Infectious swine hepatitis E virus is present in pig manure storage facilities on United States farms, but evidence of water contamination is lacking
January 1, 2005By P. G. Halbur
Fresh feces, manure slurry (from earthen lagoons and/or concrete pits), and drinking and surface water samples were collected from 28 pig farms in the Midwestern United States. All samples were...
Sorption and desorption of ammonium from liquid swine waste in soils
January 1, 2005By K. Xia
Understanding the sorption and desorption behavior of NH4(+) in soils associated with animal waste is important because of the potential for the formation of NO3(-) and subsequent leaching that...
Multidimensional gas chromatography-olfactometry for the identification and prioritization of malodors from confined animal feeding operations
January 1, 2005By Donald W. Wright
Odor profiling efforts were directed at applying to high-density livestock operations some of the lessons learned in resolving past, highly diverse, odor-focused investigations in the consumer...
Soil extractable phosphorus changes with time after application of fertilizer: II. Manure from swine fed modified diets
January 1, 2005
Little is known about how diet modification and manure amendments affect extractable P in soils, which can be related to runoff P. The objectives of this study were to determine if there were any...
Effects of room ozonation on air quality and pig performance
January 1, 2005By Lingying Zhao
Reducing odor emissions from swine farms to avoid complaints about odor nuisance is a major issue. Ozonation has been used to reduce odor in swine buildings, but little research exists on its...
Phosphorous Transformation in Pig Slurry Due to Diet and Continuous Aeration Treatments
January 1, 2005By Samuel K. Baidoo
The experiment was conducted to study the transformation of phosphorus (P) in slurry from pigs fed two different diets, a regular corn soybean meal diet with or without supplementation of 40% ...
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...
