Comparative Analysis of Odor Evaluation and Aerosol Monitoring Techniques
February 21, 2005By Robert von Bernuth
Relative to this project, what one really wants to know about a swine facility is whether odor from the unit can be predicted, how good the prediction would be, and how difficult it will be to...

Influence of Gestation Housing on Sow Welfare and Productivity
January 26, 2005By Roy Kirkwood
The data from this experiment suggests that the mixing of strange sows into groups can be done without adversely affecting fertility. The lack of overall effect on litter size and farrowing rate...
A Planning Tool for Assessing the Relative Contribution of Facility Components to Air Quality Surrounding Pork Production Sites
January 20, 2005
This National Pork Board project resulted in an odor footprint tool (OFT) that is adaptable to regional weather conditions and multiple pork facility layouts. The OFT provides a visual representation...

Evaluation of the effect of group size and structure on welfare of gestating sows in pens with electronic sow feeders
January 18, 2005By John Deen
The present research was an attempt to see how the existing system of commercial group houses with ESF can be made more welfare friendly by modifying the group size and structure. The groups studied...
Loss of Virulence Genes in Escherichia coli Populations during Manure Storage on a Commercial Swine Farm
January 1, 2005By Patrick Duriez
Confined livestock production farms typically store their wastes prior to land application. Here, we employed three complementary approaches to evaluate changes in the population structure and...
