  39. 39. CONCLUSIONIn farm “Brashlen” CIRCOVAC: increases the reproductive performances – number of live born piglets + 3.1 and + 1 weaned pig/litter increases the kg produced by sow
  40. 40. CONCLUSIONIn farm “Brashlen” CIRCOVAC : improves the pig growth from birth to slaughter + 41 g ; + 77 g reduces the duration to 100 kg – 5,3 days helps for homogenous pig batches restore mortality rate prevent from appearance of stomach ulcers
  41. 41. CONCLUSION CIRCOVAC helps the farm “Brashlen” to have a good profit at the difficult time with a lots of crisis…and welfare requirements… CIRCOVAC regular sow + piglet vaccination is an investment in that farm with 2700 sows and a lots of piglets…
  42. 42. CONCLUSION …but ROI are justified already more than 3 years and prove definitely that the sow + piglet vaccination gives the best performance in farrow- to-finish farm.
