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.
作者的报告对丹麦人工授精站的传染病控制情况进行了调查。该控制工作依据欧盟法规开展，要求在转入隔离区和人工授精站之前，有文件证明猪群无奥耶斯基氏病、经典猪瘟和布鲁氏菌病（基于血液检测）。报告还介绍了丹麦关于猪繁殖与呼吸综合征（PRRS）的法规，涉及血清学阳性和血清学阴性的站点。在一些站点，所有公猪都接种了针对美洲型PRRS（英特威PRRS疫苗）和欧洲型PRRS（普乐维美PRRS疫苗）的疫苗，随后PRRS血清学呈阳性。文中描述了从接种疫苗到精液可用的时间段，并解释了该时间段较长的原因。此外，还介绍了区分耶尔森氏菌与布鲁氏菌病反应时所采用的流程。这种控制的目的是防止供应公猪的耶尔森氏菌阳性猪群通过与布鲁氏菌病的交叉反应，影响来自耶尔森氏菌阴性猪群的供应。文中描述了转入隔离区和人工授精站之前所需的疫苗接种（猪传染性胸膜肺炎、副猪嗜血杆菌引起的胸膜肺炎、猪丹毒和猪细小病毒）以及人工授精站定期进行的疫苗接种（猪丹毒和猪细小病毒）。最后，报告介绍了丹麦人工授精站发现的其他疾病（主要是肺炎和腿部问题）及其治疗方法。
