title: [Economic impact of Circovac® - vaccination in a PCV2 subclinically infected farm in Switzerland on performance parameters].
abstract: Vaccination of dams in a PCV2 subclinically infected farm 2 and 4 weeks before insemination, with a booster at 12 weeks of gestation did not influence fertility parameters of the dams. However, growth parameters of offspring of vaccinated sows improved significantly (+ 51 g/d), resulting in a shorter growing period of 9 days and a massively improved economy. Mortality of weaners and fattening pigs was not significantly influenced by dam vaccination. Nevertheless, compared to a period of 6 months before vaccination, the mortality rate declined in the weaning period by 0,3 % and in the fattening period by 5,5 %. The Return on Investment (ROI) was calculated with 1:9.5. Even, the historically low pork prices in 2011 led to a ROI of 1:7.
