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...
Nutrient concentrations of runoff during the year following manure application
January 1, 2007By John E. Gilley
Little information is currently available concerning temporal changes in nutrient transport following the addition of manure to cropland areas. This study was conducted to measure nutrient transport...
Odor-reduction performance of constructed wetland treating diluted swine manure
January 1, 2007By Eileen F. Wheeler
The odor-reduction capability of livestock wastewater treatment wetlands has been primarily anecdotal and presented as a benefit beyond the already widely recognized attributes. The objective of this...
Nitrogen balance and accumulation pattern in three contrasting prairie soils receiving repeated applications of liquid swine and solid cattle manure
January 1, 2007By C. Stumborg & J. J. Schoenau
The expansion of intensive livestock operations in western Canada has increased concerns about overloading of nutrients in manured lands. The magnitude of nutrient accumulation and its distribution...
Soil-based treatment of partially treated liquid swine manure
January 1, 2007By H. YANG Department of Civil and Environmental Engineering
A soil-column system was tested for the removal of soluble organics and nutrients from partially treated liquid swine manure. The liquid manure was applied to the 900 mm deep (300 mm of local topsoil...
