  • NB! Farm was an attempt to make vaccination of pigs later (at 60 days and after) to solve the problem of PCV2 which manifested itself later (in fattening). It gave no result.

  • * In the mass vaccination some sows received 1, some 2 and some 3 vaccines
  • * In the mass vaccination some sows received 1, some 2 and some 3 vaccines
  • From 2008 the changes in management were pointed to increase the results as they were less than DanBred. As soon as the results start to improve this cause stress and clinical PCV2 problems. Firstly they observe them in fatteners and a little later in reproduction.

    12. 12. Vaccination protocol - boars : Parvovirosis +Erysipelas 6 months Parvovirosis +Erysipelas
    13. 13. Vaccination against PCV2 - WHY? <ul><li>Increased % ” lightweight ” pigs , especially </li></ul><ul><li>in fattening period </li></ul><ul><li>Mortality rate - slight increase in fatteners (2%) </li></ul><ul><li>Single cases of PDNS </li></ul>

    15. 15. First choice - CIRCOVAC on piglets - WHY? <ul><li>Farm performance before vaccination </li></ul><ul><li>No visible reproductive disorders </li></ul><ul><li>Farrowing Rate >90% </li></ul><ul><li>ADWG in growers – 0,566 kg </li></ul><ul><li>ADWG in fatteners – 0,983 kg </li></ul>
