    • 4TH MERIAL FORUM HAVE WE GOT PCVD &SWINE INFLUENZA UNDER CONTROL?
    • PCVD Moderator: Dr Stéphane Imbert• Viral reproductive disorders in sows, an update 2012. Pr. H. Nauwynck• Benefits of CIRCOVAC® piglet vaccination in Hngary. Dr T. Kecskés• Additional benefits of sow and piglet CIRCOVAC vaccination: Bulgarian field experience. Dr M. Grozeva
    • 4TH MERIAL FORUM HAVE WE GOT PCVD &SWINE INFLUENZA UNDER CONTROL?
    • ADDITIONAL BENEFITSOF SOW AND PIGLET CIRCOVAC VACCINATION Bulgarian field experience
    • CIRCOVAC : a dual approach for the total herd performance benefits Different Different targets approaches Piglet performance Reproductive Total herd performance performance xPiglet vaccination Sow vaccination Sow & Piglet vaccination
    • BULGARIA
    • ROMANIASERBIA 110,993,6 km2MACEDONIA Bulgaria TURKEY GREECE
    • BULGARIA 7 628 103 2007 Moderate and transitional-continental Huge temperature variation in swine producing regions + 40˚ C - 30˚ C
    • BULGARIA  36 890 accessible sows in 37 farms  Traditional pork consuming people
    • Distribution of industrial (accessible) pigs in different types of farms 1% 10% Large Farrow-to-Finish Farms (>400 pigs) Small Farrow-to Finish Farms (<400 pigs) 89% Fatteners Farms 23 farms ≈ 90% of industrial sows
    • Distribution of genetics
    • One site, farrow-to-finish farm(>30 000 pigs at any moment)
    • Swine farm “Brashlen” Number of sows – 2700 250 hectares Genetic - farm № 41 Number of batches – 8 Batch management – 4 days Type of flow – all in, all out
    • Health status of the farm PRRS (-) App (+) M. hyo (+) Aujezsky (-)
    • Vaccination against PCV2 - Why?
    • 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 beforevaccination 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 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 MASSvaccination - PROTOCOL All pigs at age 29-100 days Single injection - 0,5 ml, IM
    • CIRCOVAC - Piglet REGULARvaccination - PROTOCOL All pigs at weaning (28-29 days) Single injection - 0,5 ml, IM
    • Benefits of CIRCOVAC - pigletvaccination First (visible) observations :Disappeared stomach ulcers  Very well uniform piglets
    • Significant improvement of ADWG Growing Fattening610 1080 1060 1052*600 590 1040590 1020580 1000 983570 566 980 960560 940550 920540 900 Before Piglets Before Piglets + 24 g ADWG in growers + 69 g ADWG in fatteners
    • Days from birth to 100 kg - 4 days
    • After good piglet results – sowvaccination – WHY?A lot of confirmations of influence of PCV2 on reproduction
    • After good piglet results – sowvaccination – WHY? • Very good farrowing rate… …but opportunity to reach better results in number of born/weaned piglets
    • 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 REGULARvaccination - PROTOCOL One injection at each gestation at least 2 weeks before farrowing Dose – 2 ml, IM
    • CIRCOVAC – Gilts REGULARvaccination - 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
    • Benefits of CIRCOVAC - sowvaccination Total born/litter 18 16* 16,7* 15,5* 16 14 13 13,3 12 10 controls piglets 2010S1 2010S2 2011T1 + 3,7 born piglets / litter Control P<0.05 (Dunett test) Sows vaccinated
    • Benefits of CIRCOVAC - sowvaccination Live born/litter 16 14,9* 13,9* 14,2* 14 11,8 12 12 10 controls piglets 2010S1 2010S2 2011T1 + 3,1 live born piglets / litter Control P<0.05 (Dunett test) Sows vaccinated
    • Benefits of CIRCOVAC - sowvaccination Weaned /litter 12,5 12,2* 12 11,2 11,4* 11,5* 11,5 11,1 11 10,5 10 controls piglets 2010S1 2010S2 2011 + 1 weaned piglet / litter Control P<0.05 (Dunett test) Sows vaccinated
    • CIRCOVAC - Sow & piglets – REGULAR vaccination PROTOCOL Sow – one injection at least 2 weeks before each farrowing Gilts – Primary vaccination – 2 injection, 3 weeks apart, booster – 1 injection, 2 weeks before farowing Piglets – one injection at 7 weeks of age
    • IMPORTANT !!! After mass sow vaccination – piglets vaccination was postponed to 7 weeks of ageFarrowing Weaning Begin. of Finishing Slaughter Weeks of age 28 days 7 weeks
    • CIRCOVAC – Boar – REGULAR vaccination 6 months apartTransmission of porcine circovirus 2 (PCV2) by semen and viral distribution in different piglet tissues1Danielle Gava2, Eraldo L. Zanella3,Nelson Morés4 and Janice R.Ciacci-Zanella5*
    • CIRCOVAC - Sow + PigletsThe best improvement of ADWG Growing Fattening 607* 610 602* 1080 1060* 1060* 600 1060 1052* 590 590 1040 580 1020 570 566 1000 560 983 980 550 540 960 940 1 09 s re et 01 fo 20 gl /2 Be Pi ts 10 920 le 20 g pi s et s+ igl 900 w so p s+ Before Piglets sows+ piglets sows+piglets w 2009 2010/2011 so + 41 g ADWG in growers + 77 g ADWG in fatteners
    • Days from birth to 100 kg 150,7 - 5,3 days 145,3
    • Summary of vaccination protocol 2009 Feb Mar Apr May June July Aug Sept Oct Nov Dec 2010 Jan Feb Mar Apr May June July Aug Sept Oct Nov Dec 2011 Jan Feb Mar Apr May June July Aug Sept Oct Nov Dec 2012 Jan Feb Mar Apr May Piglets Sow + Piglets Regular Sow + Piglets
    • 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
    • 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
    • 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.
