[Investigations on the concentration and emission of ammonia and nitrous oxide in various deep litter keeping systems for fattening pigs and in slatted floor keeping].
Concentration of ammonia and nitrous oxide was measured in an air conditioned pig site with two chambers during six rounds (app. 650 measuring days) with different deep litter and a slatted floor keeping system for fattening pigs. Emissions and gaseous nitrogen losses were calculated. With exception of a system with mixing twice a week deep litter keeping leads to decrease of NH3 concentration (up to 26%), partly also of NH3 emission, but to higher N2O emissions compared to liquid manure system. With exception of ENVIROZYME deep litter keeping all other deep litter systems cause higher gaseous nitrogen losses compared to slatted floor keeping.
