Implementation of a PRRS control programme should be an active communication process involving all individuals who will be affected by the plan or potential change.
The key to successful implementation is a communication plan that incorporates:
Programme monitoring has two components:
Example of sampling-testing protocol for PRRSV regular surveillance
|Herd type||PRRS status (AASV)||Age of pigs / frequency||Sample type||Number of samples||Diagnostics test|
|Breeding (farrow-to-wean)||Negative (IV)||Adults / quarterly||Serum||10 - 30||ELISA|
|Weaning-age piglets / monthly||Serum||30 - 60||PCR and sequencing|
|Breeding (farrow-to-finish)||Negative(IV)||Adults / quarterly||Serum||10 - 30||ELISA|
|Positive Unstable(I) or Positive Stable(II)||6- to 10- week-old-pigs / monthly and / or 16- to 20-week-old pigs / monthly||Oral fluids||1-4 ropes / 1000 pigs||PCR and sequencing|
|Nursery or finisher||Negative||4 weeks post placement in nursery and finishing for all- in / all-out quarterly for continous flow sites||Serum||10 - 30||ELISA|
|Oral fluid||1-4 ropes / 1000 pigs||PCR and sequencing|
|Positive||4 weeks post placement in nursery and finishing for all- in / all-out or quarterly for continous flows sites||Serum||10 - 30||ELISA|
|Oral fluid||1-4 ropes/1000 pigs||PCR and sequencing|
