Assessment of Mycoplasma hyopneumoniae strain variability and relationship to virulence
February 26, 2004By F. Chris Minion
Mycoplasma hyopneumoniae isolated from different pig herds showed variation in disease potential. This is not unexpected since differences in disease symptoms occur widely in the field. There have...

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...
Characterization of VOCs and particulates from swine finishing facilities
January 1, 2004By Wendy Powers
Emissions from animal feeding operations have been a prominent topic in Iowa for a number of years,particularly during 2002. To address the issue a study was initiated to determine 1) if phase of...
Abatement of ammonia emissions from swine lagoons using polymer-enhanced solid-liquid separation
January 1, 2004By Ariel A. Szög
A study was conducted to determine the effects of solid-liquid separation of liquid swine manure on ammonia emissions from lagoons. This determination was done at full-scale in two contiguous swine...
Phosphorus Composition of Manure from Swine Fed Low-Phytate Grains: Evidence for Hydrolysis in the Animal
January 1, 2004By April B. Leytem
Including low-phytic-acid grains in swine diets can reduce P concentrations in manure, but the influence on manure P composition is relatively unknown. To address this we analyzed manure from swine...
