Farm performance before vaccination
No visible reproductive disorders
Farrowing Rate >90%
ADWG in growers – 0.566 kg
ADWG in fatteners – 0.983 kg
Stoykov et al. (2011), APVS, Pattaya, Thailand

17. Vaccination against PCV2 - Why?
Farm performance before
vaccination
Increased %
”lightweight” pigs,
especially in fattening
period
Mortality rate - slight
increase in fatteners
(2%)
Single cases of PDNS

18. Vaccination against PCV2 - Why?
Farm performance before vaccination
Necropsy – stomach ulcers
Performance lower than top DanBred farms
Positive PCV2 serology
SUB CLINICAL PCVD

19. No changes meantime
Same genetic
Same feed
Same vaccination program
(except CIRCOVAC)
Same biosecurity
… but the farm is live organism…

vaccination - PROTOCOL
All pigs at age 29-100 days
Single injection - 0,5 ml, IM

21. CIRCOVAC - Piglet REGULAR
vaccination - PROTOCOL

25. After good piglet results – sow
vaccination – WHY?
A lot of confirmations of
influence of PCV2 on
reproduction

26. After good piglet results – sow
vaccination – WHY?
• Very good
farrowing rate…
…but opportunity to
reach better results in
number of
born/weaned piglets

27. CIRCOVAC – Reproduction herd
MASS vaccination - PROTOCOL
Sows, gilts, boars
Start – end of July 2009

*in mass vaccination some animals received 1 injection, another - 2
and other -3

28. CIRCOVAC – Sow REGULAR
vaccination - PROTOCOL
One injection at each gestation at least
2 weeks before farrowing
Dose – 2 ml, IM

39. CONCLUSION
In 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. CONCLUSION
In 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. 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. 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.

43. THANK YOU !
