Expanding the immune toolkit for assessing pig health and improving swine disease and vaccine studies
May 8, 2007By Joan K. Lunney
Swine disease and vaccine research will be advanced by the development of sophisticated tools to measure swine antibodies or immunoglobulins (Igs). Swine produce antibodies, or Igs, in response to...

Estimation of the mass balance of nutrients for specific production phases and the flow of nutrients through a swine farm
April 16, 2007By Scott Carter
Results from these experiments suggest that dietary manipulation can have dramatic effects on the mass balance of nutrients during the finishing phase. Altering the dietary crude protein and...

Development of cost-efficient herd testing protocols based on testing of pooled samples using ELISA
April 2, 2007By Claudia Munoz-Zanai
The objective of this study was to evaluate the feasibility of using pooled serum samples for detection of PRRSV-infected sow herds by ELISA. In order to achieve this objective, 113 true positive...
Evaluation of Boric Acid and Sodium Tetraborate to Reduce Ammonia and Hydrogen Sulfide Emissions from Swine Facilities
April 1, 2007
Borates have long been used in a number of commercial products for cleaning and controlling odors. However, they have not been examined for controlling hazardous gas emissions from stored livestock...

Use of naturally-occurring bacteriophage to reduce Salmonella in swine prior to harvest
March 27, 2007By Todd Callaway
Salmonella is one of the most common causes of foodborne illness in humans and can also impact swine production efficiency. Bacteriophage are viruses found in nature that can kill bacteria,...

Physical Characterization of the PRRSV Virion
March 23, 2007By Michael Murtaugh
The research here shows that PRRSV grows in cells as a population of viruses with the same shape, the same RNA molecules, and the same protein composition. There was no evidence for multiple forms...

Mechanisms of Failed Protection Against PRRS in Sow Herds
February 28, 2007By Michael Murtaugh
We have established a set of standard protocols and reagents for whole genome PRRSV sequencing and assembly. Phylogenetic comparisons amongst 10 pairs of homologous strains confirmed several regions...
