2. Outline Current PRRS Control Difficulties
Overview of New Technologies
Benefits in improving PRRS control
Best practices in evaluating “tools”
3. Current PRRS Control Difficulties (I) Herd Exposure and Closure Program works, but
Difficult to remain “negative” without re-infection
Cost of closure period
Cost of repeated closure (parity shift, logistics)
Periodic “leaking” from large herds
Impact on Wean-Finish performance
Managing multiple flows
4. Current PRRS Control Difficulties (II) Multi-strain Acclimation
Difficult to manage
Difficult to measure / monitor
Re-infection, Lateral Infections,
Finishing ? Sow or System ? System
Strain variation; Density ; Naďve populations
5. Overview of New Technologies MJPRRS® Grouping Technology for differentiating PRRS viruses to improve programs for control.
MJPRRS® Vaccine Technology for manufacturing of killed PRRS virus vaccine to improve antigen presentation.
6. Smart Strain Selection™ Services

D, S, and E main groups x each 8 subgroups
7. PRRS Isolate “demographics”
8. Optimized level of ORF5 antigen extracts
Enriched PRRSv protein components
Enhanced Glycosylation dynamics
U.S. Patent #7,776,537 / Foreign Patent pending
9. MJPRRS® Vaccine Production Process
10. Benefits resulting from these new technologies? MJPRRS® Vaccine Rapid control of “leaking PRRS virus”
Shortened interval to negative pigs after infection
Improved acclimation process (gilts)
Improved herd exposure-closure process
Improved response to new virus infections
Safer than LVI
11. Strategies with MJPRRS® Vaccine For a tool in herd exposure and closure projects
? Incorporate MJPRRS® Vaccine with knowledge of the FARM and AREA specific PRRS strains.
For improving maternal immunity for piglets
? Incorporate MJPRRS® Vaccine at 11 weeks and 3 weeks pre-farrow
For a tool for gilt acclimation
? Incorporate MLV + MJPRRS® Vaccine
12. Critical Messages MJPRRS® Vaccine is not intended to be used in naďve animals as a replacement for MLV / Serum.
MJPRRS® Vaccine does allow homologous and heterologous vaccination, simultaneously.
Evaluation steps can be initiated with vet-to-vet collaboration.
Increased sow herd protection for less than 50 cents per pig weaned.
13. It makes you think about what will be the
standards applied to PRRS control in
these areas:
Sow Herd Stabilization
Replacement Gilt Acclimation
Piglet Protection
Area Control
