In einem Teil der Betriebe verlief diese bereits erfolgreich. Ziel dieser Studie war, Managementfaktoren zu identifizieren, die mit einem positiven bzw. negativen Status bez\u00fcglich des Nachweises von PRRSV-Antik\u00f6rpern (AK-Status) oder PRRSV-Genom (PCR-Status) auf Herdenebene in Beziehung stehen.<\/jats:p><jats:p>Material und Methoden Die Datenerhebung erfolgte in 82\u2005Betrieben einer sich in Sanierung befindlichen Region. Befunde von Untersuchungen der Jahre 2011 bis 2018 wurden jahresweise zusammengefasst und zu den abgefragten Parametern in Zusammenhang gesetzt. Ein generalisiertes lineares gemischtes Modell wurde verwendet, um mit dem AK- und PCR-Status assoziierte Faktoren zu identifizieren.<\/jats:p><jats:p>Ergebnisse Eine negative Beziehung zum PCR-Status bestand zu den Variablen \u201eSchwarz-Wei\u00df-Trennung auf der Laderampe\u201c (p\u2005=\u20050,012), \u201eTrennung von Jungsauen und Sauen\u201c (p\u2005=\u20050,017) sowie \u201eF\u00fchren eines Besucherbuchs\u201c (p\u2005=\u20050,046). Dagegen waren die Variablen \u201eTrennung von Jungsauen und Masttieren\u201c (p\u2005=\u20050,044) und \u201egetrennte Treibwege\u201c (p\u2005=\u20050,042) positiv mit dem PCR-Status assoziiert. Die Durchf\u00fchrung einer PRRSV-Impfung stand in positiver Beziehung mit dem AK- und dem PCR-Status der Betriebe (p\u2005=\u20050,005 bzw. 0,001). Innerhalb zahlreicher Variablen wurde eine geringe Variabilit\u00e4t beobachtet.<\/jats:p><jats:p>Schlussfolgerung Bestimmte Biosicherheitsma\u00dfnahmen zur Regulierung des Tierverkehrs (Schwarz-Wei\u00df-Trennung auf der Laderampe) oder Personenverkehrs (Besucherbuch) sowie das Management der Jungsauen tragen zu einer Reduktion von PRRSV-Infektionen und damit zu einem negativen Bestandsstatus bei.<\/jats:p><jats:p>Klinische Relevanz Durch eine Kombination verschiedener Ma\u00dfnahmen kann die Ausbreitung von PRRSV in Schweinebest\u00e4nden reduziert werden. Schwerpunkt ist dabei die Unterbrechung von Infektionsketten bei den Jungsauen, entweder durch eine von Altsauen separierte Eingliederung oder Immunisierung, wozu m\u00f6glicherweise auch eine gemeinsame Haltung mit Mastschweinen beitragen kann.<\/jats:p>","DOI":"10.1055\/a-1308-6445","type":"journal-article","created":{"date-parts":[[2021,2,16]],"date-time":"2021-02-16T14:53:10Z","timestamp":1613487190000},"page":"30-39","source":"Crossref","is-referenced-by-count":1,"title":["Beziehungen
