A Planning Tool for Assessing the Relative Contribution of Facility Components to Air Quality Surrounding Pork Production Sites
January 20, 2005By Dennis D. Shulte
This National Pork Board project resulted in new odor planning tools called “odor roses” and “odor footprints” that provide visual representation of the frequency, direction and extent of...
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...
Dietary strategies for reduced phosphorus excretion and improved water quality
January 1, 2005
Cost effective feeding strategies are essential to deal with P surpluses associated with intensive animal agriculture and the consequent impact on water quality. Reduction of P overfeeding, use of...
Performance of a Lab-Scale Sequencing Batch Reactor with Addition of Carbon in Removing Nutrient and Organic Matter in Liquid Swine Manure
January 1, 2005By JUN ZHU
The influence of carbon addition on performance of a lab-scale, anaerobic-anoxic-anaerobic-anoxic sequencing batch reactor ((AO)2SBR) in biologically removing nitrogen and organic matter from liquid...
Determination of odor-annoyance-free setback distances from animal production sites: Part II. Model development and evaluations
January 1, 2005
The OFFSET (Odor from Feedlots - Setback Estimation Tool) model was developed to estimate the setback distances from animal production sites in Minnesota. It is based on odor emissions taken from...
Laying the Groundwork for Odor Control and Setback Estimation in Nebraska
January 1, 2005By Richard R. Stowell
The goal of this field research study was to validate use of the Odor Footprint Tool (OFT) with livestock building sources in rural communities. The primary objective was to evaluate the accuracy of...
