With proper planning, this option could result in minimal downtime, if bred gilts are available. With adequate approval and safeguards to neighboring herds, growing-finishing hogs kept during cleaning and disinfection could be moved to a neighboring farm, or a separate, isolated feeding lot. Precautions must be taken to prevent recontamination of cleaned buildings by human, animal, or mechanical means. Sell sows as soon as pigs are weaned. Move pigs to a quarantined feedlot for finishing.
All disinfectants are less effective in the presence of organic matter.
Prevent wildlife and domestic animal exposure to swine and feed source. Wait 30 days after disinfection before repopulating. Wait longer if there is any question about effectiveness of cleanup and disinfection procedures. The period between cleanup-disinfection and repopulation can vary, depending on weather and individual farm conditions. Consider, along with the testing and retesting of animals used to repopulate, in the planning stage and make decisions after consultation with your veterinarian.
