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.

Pork Safety - Post-Harvest
Effects of commercial chilling methods for reducing bacteria on pork carcasses
Previous laboratory studies have demonstrated that snap/blast chilling is known to significantly reduce some bacterial populations on pork surfaces, including Salmonella, Campylobacter, E. coli, and...
Solids, organic load and nutrient concentration reductions in swine waste slurry using a polyacrylamide (PAM)-aided solids flocculation treatment
Increased swine production results in concentration of wastes generated within a limited geographical area, which may lead to land application rates exceeding the local or regional assimilatory...
Simulated N management effects on corn yield and tile-drainage nitrate loss
Thoroughly tested simulation models are needed to help quantify the long-term effects of agriculture. We evaluated the Root Zone Water Quality Model (RZWQM) response to different N management...
Extractable Phosphorus Following Soil Amendment With Manure From Swine Fed Low-Phytate Corn
Manure application rate recommendations have been based almost exclusively on nitrogen (N) management considerations, which can result in over-application of phosphorus (P) and its accumulation in...
An assessment of odour emissions from land applied swine manure
Land application of manure generates more odour complaints than any other stage in livestock production. Livestock odours have been found to be complex and challenging to accurately measure in field...
Movement of faecal bacteria through the vadose zone
The impact of biosolid and soil type on the movement of faecal coliforms through the vadose zone was investigated following the application of animal manure to soil. Two types of biosolid, solid...
Using a Soil Hydrometer to measure the Nitrogen and Phosphorus Contents in Pig Slurries
The hydrometer method to indirectly measure the nutrient contents, i.e. total nitrogen Nt, and total phosphorus Pt of pig slurries was examined against both single and multiple slurry sources. The...
Evaluation of the Carbofil Inernational Downflow Tube Reactor for Treatment of Swine Waste
The Carbofil® biological reactor is a type of down-draft reactor that uses impellers to entrain oxygen and increase the opportunity for that oxygen to dissolve in wastewater. The oxygen is used...
Role of Rhodobacter sp. strain PS9, a purple non-sulfur photosynthetic bacterium isolated from an anaerobic swine waste lagoon, in odor remediation
Temporal pigmentation changes resulting from the development of a purple color in anaerobic swine waste lagoons were investigated during a 4-year period. The major purple photosynthetic bacterium...
