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...

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...
Development of a Swine-Specific Fecal Pollution Marker Based on Host Differences in Methanogen mcrA Genes
January 1, 2007By Ufnar
The goal of this study was to evaluate methanogen diversity in animal hosts to develop a swine-specific
archaeal molecular marker for fecal source tracking in surface waters. Phylogenetic analysis of...
The fate of crop nutrients during digestion of swine manure in psychrophilic anaerobic sequencing batch reactors
January 1, 2007By D.I. Masse Dairy and Swine Research and Development Centre
The objectives of the study were to measure the levels of manure nutrients retained in psychrophilic anaerobic sequencing batch reactors (PASBRs) digesting swine manure, and to determine the...
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...
Sensitivities of Four Air Dispersion Models to Climatic Parameters for Swine Odor Dispersion
January 1, 2007
Using air dispersion models to predict downwind livestock odor concentrations in order to establish science-based setback distances has the potential to become a common practice for regulatory...
