Pork Safety - Pre-Harvest
Diagnosis and Prophylaxis of Clostridial Enteritides in Piglets
In a study entitled “The economic cost of major health challenges in large US swine production systems” (Holtkamp D et. al. AASV proceedings, 2007), Clostridium perfringens type A was...
Animal Science - Breeding & Genetics
Large-Scale Association Analyses of Candidate Genes for Feed Efficiency Traits in Pig
This study was conducted with the objectives of identifying genes which impact feed efficiency in pigs, quantifying those effects, and informing producers of how to utilize this information in...
Animal Science - Sow Lifetime Productivity
Association of genetic markers with structural soundness and its relationship to gilt development and sow longevity
Sow longevity or sow productive life (SPL) is an important complex trait for total profitability of pig production. Proper gilt development and selection are important means to reduce the culling and...
Animal Science - Breeding & Genetics
Large scale SNP association analyses of feed efficiency and longevity
Many traits financially important to hog producers are either expensive or time-consuming to measure or difficult to successfully select animals for based on low heritability of the targeted traits....
Swine Health - General Disease
Prevalence of slaughter house condemnation due to Erysipelothrix sp. and further characterization of isolates associated with these cases
The objective of this study was to confirm the presence and investigate the identity of Erysipelothrix spp. in condemned tissues obtained from a regional abattoir. Tissue specimens from 70 carcasses...

Identifying genes associated with Salmonella shedding to increase pork safety through improved genetic resistance
The long-term goals of this project are to use genomics tools to identify genetic variants that are associated with decreased Salmonella shedding on farms; and to use these variants to select for...
Swine Health - PRRS
Optimization of the PRRSV antibody ELISA for use in oral fluid-based surveillance
PRRSV, M. hyopneumoniae, influenza, PCV2, and other endemic pathogens continue to cause significant economic losses to U.S. swine producers. In part, the disease status quo is maintained by the...
Environment - Manure Storage / Application
Deep Pit Swine Facility Flash Fires and Explosions: Sources, Occurrences, Factors, and Management
Incidences of explosions and flash fires related to manure storage in deep pits were noted as early as 1969. Gases resulting from anaerobic decomposition of animal manure are the likely source of...
Public Health - Antibiotics & Resistance
Effects of Subtherapeutic Antibiotics on Antibiotic Resistance and Virulence Gene Transfer in Swine Intestinal Bacteria
Subtherapeutic antibiotics have been used for decades as growth promotants and prophylactic agents. The following antibiotics are approved for use a feed additives in swine: tetracyclines,...

Evaluation of the Effectiveness of the ISU Community Assessment Model in the Siting of Swine Production Units
It’s neither fun nor wise for rural communities to experience ongoing conflict related to odors from farming. The example of hog farming in Iowa provides a look at a conflict resolution tool...
