Effect van strooiselverwijdering bij leghennen in volièrehuisvesting op de emissie van ammoniak, geur, broeikasgassen en fijnstof

Research output: Book/ReportReportProfessional


This report summarizes the results of measurements performed in the framework of the programmatic Approach nitrogen (PAS) to determine the effect of removing litter from livestock housing of laying hens (to maintain a thin layer of litter in the animal building) on the emission of ammonia, fine dust, odour and greenhouse gases (methane, nitrous oxide). Removing the litter led to significantly lower emissions of NH3 and PM10 (on average 20-22% lower emissions). Although in seven of all nine measurements removing the litter resulted in lower odour emissions (~25% emission reduction), no significant effect was found of removing the litter on odour removal. For CH4 and N2O, removing litter did not result in significantly lower emissions. When a thin litter layer (less than 2-3 cm) can be maintained, a reduction of 25-35% in NH3 and PM10 emissions may be achieved.
