Manipulation of dietary protein and nonstarch polysaccharide to control swine manure emissions
January 1, 2005
Odor and greenhouse gas (GHG) emissions from stored pig (Sus scrofa) manure were monitored for response to changes in the crude protein level (168 or 139 g kg-1, as-fed basis) and nonstarch...
Role of internal nutrient storage in duckweed growth for swine wastewater treatment
January 1, 2005
The objective of this study was to investigate the relationship of the nutrient content of duck-weed biomass to duck-weed growth in swine wastewater. Batch tests of Spirodela punctata 7776, the...
Size distribution and composition of particles in raw and anaerobically digested swine manure
January 1, 2005
The design of efficient manure treatment systems requires a better characterization of particle and nutrient distribution in manure slurries. The aim of this project was to study particle size, COD,...
Assessment of an aerosol treatment to improve air quality in a swine concentrated animal feeding operation (CAFO)
January 1, 2005By Timothy J. Buckley
Poor air quality within swine concentrated animal feeding operations (CAFOs) poses a threat to workers, the surrounding community, and farm production. Accordingly, the current study was conducted to...
Field-scale evaluation of phosphorus leaching in acid sandy soils receiving swine waste
January 1, 2005By Nathan O. Nelson
Accurate descriptions of P leaching are important because excess P applied to soils can enter surface water via leaching and subsurface transport, thereby negatively impacting water quality. The...
Deodorization of swine manure using minced horseradish roots and peroxides
January 1, 2005By Jerzy Dec
Public concerns about offensive odors from livestock manures are on the rise and so is the pressure to develop practical ways to reduce the odors. The use of minced horseradish (Armoracia rusticana...
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...

The Effect of Space Allowance and Season on the Welfare of Early Weaned Piglets Under Commercial and Expermental transport conditions
December 13, 2004By Nora J. Lewis|S. Wamnes
Early weaning is a stressful period as reflected by high serum cortisol levels. Transport can add to this stress. In winter, cold environmental temperatures result in cold truck temperatures, lower...

A novel PRRS vaccine in a bacterial vector known to stimulate strong cell-mediated and humoral immunity
November 5, 2004By MVSc|PhD|Ramesh Vemulapalli BVSc&AH
The results of this research project suggest that, despite several unique, advantageous properties, Brucella abortus RB51 is not very useful for developing effective recombinant PRRS vaccines.
