Swine Health - PRRS
Construction of Dynamic Aerosol Toroid Chambers
January 18, 2006By Jeffrey Zimmerman
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
January 12, 2006By Randall Singer
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...
Swine Health - PRRS
A pilot project to determine the feasibility of controlling PRRS within a selected region
January 12, 2006By Robert Morrison
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...
Effect of lime, dicyandiamide and soil water content on ammonia and nitrous oxide emissions following application of liquid hog manure to a marshland soil
January 1, 2006By M. S. Mkhabela
The loss of nitrogen (N) from field-applied animal manure through ammonia (NH3) volatilisation and nitrous oxide (N2O) emission is of major environmental concern. Both lime and dicyandiamide (DCD)...
Using stream bioassessment protocols to monitor impacts of a confined swine operation
January 1, 2006
The processing of waste from confined animal feeding operations (CAFOs) presents a major environmental challenge. Treatment of waste and subsequent land application is a common best management...
Ammonia emissions from swine waste lagoons in the Utah Great Basin
January 1, 2006
In animal production systems (poultry, beef, and swine), current production, storage, and disposal techniques present a challenge to manage wastes to minimize the emissions of trace gases within...
Impact of agriculture on water quality in the North Carolina Middle Coastal Plain
January 1, 2006By Michael D. Dukes
Water quality in the Middle Coastal Plain of North Carolina has been impacted by agriculture; however, the water quality impacts in these areas over time have not been studied in detail. The surface...
Review of the use of aerobic thermophilic bioprocesses for the treatment of swine waste
January 1, 2006By Pierre Juteau
For 40 years, aerobic thermophilic (AT) processes have been presented as a possible way of treating liquid manure, especially swine wastes. If they are well designed, bioreactors can be self-heating...
Characterization of volatile organic compounds and odorants associated with swine barn particulate matter using solid-phase microextraction and gas chromatography-mass spectrometry-olfactometry
January 1, 2006By Jacek A. Koziel
Swine operations can affect air quality by emissions of odor, volatile organic compounds (VOCs) and other gases, and particulate matter (PM). Particulate matter has been proposed to be an important...
Response of selected soil physical and hydrologic properties to manure amendment rates, levels, and types
January 1, 2006By Fares
Manure amendments affect several soil physical and hydrologic properties. The objectives of this study were to evaluate the effect of (i) manure amendment rates (0, 168, 336, and 672 kg total N...
