Method and apparatus for reduction of ammonia, carbon dioxide and pathogens in chicken housesA chicken or fowl grow out facility utilizes a ventilated floor assembly including a ventilated floor through which liquid and gas can flow, but which retains manure deposited thereon, and a closed bottom ...
more poultry houses will be needed. Therefore, it is important to investigate ways that poultry facilities can coexist in close proximity to residential areas without odors and environmental challenges. Ammonia (NH3) is the greatest concern for environmental pollution from poultry production. When birds...

EMPIRICAL MODELS TO DETERMINE AMMONIA CONCENTRATIONS FROM BROILER CHICKEN LITTER Volatilization of ammonia from poultry litter in broiler houses creates potential health hazards for the house operator and the birds. This problem was add... LE Carr,FW Wheaton,LW Douglass - 《Transactions of the Asae》...
An ammonia gas (NH3) generator was developed to maintain a set concentration of ammonia gas in a controlled environment chamber to study poultry physiological responses to sustained elevated levels of ammonia gas. The goal was to maintain 50 parts per million (ppm) of ammonia gas in a 3.7 m ...
Ammonia is the main harmful gas in livestock houses. However, the toxic mechanism of ammonia is still unclear. Therefore, we examined the effects of ammonia exposure on different tissues of fattening pigs by histological analysis and transcriptome techniques in this study. The results showed that th...
In poultry houses NH3 is produced from the biological process of liter, manure, and protein composition. It has been well documented that NH3 adversely effects the health of chickens. However, the underlying mechanism of NH3 toxicity on chicken thymus is still unknown. Thymus is an important ...
aBut then farms began to use new ventilation systems. Instead of windows, the new systems used tunnel fans to circulate air. The fans directed airflow from the poultry houses toward the homes of neighbors.[translate] aThe trees capture dust, ammonia and odors in their leaves. They also provid...
Evaluation of different methods for determining ammonia emissions in poultry buildings and their applicability to open facilities In regions of tropical and subtropical climates, nearly all installations used for intensive broiler chicken production and other animals of economic inter...

The ammonia emissions from animal housing systems include emissions in animal houses and manure storage facilities. Ge et al. (2020) pointed out that allocating housing emissions evenly within each NCU was a source of uncertainties in the emission model. Therefore, animal housing locations are useful...
