Evaluation 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 کاملBroiler 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 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 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 کاملMitigating Ammonia Emissions from Liquid-Sprayed Litter of Cage-Free Hen House with a Solid Litter Additive
A number of restaurant chains, retailers, and grocers in the US have pledged to source cage-free (CF) eggs only in the foreseeable future (e.g., by 2025 or 2030) due to marketing reasons or concerns over animal welfare. However, CF housing has some inherent challenges and a predominant one is poor air quality (ammonia gas – NH3 and particulate matter – PM) and increased emissions. The high NH3 ...
