title: Management of disease control and epidemics in AI in Denmark.
abstract: The author's presentation constituted a survey of the control of contagious diseases at Danish AI stations. The control is performed in accordance with EU regulations and requires documented freedom from Aujeszky's disease, Classical Swine Fever and Brucellosis (based on blood testing) before transfer to quarantine sections and to AI stations. The Danish regulations regarding Porcine Reproductive and Respiratory Syndrome (PRRS) are described for both sero-positive and sero-negative stations. At some stations, all boars are vaccinated against both American PRRS (Ingelvac PRRS vet.) and European PRRS (Progressis vet.), and are subsequently sero-positive for PRRS. The period from vaccination until the time that semen can be used is described, and the reason for its length is explained. Furthermore, the process applied when distinguishing Yersinia from Brucellosis reactions is described. The purpose of this control is to prevent Yersinia-positive herds that supply boars from compromising supplies from Yersinia-negative herds through cross-reactions with Brucellosis. The vaccinations required before transfer to isolation and AI stations (Glasser's disease, pleuropneumonia caused by Actinobacillus pleuropneumoniae, erysipelas and PPV) as well as vaccinations done regularly at the AI stations (erysipelas and PPV) are described. Finally, a survey is presented of other diseases found at Danish AI stations (primarily pneumonia and leg problems) and their medical treatment.
