Interaction of PRRSV and Porcine Dendritic Cells: Potential Role in Viral Persistence
Porcine reproductive and respiratory syndrome virus (PRRSV) may persist in tissues of pigs for months. How the virus persists in certain pigs remains to be determined. It is possible that a subset of...

Macrophage cell-lines for in vitro propagation of porcine reproductive and respiratory syndrome virus
Vaccination of pigs against PRRSV is the most prudent and logical way of controlling this economically important disease. Production of vaccines requires large scale propagation of PRRSV in the...

Fate of Estrogens in Pig Waste
As discussed earlier, about 2.3 x 108 kg of manure is generated each day in the US by the pig industry. Manure is land applied because its value in supplying nutrients to crops as well as of...

Effect of Feeding System Failures on Grow-Finish Performance and Welfare
Results of these 2 experiments document the impact of repeated out-of-feed events on grower-finisher pig performance. Repeated out-of-feed events that are 20 hours long results in a decrease in daily...

Development of a Killed Subunit PRRS Vaccine
The focus of our research funded by the National Pork Board was to develop second generation killed PRRS vaccines. The portion of the PRRS virus responsible for stimulating the neutralizing immune...

Air Emissions Monitoring Protocol
H2S concentrations measured at the perimeter of nine swine operations across the state indicated that for the sizes of operations investigated with this study, the dominating influence on perimeter...

Influence of animal handling and transportation factors on the welfare of slaughter pigs during transport and incidences of deads and downers
This research evaluated three factors (namely feed withdrawal prior to transportation, mixing of pigs from different groups on the trailer, and floor space on the trailer) potentially associated with...

Construction of Dynamic Aerosol Toroid Chambers
PRRSV costs the US swine industry 560 million dollars each year in lost productivity. We can now successfully eliminate PRRSV from individual farms, but we cannot keep herds from becoming...

Relationship between Antibiotics in Water and Rates of Antimicrobial Resistance Gene Transfer
There is growing concern about the fate of antibiotics and antibiotic residues in the environment. These compounds can potentially have selective effects on bacteria, thus amplifying the resistance...

A pilot project to determine the feasibility of controlling PRRS within a selected region
The purpose of this project was to determine if pork producers within a defined region were willing to test their herds for PRRS virus, share the results with other cooperating producers, and share...
