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...
Evaluation of electrolysis for oxidative deodorization of hog manure
January 1, 2005By Bunce|N.J.
Electrolysis was investigated as a method for the amelioration of odor from the supernatant phase of centrifuged liquid hog manure. Methods examined included the use of dual anodes to provide both...

Water intake and wastage at nipple drinkers by growing-finishing pigs
January 1, 2005By Y. Z. Li
Three experiments were conducted to assess water intake, water wastage, and a means to decrease water wastage by growing-finishing pigs from nipple drinkers. In Exp. 1, 48 pigs were studied during ...
Preliminary investigation of air bubbling and dietary sulfur reduction to mitigate hydrogen sulfide and odor from swine waste
January 1, 2005By Grant Clark
When livestock manure slurry is agitated, the sudden release of hydrogen sulfide (H2S) can raise concentrations to dangerous levels. Low-level air bubbling and dietary S reduction were evaluated as...
Dissimilatory iron reduction and odor indicator abatement by biofilm communities in swine manure microcosms
January 1, 2005By Bruns|M.A
Animal waste odors arising from products of anaerobic microbial metabolism create community relations problems for livestock producers. We investigated a novel approach to swine waste odor reduction:...
