      Reproductive and Respiratory Syndrome virus infection - An analysis in the course 
      of a voluntary PRRSV control program in Saxony and Thuringia].

AB  - OBJECTIVE: In Saxony and Thuringia, federal states of Germany with a low density 
      of commercial pig farms, a voluntary program aims at controlling porcine 
      reproductive and respiratory syndrome virus (PRRSV) infection. This targets the 
      eradication of the infection on a herd level which has previously been achieved 
      in a subset of herds. The presented study aimed at identifying management factors 
      related with a positive or a negative PRRSV antibody (AB status) or PRRSV genome 
      status (PCR status) on a herd level. MATERIAL AND METHODS: Data were collected in 
      82 farms in a region implementing a voluntary PRRSV control program. The test 
      findings for the years 2011 to 2018 were compiled for each year and associated 
      with the interrogated parameters. A generalized linear mixed model was used to 
      identify factors associated with the AB and PCR status. RESULTS: The variables 
      "separation of contaminated and non-contaminated areas on the loading ramp" 
      (p = 0.012), "separation of gilts and sows" (p = 0.017) and "recording of 
      visitors in a book" (p = 0.046) were negatively associated with the PCR status. 
      In contrast, "separation of gilts and finishers" (p = 0.044) as well as the 
      existence of "separated alleyways" (p = 0.042) were positively related to the PCR 
      status. "Vaccination against PRRSV" was positively associated with the AB status 
      and the PCR status (p = 0.005 and p = 0.001, respectively). In numerous 
      variables, a low variability was observed. CONCLUSION: Certain biosecurity 
      measures to control the movement of animals (separation of contaminated and not 
      contaminated areas on the loading ramp) or people (recording of visitors) 
      contribute to a successful reduction of PRRSV infections and a negative herd 
      status. CLINICAL RELEVANCE: A combination of different measures may reduce PRRSV 
      spread within pig herds. Breaking the infection cycle in gilts, either by 
      separation of gilts from older sows or immunization, may be considered as a key 
      aspect, presumably additionally supported by keeping gilts together with 
      fattening pigs.
