Vaccination against PCV2 - Why?

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

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

Vaccination against PCV2 - Why?

Farm performance before vaccination

Necropsy – stomach ulcers

Performance lower than top DanBred farms

Positive PCV2 serology

Vaccination against PCV2 - Why?

SUB CLINICAL PCVD

No changes meantime

Same genetic

Same feed

Same vaccination program (except CIRCOVAC)

Same biosecurity … but the farm is live organism…

CIRCOVAC - Piglet MASS vaccination - PROTOCOL

All pigs at age 29-100 days

Single injection - 0,5 ml, IM

CIRCOVAC - Piglet REGULAR vaccination - PROTOCOL

All pigs at weaning (28-29 days)

Single injection - 0,5 ml, IM

After good piglet results – sow vaccination – WHY?

A lot of confirmations of influence of PCV2 on

reproduction

• Very good

farrowing rate…

…but opportunity to reach better results in number of born/weaned piglets

After good piglet results – sow vaccination – WHY?

CIRCOVAC – Reproduction herd MASS vaccination - PROTOCOL

Sows, gilts, boars

Start – end of July 2009 Dose – 2 ml, IM, 2 injections, 3 weeks apart One further injection at least 2 weeks before farrowing *in mass vaccination some animals received 1 injection, another - 2 and other -3

CIRCOVAC – Sow REGULAR vaccination - PROTOCOL

One injection at each gestation at least 2 weeks before farrowing Dose – 2 ml, IM

CIRCOVAC – Gilts REGULAR vaccination - PROTOCOL

Primary vaccination:

Dose – 2 ml, IM, 2 injections, 3 weeks apart, second injection at least 2 weeks before mating Booster: One injection at least 2 weeks before farrowing

Gilts – Primary vaccination – 2 injection, 3 weeks apart, booster – 1 injection, 2 weeks before farowing

Piglets – one injection at 7 weeks of age

Piglets Sow + Piglets Regular Sow + Piglets

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

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

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…

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.

THANK YOU !
