Reduction 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 کاملWinter broiler litter gases and nitrogen compounds: Temporal and spatial trends
Understanding how animal activities, management, and barn structure affect litter gases and nutrients is fundamental to developing accurate emission models for meat-bird facilities. This research characterized the temporal and spatial variability of litter ammonia (NH3) and nitrous oxide (N2O) flux via a chamber method, as well as determined litter nitrogen (N) compounds by intensive sampling i...
متن کاملReducing phosphorus runoff and improving poultry production with alum.
This is a review paper on the effects of aluminum sulfate (alum) on ammonia volatilization and P runoff from poultry litter. Initially, laboratory studies were conducted that showed P solubility could be reduced in poultry litter with Al, Ca, and Fe amendments, indicating that these amendments may reduce P runoff. These results were confirmed in small plot studies in which alum applications to ...
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 کاملNitrogen emissions from broilers measured by mass balance over eighteen consecutive flocks.
Emission of nitrogen in the form of ammonia from poultry rearing facilities has been an important topic for the poultry industry because of concerns regarding the effects of ammonia on the environment. Sound scientific data is needed to accurately estimate air emissions from poultry operations. Many factors, such as season of the year, ambient temperature and humidity, bird health, and manageme...
