Abstract
Using a partial sanitation method "Enzootic Pneumonia" (EP) could be eradicated in 17 EP-reinfected pig breeding herds. Partial sanitation includes separation measures in form of a piglet and gilt free interval on one side and as an additional protection against reinfection the temporary feeding of a medicated diet on the other side. Frequent herd controls for several years as well as mixed fattening experiments with carcass examination combined with milk and blood serology served as criteria for the sanitation success. From these results it is concluded that the infection pathway of EP is mainly maintained by young animals in the herd. Contrary to total sanitation, which will amount to at least sFr. 720 per sow, partial sanitation will only cost between sFr. 40-170 per sow, depending on herd size. Therefore, partial sanitation may be regarded as a full alternative to total sanitation after an outbreak of EP.
