Compositional and functional features of humic acids from organic amendments and amended soils in Minnesota, USA
January 1, 2007
The use of organic amendments requires an adequate control of the chemical quality of their humic acid (HA)-like fractions and of the effects that these materials may have on the status, quality,...
Influence of slope position and hog manure injection on fall soil P and N distribution in an undulating landscape
January 1, 2007By Sumith K. R. Priyashantha
Investigation of how soil nutrients are distributed over the landscape in the fall is a prerequisite to identify critical source areas (CSA), which contribute soil nutrients to surface waters through...

How does drinking behavior influence feed intake and the development of behavior problems in newly weaned piglets?
December 29, 2006By Tina Widowski
Drinker style affects multiple aspects of production and behavior of the newly weaned piglet. Nipple drinkers contribute to high levels of water wastage, regardless of weaning age. Float bowl...

Influence of corn co-products on air emissions and nutrient excretionsfrom grow-finish swine
December 12, 2006By Wendy Powers
Corn co-products are an increasingly important alternative to corn in swine diets. While there has been some research to evaluate how these co-products affect pig performance, the effect on air...
Influence of corn co-products on air emissions and nutrient excretions from grow-finish swine
December 12, 2006By Wendy Powers
Four diets were fed to growing swine in order to compare corn (C) to corn co-products and the impact on swine performance and air emissions. The corn co-product diets contained increasing levels of...

Partitioning between pit and wall emission streams of hydrogen sulfide, ammonia, particulate matter, and odor from deep-pit pig finishing facilities for decision support in selecting emission control technologies
December 1, 2006By Larry D. Jacobson
The results of this study show limited benefit to exhausting a portion of air through the pit rather than through the wall for deep-pit pig finishing barns. This conclusion comes from similar indoor...
Swine Health - PRRS
Investigation into the ability of the anti-idiotype to block PRRS virus infection and characterization of a putative receptor on MARC-145 cells and porcine alveolar macrophages
November 25, 2006By Jeffrey Zimmerman
PRRS is the most costly disease U.S. swine producers confront and little progress has been made in recent years to improve the situation. Prevention and control of PRRS has been difficult, in part...

Developing a Decision Support Tool to Optimize Swine Production Facility Layout to Minimize Downwind Air Quality Impacts
November 13, 2006By Thomas J. Sauer
These model experiments of air flow characteristics suggest that when swine confinement buildings are oriented so that the approaching wind is parallel to the buildings the wind is reduced less than...

Development of a universal and differential serodiagnostic test for SIV
November 13, 2006By Kyoung-Jin Yoon
Swine influenza continues to be an economically significant respiratory disease in pigs of all ages. Serological testing is commonly employed to detect animals that have been exposed to swine...
