Effect of a manure additive on ammonia emission from swine finishing buildings
January 1, 2000
The effect of a commercial manure additive (Alliance) on ammonia (NH3) emissions was evaluated in commercial 1000-head grow-finish swine buildings over a six-month period. The test was conducted in...
Ammonia Volatilization and Selected Soil Characteristics Following Application of Anaerobically Digested Pig Slurry
January 1, 2000
Ammonia volatilization occurs shortly following land application of pig slurry. Several slurry and soil characteristics modulate the intensity of this process, and their net effect on volatilization...
Removal of dimethyl disulfide and p-cresol from swine facility wastewater using constructed subsurface-flow wetlands
January 1, 2000
Anecdotal evidence suggests that constructed wetlands can remove odors from veal, dairy, and swine wastes (Murphy and George, 1997; McCaskey, 1995). However, the use of constructed wetlands as an...
Corn response to composting and time of application of solid swine manure
January 1, 2000
Swine production in hoop structures is a relatively new husbandry system in which a mixture of manure and bedding accumulates. This manure/bedding pack can be applied to crop fields directly from a...
THE EVALUATION OF WELFARE IN EARLY WEANED PIGS AS MEASUREDBY ADAPTABILITY

Evaluation of a permeable, 5 cm thick, polyethylene foam lagoon cover
January 1, 2000
Anaerobic lagoons and liquid manure storage basins are widely used for the treatment and storage of livestock and poultry manure. Although relatively inexpensive to construct, these devices have been...
Dynamics of Pig Slurry Nitrogen in Soil and Plant as Determined with 15N
January 1, 2000
The fate of pig (Sus scrofa) slurry labeled with 15N was investigated when applied on a clay soil (fine, mixed, frigid, Typic Humaquept) and a sandy loam (loamy, mixed, frigid, Typic Dystrochrept)...

Conceptual model for ammonia and odor production and ammonia emission from swine anaerobic lagoons
January 1, 2000
A model that predicts the concentration of ammonia and volatile fatty acids as odor indicators was developed for anaerobic lagoons using Monod kinetics. The model used average measured parameter...
Evaluation of two-stage anaerobic sequencing batch reactor systems for animal wastewater treatment
January 1, 2000
Anaerobic treatment of screened swine and dairy manure was studied in the laboratory with two-stage anaerobic sequencing batch reactor (ASBR) systems. The effects of anaerobic treatment on odor...
