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.

Evaluation of dietary butyrate as a growth promotant and on the response to lipopolysaccharide (LPS) in weanling pigs
Due to traditional feedstuffs for swine being diverted to biofuels, feed costs for pork production have increased dramatically. Consequently, pork producers are seeking ways to increase the...

Global Gene Expression Profiling of PRRSV-infected Alveolar Macrophages
This study examined the effect of porcine reproductive and respiratory virus (PRRSV) on how genes are expressed in porcine alveolar macrophages (PAMs). PAMs were chosen for this study because they...

E. coli O157:H7 prevalence and characterization from NAHMS 2006 swine fecal samples
The objectives of the current study were to use the 2006 swine NAHMS samples to determine the prevalence, antimicrobial characterization, and genetic profile of E. coli O157:H7 in the U.S. swine herd...

Particulates, Ammonium Nitrate, and Ammonium Sulfate: Effects on Air Quality in Rural Iowa
Air quality has many components, one of which is PM2.5 and ammonium nitrate and ammonium sulfate are reported to be two of the major components. Swine confinement facilities generate significant...

Expanding the immune toolkit for assessing pig health and improving swine disease and vaccine studies
Swine disease and vaccine research will be advanced by the development of sophisticated tools to measure swine antibodies or immunoglobulins (Igs). Swine produce antibodies, or Igs, in response to...
Pork Safety - Pre-Harvest
Quantitative evaluation of selective factors impacting the development, amplification, persistence and transfer of macrolide resistance elements within mixed populations of commensal and pathogenic gut bacteria.
A series of laboratory experiments were conducted to assess the effects of low (25 ug/ml) or high (100 ug/ml) tylosin treatment on potential development, amplification, persistance and transfer of...

Understanding health-related microbial, odor, and ammonia fate following swine lagoon wastewater application by center pivot irrigation
Microorganisms are present in animal wastewater. These microorganisms may include those important in human and animal disease. Animal wastewater may also contain ammonia and compounds that produce...

Developing a Decision Support Tool to Optimize Swine Production Facility Layout to Minimize Downwind Air Quality Impacts
These model experiments of air flow characteristics suggest that when swine confinement buildings are oriented so that the approaching wind is parallel to the buildings the wind is reduced less than...

Implementation of a PRRSV Strain Database (Renewal)
A PRRSV ORF5 database, accessible worldwide, was improved for swine producers, practitioners and researchers (http://prrsv.ahc.umn.edu/). This database, established to fulfill one objective of the...
Pork Safety - Pre-Harvest
Sequencing of 10 potential molecular epidemiological targets from a collection of food safety relevant Salmonella spp.
The development and testing of molecular epidemiological tools for pre-harvest food safety applications is an important and rapidly evolving issue. This means that it is vital to track bacterial...
