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...

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...

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...

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...

November 15, 2006By Peter Davies
Regional spread of PRRS and other swine diseases continues to place a major burden on North American swine producers. Advances in computers and communications technology are creating new...
Developing a Decision Support Tool to Optimize Swine Production Facility Layout to Minimize Downwind Air Quality Impacts
November 13, 2006
One of the most significant and persistent environmental concerns regarding swine production is the transport of odor constituents (e.g. ammonia and hydrogen sulfide), trace gases (e.g. greenhouse...

Analysis of periparturient factors affecting sow longevity in breeding herds
November 13, 2006By John Deen
The purpose of this study of this was to examine the effect of periparturient sow factors on the longevity of sows. This study followed sows from time of entry into the farrowing crate until a...

Analyzing PRRS status of piglets on multiple farms after serum exposure to validate production of negative piglets
November 3, 2006By Jeff Feder
Based on these results, serum exposure can be an effective way of stabilizing a sow herd and weaning negative piglets on a consistent basis in large, commercial sow units faced with a variety of PRRS...
