Pennsylvania Swine Disease Control Program

Meghann Pierdon, VMD

PA Project History• Statewide program in existence for over 10 years• Started with negative areas and goals of maintaining and

expanding• ARC coordinator started in 2012– Updated database- VERY IMPORTANT– Know the politics to get everyone included– Covers over 90% of the pigs in Pennsylvania– Started using Basecamp for information sharing

GDU 10 23315Boar Stud 4 630

Total 544 1.27 Million

*Soon we will have ~65 Niman Ranch Sites included in the database due to a coordinated sign-up effort

• Participants– 22 Companies from 4 sites to 165 sites– 50 independent producers

PA Project Goals• Regional control zones

– Goal is to be PRRS and PED negative in these zones

– Chosen for high numbers of multiplication animals or sow units

• 3 mile buffer zones– Goal is to decrease the PRRS and

PED positive pigs in the 3 miles around sows, boars and gilts to zero

– Had gotten to only a few positive sites in a 2 mile radius so expanded to 3 miles

Metric: PRRS Status in 3 mile BuffersPreviously at 7% with the 2 mile buffers

Currently at 10% in the 2 mile buffers

PA Information Flow and Frequency• Disease breaks - Sent out by herd veterinarians• Monthly Updates compiled and sent out by

coordinator– PRRS Status changes– PRRS trends over time– List of PED positive sites– PED trends over time– Sent To:

• 75 email addresses• 12 fax machines• Quarterly mailings to about 15 people

– Starting to report strain information• Quarterly Map updates

PA Example: Monthly PED Reports

PA project take home• Producer engagement is high and the reason for success

– Examples:• Map is down for maintenance and I get emails asking why they can

not get access to the map• Every company got a list of all their finishers and how close they are

to sows, gilts and boars– Emails from people saying they “loved” the list– Used during the last two PRRS breaks by companies placing their pigs

• They were not content to stop with the 2 mile radius and wanted to keep expanding

NC IL ARC Project

Carrie Pollard, M.S.Technical Services Manager

Bethany Swine Health Services

NC IL Project History• Began winter of 2009-2010• ~20,000 sows in the area changing genetics– PRRS-negative breeding stock

• Massive changes early• Slow, sideways movement currently• PEDv provided positive motivation

• Our break rate was 30% vs. national average >40%

NC IL Participants

• ~80 sites– 1/3 sows, 2/3 finishing

• ~45 producers– Mostly independents,

though 90% is associated either via pig flow or veterinary relationship with Bethany Swine

NC IL Project Goals• Goal: Stabilize, Control, Eliminate PRRS

– Improve production• Sow farm• WTF

– Communication• Prevent reinfection• Decrease new strain introduction

– Learn• Prevention• Intervention

NC IL: Sow herd vaccination rate

NC IL Information flow and frequency

• Routine PRRS Status & Sequence Information– Maps are made (& largely ignored)– Difficult to read & interpret

• Outbreak Alerts

NC IL project take home• ARC’s are: Long-Term and Adaptable – This is a marathon NOT a sprint– Motivation is more difficult as you pick off the low-hanging

fruitBUT– We have moved the needle– We have changed the mindset

• Better prepared for PEDv & whatever comes next

South East Iowa ARC Project

Sonya Maas

SE IA Project History• Started in 2010 by small group of neighbors in an attempt to protect their own sow

farms.

• Today - 54 Producers (both large systems and small independent producers) from South East Iowa working together to “control” PRRSv, PEDv and other regional diseases– 449 sites enrolled (1,000,000+ pigs)

• Local and regional consulting herd veterinarians

• Sequencing & mapping support from BIVI – 600+ sequences in project database

– Pilot project for ARC concept, Disease BioPortal and SAHDD connection to BioPortal

Only producers with signed consent forms were included

SE IA Project Goals• Increase awareness of PRRSv, PEDv, and other disease and

their associated costs• Reduce incidence & severity of regional diseases, such as

PRRSv and PEDv– Fewer introductions of new highly pathogenic strains of PRRSv

– Decrease length of time of PRRSv shedding

– Improve biosecurity

– More consistent sow farm and grow finish production

• Study movement of regional diseases

Herd vet or producer: Change in status (Barn fill, lab results, vaccination,

herd stabilization, etc.)

Coordinator: Summary of status

changes and creation of Bulletin and maps.

Distribution to participants via

BaseCamp (e-mail)

SE IA Information flow and frequency• Bi-weekly project status updates

• Other Information:– Sequence requests and results – as arise

• Herd Veterinarian/Producer to Project Coordinator/BIVI reported back to Vets– New site enrollment – as rise

• Herd Veterinarian/Producer to Project Coordinator– Herd Outbreaks – as arise

• Herd Veterinarian/Producer to Project Coordinator to Working Group– Meeting requests, educational tools, issues/concerns – as arise

• Project Coordinator to Working Group

SE IA take homeOur local producers and veterinarians have taken ownership of the program and are committed to protecting their herds through participation in the project.

We have a long way to go to keep PRRSv under control in the area, but the group is driven to achieve our goals based on the results and accomplishments they’ve seen in the last 5 years.

Project HistorySW IA ARC

• Spring 2013• With it being a relatively low

risk area we wanted to work together to monitor PRRS movement and maintain a negative PRRS status in GDU/Sow/Boar sites within the ARC area.

NE IA/SE MN ARC• August 2013• With it being a relatively low risk

area we wanted to work together to monitor PRRS movement within the ARC area.

• The larger producers in the area got involved right away and we are currently seeking out the independent producers in the area.

SW IA Participants

• 224 Sites– 73 Wean to Finish– 12 Nursery– 60 Finishing– 39 GDU– 35 Sow– 5 Boar

• 8 Active Companies

NE IA/SE MN Participants

• 159 Sites– 28 Wean to Finish– 18 Nursery– 96 Finishing– 5 GDU– 12 Sow

• 6 Active Companies

Project GoalsSW IA ARC

• Understand PRRS risk from neighboring sites

• Mitigate PRRS transmission between sites in the area

• Share sequences to differentiate new PRRS introductions into the ARC area from area spread of existing viruses.

NE IA/SE MN ARC• Understand PRRS risk from

neighboring sites• Mitigate PRRS transmission between

sites in the area• Share sequences to differentiate new

PRRS introductions into the ARC area from area spread of existing viruses.

• Gain a better understanding of the viral circulation in the area.

Information Flow• Currently both groups are only sharing PRRS status.

– Monthly Status Update• Reminder Email BioPortal Update Basecamp Notification of

Updated Maps• The monthly reminder is mainly for finishing changes.

– Outbreak alerts• If there are any major issues, such as a PRRS break at a sow farm,

GDU, or Boar stud within the ARC, I am notified and relay the message on to the group.

SW IA and NE IA/SE MNtake homes

• Teamwork:– A sow farm in an otherwise PRRS stable area broke with

a new PRRS virus and had no way to get positive weaned pigs out of the area.

– Another participant offered up a site to move the wean pigs outside the ARC area.

– This is an example of successful teamwork with the same end goal in mind-PRRS stabilization.

Quick Synopsis

Click to edit Master• Each ARC Project is unique

– Make up of participants– Goals and objectives– Communication style and frequency

• What defines a successful project?– Producer involvement– Fewer Positive sites in sow/GDU/Boar buffers– Fewer new emerging strains in the area– Teamwork and information sharing
