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

An Overview• Who’s involved• What are the desired outcomes• How is it going to be accomplished• Preliminary results• Preliminary observations
![Page 5: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/5.jpg)

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
![Page 7: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/7.jpg)
Desired Outcomes
• To Develop & Demonstrate a• Voluntary & Regional • BVDV Eradication/Control Model• In the USA
![Page 8: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/8.jpg)
“In the USA”• Other counties have “mandated” programs• Other states have voluntary control
programs• This is an “eradication/control” effort
![Page 9: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/9.jpg)
“Eradication/ Control Model”• We want the “model” to be repeatable or at
least• Have re-useable concepts• The model will be scientifically defendable
and • Balanced with user – friendliness (value)
![Page 10: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/10.jpg)
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
![Page 11: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/11.jpg)
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?
![Page 12: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/12.jpg)
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
![Page 13: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/13.jpg)
Communication is Critical! • What is going to happen• Who is doing what• What are the benefits• What are the costs• What happened• And repeat….

BVDV Education
![Page 15: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/15.jpg)
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
![Page 16: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/16.jpg)
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
![Page 17: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/17.jpg)
Testing• Farms Signed Up
– 168 Herds– Est. 13,006 Hd.
• Farms Testing – 140 Herds– 6,355 samples
• Deer Testing– 30 head
•
![Page 18: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/18.jpg)
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
![Page 19: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/19.jpg)
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
![Page 20: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/20.jpg)
Observation• “Eradication/Control” will take:
– Time– Effort– A Plan– Flexibility
![Page 21: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/21.jpg)
Observation• “Eradication/Control” is
– Testing herd negative
+ Bio-security (PI test & isolate)
+ Appropriate & PROPERLY DONE vaccination program
• And a Monitoring Program
![Page 22: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/22.jpg)
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
![Page 23: Michigan’s Upper Peninsula Bovine Viral Diarrhea Virus Eradication Project](https://reader030.vdocuments.net/reader030/viewer/2022032705/56649db05503460f94a9de9f/html5/thumbnails/23.jpg)
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
