In Irish systems, broiler litter is allowed to build up during the 37 day growing cycle, after which it is removed and used for either land spreading or mushroom compost production. It is important to monitor key indoor environmental parameters in order to optimize bird performance but also to comply with legislation such as the EU National Emissions Ceilings Directive. This study used Off Axis - Integrated Cavity Output Spectroscopy to evaluate the ammonia and water vapor content of air within an Irish broiler house. Three broiler cycles were measured at different times of the year to account for seasonal variation, covering spring, summer and autumn. This paper examines the difference in ammonia and water concentrations at 1 m, 2.5 m, and 4 m above floor level following the flow of air from the ground through to the exhaust fan. Autumn had the highest concentration of ammonia indoors throughout the cycle with an average of 1.23 ppm, while summer had the lowest concentration for the majority of the cycle, though increased by a spike towards the end with an average of 0.69 ppm.||Funding Details:||Environmental Protection Agency||Type of material:||Conference Publication||Publisher:||ASABE||Keywords:||Ireland; Ammonia; Broiler; Water vapor; Chicken; Agricultural waste||DOI:||10.13031/aim.20162461252||Other versions:||http://www.asabemeetings.org/||Language:||en||Status of Item:||Not peer reviewed||Conference Details:||American Society of Agricultural and Biological Engineers (ASABE) Annual International Meeting, Orlando, Florida, USA, 17-20 July 2016|
