Field and Wind Tunnel Evaluation of Vegetative Buffers for Particulate Trapping and Odor Reduction Near Swine Production Facilities
January 14, 2009By Thomas J. Sauer
Growing number of swine operations have turned to natural buffers (also called shelterbelts or vegetative buffers) as part of their odor mitigation strategy. However, there is little to no data on...

Inactivation of PRRSV using ultraviolet light
November 11, 2008By Jeffrey Zimmerman
The objective of this study was to calculate the inactivation of PRRSV by dose of UV254 in a “static” (i.e., virus-in-liquid solution) system. This study is the first step in...
