An efficient way to monitor the success of the program is to track diagnostic & pig performance data. Usually clinical parameters recover first, but PRRSv may be still present and circulate at low prevalence and can jeopardize the long term success of the control program.
Follow this practical decision tree, and remain on the right path.
For sow herds:
This straight forward decision tree, guides the monitoring plan to verify the outcomes of the implemented solutions.
For grow-finish herds:
Track progress on key performance indicators including survivability, average daily weight gain, feed efficiency and antibiotic use.
At the whole-system level (breed-to-market):
☐ Reduced wild-type incursions
(i.e., increase the interval between outbreaks).
☐ Reduced wild-type virus diversity
(i.e., less number of distinct strains).
☐ More herds at the Stable or Negative status
(i.e., less acutely infected or endemically infected).
☐ Better productivity!
