Pork Quality
Pork Checkoff Research
Research is at the heart of the National Pork Board’s mission and is funded by your Pork Checkoff dollars. Research is administered in all areas of pork production, processing, and human nutrition to develop a higher quality and more profitable product in the competitive meat protein market.

Dietary adipic acid reduces ammonia emission from swine excreta
Adipic acid is only partially catabolized when it is fed to animals, and a portion of it is excreted in urine. The excreted portion may lower urinary pH and, as a result, ammonia emission. The...
Nitrogen mineralization and uptake by ryegrass in a clay loam soil amended with composts or liquid pig manure
Although composted liquid pig manure is increasingly being applied to agricultural soils, little is known about its impacts on N dynamics (mineralization, denitrification, immobilization, and plant...
Ammonia volatilization from marsh-pond-marsh constructed wetlands treating swine wastewater
Ammonia (NH3) volatilization is an undesirable mechanism for the removal of nitrogen (N) from wastewater treatment wetlands. To minimize the potential for NH3 volatilization, it is important to...
Laboratory and In-Situ Reductions of Soluble Phosphorous in Swine Waste Slurries
Laboratory and field experiments were conducted using magnesium chloride (MgCl2) to force the precipitation of struvite (MgNH4PO4.6H2O) and reduce the concentration of soluble phosphorous (SP) in...
Hydrogen sulfide assessment in shallow-pit swine housing and outside manure storage
In Saskatchewan, some recent incidents have lead us to believe that certain manure management activities can potentially release high concentrations of H2S into the atmosphere of shallow-pit barns....
Effects of feedstock pH, initial CO addition, and total solids content on the thermochemical conversion process of swine manure
The effects of feedstock pH, ratio of initial carbon monoxide to volatile solids (CO/VS), and total solids content of the feedstock on the thermochemical conversion process of swine manure were...
Biological anoxic/aerobic treatment of swine waste for reduction of organic carbon, nitrogen, and odor
A continuous-flow anoxic/aerobic (A/A) biological treatment system designed to treat swine wastewater was investigated. Laboratory studies were conducted to determine the heterotrophic bacteria...
