Sammanfattning

The building had 164-195 Holstein dairy cows. The milk production was 31-33 kg cow(-1)d(-1). Manure gutters beneath the partially slatted floor in the building were scraped twice a day. Measurements took place during the winter when the cows were permanently indoors and during 1 week in the spring when the cows were indoors at night and outside grazing during the daytime. The indoor concentrations were measured at nine evenly distributed locations, while outdoor concentrations were measured at two locations. The mean ventilation rate in winter was 250-26S m(3) LU(-1) h(-1) and in spring, it was 401 m(3) LU(-1) h(-1). The emissions of NH3 and CH(4) were in the range of 0.89-1.13 and 9-13 g LU-1 h-1, respectively. A strong positive correlation was found between enhanced CO(2) and CH(4) concentrations.
