Research & Knowledge Management
Prioritization of AR’s
• NCBA AR- High Priority
Research & Knowledge Management
Research Update
Dr. Mohammad Koohmaraie
• Cow plant study
– Variable pathogen prevalence on hides
– Interventions are effective = 0 positives in hot box
• Feedlot Study
– E. coli O157:H7 prevalence variable across pens
– Some animals never shed the pathogen
– All animals must be sampled to account for variation
• Transportation and Lairage
– Hide prevalence higher at plant
– 70% of isolates of unknown origin
• Enumeration methodology
– E. coli and Salmonella = $2 per sample
• E. coli survival on hides
– @ 9 days
Research & Knowledge Management
Research Update
Dr. Rod Moxley
• Vaccination effects on E. coli O157:H7
prevalence
– 2 doses- entry and re-implant
– Harvested 85 days after 2nd vaccination
– Fecal samples= vaccinated cattle 62% less
likely to shed vs. unvaccinated
– Vaccinated cattle 54% less likely to have hide
contamination
