| dc.description.abstract | At the Institute of Agricultural Engineering of the University of Hohen- heim, a swine housing system with fully slatted floor (FSF) and a freely ventilated kennel housing system (KHS) are being compared as part of continuous emission measurements with the goal of assessing the envi- ronmental impact of fattening pig husbandry systems. To secure the re- liability of the data, it is first necessary to examine the quality of the measurement, the methodological approach, and the execution of the tri- al. Subsequently, the criteria for data selection are determined taking the sensitivity of the emission measurements into account before the data are used for a comparison of the emission rates. When measuring the gas concentrations of ammonia (NH3 ) and methane (CH4 ), a water vapour cross sensitivity of the measuring instruments of 0.23 and 0.65 ppm/g H2 O/kg of air respectively must be taken into ac- count. Especially in the case of CH4 , this closely restricts the usability and significance of low concentration values if the water content of the sample air ranges between 10 and 20 g/kg of air. A comparison of the carbon dioxide (CO 2 ) concentration at two heights with the background concentration allows currents of leaking air at the air inlet of the natu- rally ventilated housing system to be detected with high temporal reso- lution. For these periods, it is impossible to determine the emission ra- tes. When the course of the gas concentrations in the slurry store is con- sidered, the kennel housing system shows an influence of the inlet air temperature on the air exchange through the slatted floor. The CO 2 con- centrations observed in both systems indicate that, as compared with the animal-specific portion, conversion processes in the excrement are re- sponsible for a larger part of the gas release than previously assumed. | en |
