PCV-2 viral DNA(s) are Infectious for Gnotobiotic Swine
January 23, 2004By Steven Krakowka
Porcine circovirus type 2 (PCV-2) infection is now recognized to be a common subclinical infection of swine of all ages. Disease expression as postweaning multisystemic wasting syndrome (PMWS) is...
Establishing Effects of application of Swine Manure on Crop Leaf Damage to Growing Crops
January 12, 2004By Charles Shapiro
Swine manure from a below barn storage facility was applied to growing corn
and soybeans to determine phytotoxic effects. The manure had an electrical
conductivity of around 20 mmhos/cm and was...

Well-Being of Early Weaned Piglets During Transport: Assessment of Seasonal Effects on Performance
January 5, 2004By Nora J. Lewis|Robert J. Berry
Impact of transport: Behavior during transport provides us with indicators of the immediate problems faced by piglets during transport and the coping strategies of the piglets. We can look at each...
Ammonia emissions from swine houses in the Southeastern United States
January 1, 2004
Ammonia (NH3) from confined animal feeding operations is emitted from several sources including lagoons, field applications, and houses. This paper presents studies that were conducted to evaluate...
Enzyme-linked immunosorbent assay for ultratrace determination of antibiotics in aqueous samples
January 1, 2004By K. Kumar
Two commercially available enzyme-linked immunosorbent assay (ELISA) kits that are commonly used for tylosin or tetracycline residues in meat and milk were adapted for ultratrace analysis of these...
Dust and odor emissions from tunnel ventilated swine buildings in North Carolina and comparison of different odor evaluation methods
January 1, 2004
Tunnel ventilation of swine buildings conveys odourous dust and gases out of the production buildings. Measurement of dust and odour levels and other environmental parameters is necessary for...
Seepage evaluation of older swine lagoons in North Carolina
January 1, 2004By Ronald L. Huffman
Thirty-four swine waste lagoon systems in North Carolina were examined for evidence of seepage losses to the shallow groundwater. All were constructed prior to the state's January 1993 adoption of...
Excretion of major odor-causing and acidifying compounds in response to dietary supplementation of chicory inulin in growing pigs
January 1, 2004
The excretion of major odor-causing and acidifying compounds in response to dietary supplementation of chicory inulin extract was investigated with six Yorkshire barrows, with an average initial BW...
Total and water-soluble phosphorus excretion from swine fed low-phytate soybeans
January 1, 2004
A study was conducted to evaluate the impact of feeding soybean meal (SBM) from low-phytate (LP) or traditional phytate (TP) soybeans on performance and excretions from growing swine. Ninety-six...
Kinetics of ammonia removal in a pilot-scale biofilter
January 1, 2004
A mobile, skid-mounted biofilter was designed and built to determine the kinetics of ammonia oxidation at a modern 2400-sow farrow-to-wean unit. The biofilter system consisted of a variable-speed...
