Thermochemical Conversion Process to Produce Oil from Swine Manure
June 6, 2008By Yuanhui Zhang
Laboratory scale tests show that more than 60% of the volatile solids in swine manure can be converted to bio-crude oil using a thermo-chemical conversion (TCC) process. The process can work with...

Development of stable cell lines permissive for PRRSV replication and production
May 23, 2008By Dongwan Yoo
PRRS virus (PRRSV) infects only a specific line of simian cells in culture for productive infection. The use of these cells for vaccine development is patent-protected, which severely hampers the...

Macrolide, lincosamide, and streptogramin B (MLSB) resistance in soils amended with swine manure
February 1, 2007By Julie Zilles
The land application of treated swine manure has been proposed to contribute to the spread of antibiotic resistance, but this possibility has not been confirmed. In this work we measured antibiotics...

The frequency of the HAL-1843 mutation of the RYR gene in dead and non-ambulatory/non-injured pigs on arrival at the packing plant.
October 11, 2006By Michael Ellis
The HAL-1843 mutation of the RYR gene (commonly called the “Stress” or “Halothane” gene) is associated with increased stress susceptibility and death loss in pigs. Death loss and...

Critical Review of Functional Animal Proteins
July 26, 2006By James Pettigrew
Spray-dried plasma and immune egg products provide dramatic benefits when added to diets of young weaned pigs. Spray-dried plasma increases growth rate and resistance to enteric infection, while...
