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...
Piggery slurry composting using batch operating autothermal thermophilic aerobic digestion system
January 1, 2006
The performance of an autothermal thermopholic aerobic digestion (ATAD) system was studied to determine if nitrogen loss, as ammonia, was affected by an exhaust gas condenser. The system was run with...
Soil Nutrient Dynamics from Swine Effluent Application to Common Bermudagrass Overseeded with Cool-Season Annuals
January 1, 2006By K. R. Sistani
A 3-year study was conducted to investigate the major nutrient dynamics in soil receiving swine effluent as the sole source of plant nutrients for warm-season perennial bermudagrass and cool-season...
Modification and Validation of GLEAMS for Prediction of Phosphorus Leaching in Waste-Amended Soils
January 1, 2006By R.D. Kinley
Excess phosphorus applied to soils with low P adsorption capacities can enter surface water via leaching and subsurface transport, thereby negatively impacting water quality. Computer simulation...
Development of a hydrophilic interaction chromatography-mass spectrometry assay for spectinomycin and lincomycin in liquid hog manure supernatant and run-off from cropland
January 1, 2006
A specific and sensitive analytical method was developed to extract and quantify spectinomycin and lincomycin in liquid hog manure supernatant and simulated rainfall run-off from manure-treated...

Free fatty acids and sterols in swine manure
January 1, 2006By Loughrin
Free fatty acids and sterols were assessed in fresh manure and anaerobic lagoon sludge from swine production facilities in North Carolina. Eight free fatty acids and five sterols were identified and...
Winter Cover Crop and Management Effects on Summer and Annual Nutrient Yields
January 1, 2006By D.E. Rowe|T.E. Fairbrother
Effluent from a swine (Sus scrofa domesticus) lagoon is often applied repeatedly to nearby fields because of logistical constraints and costs of transportation. To minimize accumulation of soil...
Small livestock producers with diffuse water pollutants: adopting a disincentive for unacceptable manure application practices
January 1, 2006By Centner
The problem of water pollution from small livestock producers (non-concentrated animal feeding operations) could be addressed through water quality regulations that apply to additional livestock...
Disinfection of swine wastewater using chlorine, ultraviolet light and ozone
January 1, 2006By Macauley
Veterinary antibiotics are widely used at concentrated animal feeding operations (CAFOs)
to prevent disease and promote growth of livestock. However, the majority of antibiotics
are excreted from...
Antimicrobial Use and Resistance in Swine Waste Treatment Systems
January 1, 2006By Julie L. Zilles
Chlortetracycline and the macrolide tylosin were identified as commonly used antimicrobials for growth promotion and prophylaxis in swine production. Resistance to these antimicrobials was measured...
