Summary

Ammonia emissions from barns have a severe impact on the environment. Especially dairy cattle, kept in loose housing, contribute to the total emission of ammonia up to 50%. Soiled walking areas like slatted floors, are realised as one of the main sources of the emission. In this study, a special cleaning device was used in order to remove manure from a slatted floor in an organically run dairy barn. It was investigated how the combination of a rubber-scraper, mechanical star discharge rotors and high-pressure water nozzles affects the ammonia emission from the floor. Six concrete test elements (55cm x 62cm x 20cm) were cut out of the existing slatted floor in order to be able to separate them from other sources of ammonia emission in the barn. With a wet-chemistry method, the ammonia emitted from the slatted floor was analysed. Compared to untreated control slats, a reduction of the amount of manure weighted on the clean test elements up to 33.2% could be observed. However, no significant effect of the cleaning of the slats on the ammonia emission could be detected.
