英文摘要: Due to its potential environmental and public health impacts, emissions of ammonia (NH3) as well as several other gases from US livestock farms may be regulated. Broiler houses are important sources of NH3 emissions. However, there are no emissions data from roaster (8-12wk old broilers, ~4kg ea.) houses. Producers treat the litter in broiler houses with acidifiers, such as sodium bisulfate (SBS, NaHSO4) to reduce ammonia production and protect bird health. However, there is very little data on the effect ofacidifiers, particularly at high application rates on ammonia emissions. The impact of different SBSapplication rates [High (0.95-1.46kgm-2, whole house), Medium (0.73kgm-2, whole house), Low (0.37-0.49kgm-2, whole house), and Control (0.37-0.49kgm-2, brood chamber)] on ammonia emissions was evaluated in commercial roaster houses over 22 months spanning eight flocks. Ammonia emission from each fan was measured with an acid scrubber that operated only when the fan operated. Emissions were calculated using ≥95% measured data with the rest being estimated using robust methods. Exhaust ammonia-N concentrations were inversely correlated with the SBSapplication rates. Emission rates on animal unit (AU, where 1 AU=500kg live-mass) basis (ER, gd-1AU-1) were reduced by 27, 13, and 5%, respectively, in the High, Medium, and Low treatments vs. the Control treatment (mean: 100gd-1 AU-1, range: 86-114gd-1 AU-1). Emission rates for the Control treatment measured in this study on roasters were mostly higher than ERs in the literature. Differences in ERs are not only due to diet, environmental and management conditions, but also due to measurement methods. © 2013 Elsevier Ltd. Citation statistics:
