E-mail: maguilar@intiasa.es We present a novel tool to assess the mitigation potential of nitrous oxide (N2O), methane (CH4) and ammonia (NH3) losses as a consequence of different strategies and techniques implemented on intensive cattle, pig and poultry farms. Considering Management Practices and Climatic Conditions Designed for farm- scale use Inputs typically well known by the farmer A comparison of strategies GASEOUS EMISSIONS PATTERN THROUGHOUT THE YEAR GASEOUS EMISSIONS (NH3, CH4, N2O) IN THE DIFFERENT FARM STAGES FOR 2 STRATEGIES 21% Emission reduction  Feed, water and energy consumption  Animal production  NH3, N2O, CH4 emissions  Solid and liquid manure production and composition  Nutrients in soil  Effects on Faecal Indicator Organisms (FIOs)  The software enables simulation and comparison of the combined effects of different environmental techniques throughout all the farm process, and takes into account specific management and climatic conditions, with the aim of facilitating the selection of the most suitable techniques for a particular situation.  Further tests will be necessary to validate the results provided by this tool.  Animal nutrient balance, considering zoo-technical and nutritional data  Covers  Additives  Separation techniques  Aerobic treatment  Anaerobic digestion  Gravity decantation  Composting  Equipment  Manure Incorporation  Dry matter content in the slurry  Faecal Indicator Organisms (FIOs) - E. coli and coliforms  3-stage qualitative scale TREATMENT  Gas emission factors considering: the type of floor, the frequency of slurry removal, slurry temperature, nitrogen dilution in the slurry, ventilation rates, bedding characteristics, grazing periods and other best available techniques (BATs)  Different nutritional management (adjustment of protein and phosphorus) STORAGE LANDSPREADING HOUSING This work has been funded by BATFARM Interreg-Atlantic Area Project (2009-1/071) MAIN OUTPUTS OF THE MODEL FIOs
