Not only are years-long delays in agricultural building procedures now being observed - in Upper Austria, Styria and Burgenland there is also the possibility under building law for the authorities to intervene retroactively in existing and approved barns.
Several options exist in practice for influencing ammonia and odor emissions from broiler poultry – either by reducing protein intake or by using ActiProt® as an alternative protein source (see final report on the EmiProt project, DaFNE No. 101024/1), or by adding additives during feed production. This final report of the EmiProt II research project presents the results of the trials with feed additives from Jadis Additiva and Lithos Natural GmbH.
Before implementing alternative protein sources or feed additives on a widespread basis, the poultry industry requires reliable data on the effects of the components used. In the present series of trials with products from Jadis Additiva and Lithos Natural GmbH, potential influences on fattening performance (daily weight gain, final weight, feed conversion), on the release of harmful gases (ammonia and carbon dioxide), and on odor emissions in poultry fattening were investigated. Four fattening cycles were conducted for each test series.
