Assessing the impact of swine sulfur intake from drinking water on odor and gaseous emissions and manure nutrients
February 12, 2007By Bernardo Predicala
To assess the impact of inputs to the pig on air quality and manure management, a study was conducted to assess the effect of varying sulfate levels in drinking water on odor and gaseous emissions...

Identifying the Genetic Profile of the Salmonella-carrier Pig to Improve Food Safety and Decrease Pre-Harvest Disease
February 1, 2007By Shawn Bearson
Pigs that shed Salmonella in their feces are an animal health issue, a food safety problem and an environmental contamination risk. Our research program investigates the undesirable carrier state of...

Macrolide, lincosamide, and streptogramin B (MLSB) resistance in soils amended with swine manure
February 1, 2007By Julie Zilles
The land application of treated swine manure has been proposed to contribute to the spread of antibiotic resistance, but this possibility has not been confirmed. In this work we measured antibiotics...
Automated Image Analysis for Quantitative Fluorescence In Situ Hybridization with Environmental Samples
January 1, 2007
When fluorescence in situ hybridization (FISH) analyses are performed with complex environmental samples, difficulties related to the presence of microbial cell aggregates and nonuniform background...
Nitrogen mass balance in fields irrigated with liquid swine waste
January 1, 2007
Over the past 15-years, swine-producing confined animal feeding operations (CAFOs) have proliferated throughout the Southeastern United States, particularly in North Carolina. Waste at these...
Multiple environmental externalities and manure management policy
January 1, 2007
This paper considers the economic and environmental implications of regulation the air nitrogen emissions under single and multi-environmental media policies in the US hog industry. We examine...
Phosphorus Losses through Agricultural Tile Drainage in Nova Scotia, Canada
January 1, 2007By R.D. Kinley
Tile drainage water from agricultural fields commonly exceeds environmental guidelines for phosphorus (P) in rivers and streams. The loss of P through artificial drainage is spatially and temporally...
Simulating management effects on crop production, tile drainage, and water quality using RZWQM-DSSAT
January 1, 2007By L. Ma USDA-ARS
The objective of this study was to explore if more crop-specific plant growth modules can improve simulations of crop yields, and N in tile flow under different management practices compared with a...
Use of Anaerobically Digested Swine Manure as a Nitrogen Source in Corn Production
January 1, 2007By John E. Sawyer
Swine (Sus scrofa) manure is an important source of N for crop production. The processing of manure in an anaerobic digester for biogas production is only a partial manure treatment process and is...
Temporal Dynamics and Impact of Manure Storage on Antibiotic Resistance Patterns and Population Structure of Escherichia coli Isolates from a Commercial Swine Farm
January 1, 2007By Edward Topp|Patrick Duriez
Many confined-livestock farms store their wastes for several months prior to use as a fertilizer. Storing manure for extended periods could significantly bias the composition of enteric bacterial...
A novel use of anaerobically digested liquid swine manure to potentially control soybean cyst nematode
January 1, 2007By JUN ZHU
Experiments were carried out in two steps to determine the effect of anaerobically digested swine manure on soybean cyst nematode (SCN) egg control. In the first step, liquid swine manure underwent...
