. Beside methane emissions also emissions of ammonia (NH3) and nitrous oxide (N2O) have been measured. The average emission ± standard deviation (SD) was 189 ± 54 kg CH4 per animal place per year, 13,4 kg ± 3,2 kg NH3 per animal place per year and 0,59 ± 0,24 kg N2O per animal place per year. None of the emission differences based on farm characteristics was significant. Emission levels of methane and nitrous oxide were higher than measured on dairy farms between 2008 and 2012. Further analyses of all measurements including continuous emission measurements till November 2020 will be available in a next report.
