Broiler litter ammonia emissions near sidewalls, feeders, and waterers.
Ammonia (NH3) volatilized from broiler litter diminishes indoor air quality, which can potentially decrease bird productivity. Emissions of NH3 exhausted from broiler houses pose environmental concerns for ecosystem biodiversity, aquatic nutrient enrichment, and particulate formation in the atmosphere. Research was conducted sampling litter (rice hull base) in 3 tunnel-ventilated commercial bro...
متن کاملEvaluation of Ammonia Emissions from Broiler Litter
Ammonia (NH3) emissions from poultry litter results in air pollution and can cause high levels of NH3 in poultry houses, which negatively impacts bird performance. The objectives of this study were to: (1) conduct a nitrogen (N) mass balance in broiler houses by measuring the N inputs (bedding, chicks, and feed) and N outputs (birds marketed, mortality, litter/cake, NH3 emissions, and nitrous o...
متن کاملReduction of Salmonella and Ammonia Emissions in Broiler Litter Using Sulfuric Acid and Aluminum Sulfate
In recent years an emphasis has been placed on reducing food borne pathogens on the farm. Of particular interest to the poultry industry is Salmonella enterica. In the United States, a common practice in broiler management is the reuse of litter for consecutive flocks; this practice can lead to a Salmonella positive flock causing the colonization of sequential flocks. Reuse of litter can also l...
متن کاملAmmonia Emissions from USA Broiler Chicken Barns Managed with New Bedding, Built-up Litter, or Acid-Treated Litter
Poultry producers in the United States have attempted to maintain barn aerial ammonia (NH3) levels below 25 ppm to improve air quality, and more recently to decrease aerial emissions to the atmosphere. Our objective was to investigate the influence of litter management strategies on NH3 emissions from commercial broiler barns employing new bedding, acid-treated built-up litter (sodium bisulphat...
متن کاملEffects of liquid aluminum chloride additions to poultry litter on broiler performance, ammonia emissions, soluble phosphorus, total volatile Fatty acids, and nitrogen contents of litter.
Recent studies have shown that the use of aluminum sulfate [alum, Al2(SO4)3.14H2O] and aluminum chloride (AlCl3) additions to animal manures are more effective than other chemicals in reducing ammonia (NH3) emissions and P solubility. Although the use of Al2(SO4)3.14H2O has been intensively used in the poultry industry for many years, no research has been conducted to evaluate the effect of liq...
