Abstract
This paper describes the development and validation of a housing system for growing-finishing pigs with anintegrated solution for source oriented measures to reduce emissions of ammonia, greenhouse gases(methane), and odor. In the development phase a simple calculation tool was used to make an estimate ofthe ammonia emission that could be expected. In the validation phase the system was tested on two farmsin a case-control setup. Preliminary studies were done to determine the effect of cooling and flushing on theammonia emission. From this study the following can be concluded: - a rather simple model can be veryuseful in design studies to reduce (ammonia) emissions; - cooling of manure is effective in reducing ammoniaemissions, but is less suitable in combination with a biogas digester; - ammonia emission only showed a minorrise during flushing of manure; - the designed low emission housing system, with daily removal of manure,small emitting area and diluted manure, lowered ammonia emissions by 54%, methane emissions by 90%, andodor emissions by 28%; - reductions of ammonia and odor can be increased by good management of thewhole system
