  1. Michigan’s Upper PeninsulaBovine Viral Diarrhea Virus Eradication Project

  2. Lake Superior Wisconsin Lake Michigan

  3. Michigan’s Upper Peninsula • Mixture of approximately • 13,000 dairy cows – 100 farms • 10,000 beef cows – estimate 700+ farms • Spread over 15 counties in “pockets” of ag. • The UP is about 350 miles W to E 150 miles N to S

  4. An Overview • Who’s involved • What are the desired outcomes • How is it going to be accomplished • Preliminary results • Preliminary observations

  5. Who’s Involved? • UP Beef and Dairy Producers • UP Livestock Industry Services • Veterinarians, MDA, USDA • Michigan State University • College of Veterinary Medicine • MSU Extension • Diagnostic Center for Population and Animal Health • Pfizer Animal Health

  6. Who’s Involved..Infra-structure support personal • Producer ID and Educational Activities • producer lists management, mailing letters, • Sample Shipping and Handling • Extension offices & local veterinary clinics • Laboratory Data Handling • Data management • Peer Influence of Producers • Critical motivational consideration

  7. Desired Outcomes • To Develop & Demonstrate a • Voluntary & Regional • BVDV Eradication/Control Model • In the USA

  8. “In the USA” • Other counties have “mandated” programs • Other states have voluntary control programs • This is an “eradication/control” effort

  9. “Eradication/ Control Model” • We want the “model” to be repeatableor at least • Have re-useable concepts • The model will be scientifically defendable and • Balanced with user – friendliness (value)

  10. Voluntary and Regional • Program is Voluntary but we want 100% of cattle operations to participate • UP has many small and youth “herds” • Is (1) 4-H steer a “herd”? • Program is for Entire Region • Not just a regional effort

  11. To Develop and Demonstrate • How do you ID cattle herds? • How do you carry out testing? producer ear notching vs veterinary sampling • How do you keep tract of test results? • What happens after herd “tested negative” • How to verify that what you did, worked? • How to take theory into reality?

  12. The program in Year 1 • Program roll out and education • Use of meetings & monthly newsletter • Divide UP in to 3 regions for 3 years • Western – Eastern – Central • Plus “volunteer” herds • “Sign up” at central locations • Contact individual producers

  13. Communication is Critical! • What is going to happen • Who is doing what • What are the benefits • What are the costs • What happened • And repeat….

  14. BVDV Education

  15. Year 1 .. continued • UP region wide UP State Fair required all cattle to BVD-PI test negative • Purebred beef sale required BVD-PI test • Planning for Year 2 • Eastern UP Sign up • Survey system to validate herds are negative • Verification of survey system

  16. Year One - Results • Year 1 • Focus on Western UP • Approx. 98 herds • 67 Beef & 11 Dairy = 80% sign up • Plus Volunteer Herds • 65 Beef & 25 Dairy

  17. Testing • Farms Signed Up • 168 Herds • Est. 13,006 Hd. • Farms Testing • 140 Herds • 6,355 samples • Deer Testing • 30 head

  18. Testing Results • Positive Farms 4 (2.86%) • Number of PI’s 8 (0.13%) • 2 farms with 1 PI • 1 farm with 2 PIs • 1 farm with 4 PIs -All PIs were calves - 1 to 4 months -All calves put down - No indemnity - 2 deer were sero-positive

  19. Preliminary Observations • “Eradication/Control” is as much about people as it is about disease • Communication is HUGE • Pivotal in Voluntary Program • Important anytime / all the time

  20. Observation • “Eradication/Control” will take: • Time • Effort • A Plan • Flexibility

  21. Observation • “Eradication/Control” is • Testing herd negative + Bio-security (PI test & isolate) + Appropriate & PROPERLY DONE vaccination program • And a Monitoring Program

  22. Unintended Consequences • BVD with PI’s is a great disease for teaching bio-security • We have identified a great gap between a herd being “vaccinated” and an appropriate and properly applied “vaccination program” • Producers becoming very well versed in practical disease management

  23. In Conclusion • Thank you Pfizer & MSU for support • Thank you to UP cattle producers • Patience & Participation • Thank you to You- for opportunity to share program

  24. QUESTIONS?

  25. Progress • Program started December 2007

  26. Year 2 (2008/9) • Focus on North East UP • Year 3 (2009/10) • Focus on Central UP

  27. Industry Impacts • Tremendous Excitement • Industry Cooperation • BVDV Free Livestock Exhibits • Marketing of BVDV Free Cattle • New Appreciation For Biosecurity • New Focus Comprehensive Disease Control
