Estimation of Ammonia Emission from Manure Belt Poultry Layer Houses Using an Alternative Mass-Balance Method
Ammonia (NH3) emission from animal feeding operations (AFOs) has caused concerns on public health and environmental degradation, such as ecosystem acidification, eutrophication, and formation of PM2.5 fine particles. Current ammonia emission measurement methodologies are accurate and reliable, but time consuming, expensive, and impractical for most facilities. In the present study, an alternati...
متن کاملAmmonia Emission from Fattening Pig Houses in Relation to Animal Activity and Carbon Dioxide Production
Ammonia emission from animal facilities is a world-wide research focus area, because ammonia is a nuisance for the external environment. It is therefore important to know how ammonia emissions depend on various factors, such as animal activity and ventilation rate. The objective of this paper is to show the impact of animal activity on the variation of the diurnal ammonia emission in controlled...
متن کاملEvaluation of chemical amendments to reduce ammonia volatilization from poultry litter.
Ammonia volatilization from poultry litter often causes high levels of atmospheric ammonia in poultry houses, which is detrimental to both farm workers and birds. Ammonia emissions from houses also aggravate environmental problems, such as acid rain, and result in a loss of fertilizer nitrogen. The objectives of this study were to determine the effect of litter amendments on ammonia volatilizat...
متن کاملAmmonia concentration and relative humidity in poultry houses affect the immune response of broilers.
To investigate the effect of ammonia (NH3) and humidity on the immune response of broilers, broilers were exposed to 30 or 70 mg/kg atmospheric NH3 for 21 days. Additionally, birds were exposed to 35, 60, and 85% relative humidity (RH). The relative weights of lymphoid organs, serum total protein, serum globulin, serum albumin, serum lysozyme, proliferation index of peripheral blood lymphocytes...
