Evaluation of a Pilot-Scale Electro-nanospray System for Decontaminating Pig Barns
In this study, an electro-nanospray system was developed for pig barn decontamination. This technology generates engineered water nanostructures (EWNS) through electrospraying and ionization of reverse osmosis (RO) Water. The highly charged nano-scale water droplets encapsulate reactive oxygen species (ROS), which are responsible for bacterial inactivation...

New and alternative sanitization procedures for antibiotic-free swine barns
Certain barns that switched to antibiotic-free production observed increased prevalence of pathogens after a few years on the program. Developing improved sanitization and disinfection procedures is an important step to reduce the pathogen load in antibiotic-free barns, which was the goal of this study. This project identified...

Testing of a rapid detection kit for Porcine Epidemic Diarrhea virus (PEDv)
Significant economic losses can result from outbreaks of Porcine Epidemic Diarrhea (PED), a serious disease currently circulating in North American swine herds. Accurate and rapid detection of PEDv is essential to expedite implementation of control measures for the disease. A rapid PEDv test kit is...

Design criteria for cleanability, worker safety and welfare characteristics of pig transport trailers
Disease transmission associated with transportation of pigs has been a long-standing issue affecting biosecurity in pig production. In addition, stress responses and welfare are greatly influenced by the trailer compartment configuration. The overall goal of this study was to develop a trailer design criteria checklist...

Impact of antibiotic-free production on pathogen occurrence and prevalence of antimicrobial resistance
This study assessed the impact of Raised Without Antibiotics (RWA) production practices on on-farm antibiotic use, pathogen occurrence, and the prevalence of antimicrobial resistance genes (ARGs) through the whole genome sequencing and analyzing of samples (fecal, manure, sow nasal swab, soil). Some farms that provided...
