Emission of Ammonia and Other Contaminant Gases from Naturally Ventilated Dairy Cattle Buildings

The emission rates were dependent on floor type and manure-handling method. The lowest ammonia emission was found for buildings with solid floors with smooth surface, scraper and drain. For buildings with slatted floors, manure treatment with acid, scraper on the slatted floor surface or channel scraper are potential alternative methods for reduction of the ammonia emission.
