National Hog Farmer April 2012 Blueprint Issue
Porcine reproductive and respiratory syndrome (PRRS) remains the pork industry's most difficult animal health challenge and by far the most costly endeavor that producers have ever had to deal with. To help producers manage this ongoing problem, this special edition of the National Hog Farmer Blueprint Series is devoted to PRRS. Articles detail the lengthy history of the virus and the triumphs and tragedies that have marked this decades-long battle. This Blueprint issue also offers information on the science of biosecurity, air filtration programs geared to sow farms, a biosecurity checklist for sow farms that can't filter and cleanup programs that provide the best payback.
