Dietary manipulation of sulfur for reduced H2S emission from swine waste
This experiment was conducted to evaluate H2S production rates from nursery pig swine manure stored in simulated waste storage pits as influenced by sulfur content of the diets fed. Waste from six...
Ammonia emissions from a High-RiseTM swine finishing facility
Ammonia concentrations of exhaust air from a 960-head, High-RiseTM swine finishing facility and of air downwind from the facility were monitored during the facility's first year in operation,...
Dispersion of Volatile Organic Compounds around Swine Production Facilities in the United States
Dispersion of odors, gases, and particulates from swine production and manure storage facilities creates a problem with neighbors. It is assumed that all materials emitted by production units rapidly...
Anaerobic treatment of animal wastewater for odor control
Anaerobic treatment of pig and dairy manure was studied in the laboratory with 2-stage anaerobic sequencing batch reactor (ASBR) systems. The effects of anaerobic treatment on odour control in...
Nutritive value of timothy fertilized with chloride or chloride-containing liquid swine manure
Chloride fertilization of timothy (Phleum pratense L.) decreases forage dietary cation-anion difference to an acceptable value [(
Odor carrying characteristics of dust from swine facilities
Odour nuisance has become a major problem in the pig industry. Foul-smelling dust plays a major role in the spreading of odour. Gas chromatography equipped with a flame ionization detector has...

Quantifying Volatile Organic Compound Interaction With Particulate Matter For The Development Of Odor Transport Models
A laboratory study of an aerated lagoon bio-blanket for swine manure odor control
The effectiveness of an aerated, submerged bio-blanket for controlling the release of odorous and volatile compounds from pig manure storage lagoons was examined. Hydrogen peroxide was used as an...
Single-component modelling of pig farm odour with statistical methods and neural networks
Pork farm odour has become an increasingly important problem for the pork industry because non-farming rural residents object to the odours coming from pig facilities and insist that it disrupts...
