  • 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.

Transcript

  • 1. Bulgarian pig production and CIRCOVAC sow and piglets field experience Dr. Milena GROZEVA, DVM SAM BS Ltd. 15 / April / 2011 Malta
  • 2. Bulgaria
  • 3. Distribution of swine farms ROMANIA SERBIA MACEDONIA TURKEY GREECE BLACK SEA
  • 4.
    • Area - 110,993,6 km 2
    • Population – 7 628 103
    • EU – 2007
    • Climate - moderate and transitional-continental
    • huge temperature variation in swine producing regions + 40 ˚ C / - 30 ˚ C
    • 36 890 accessible sows in 37 farms
    • Traditional pork consuming people
    BULGARIA
  • 5. Yearly trend in number of accessible / industrial pigs and farms The total number of farms decrease mainly due to closing of small farms
  • 6. Distribution of industrial (accessible) pigs in different types of farms 23 farms manage ≈ 90% of industrial sows
  • 7. Distribution of swine genetics in Bulgaria
  • 8.
    • Number of sows – 2700
    • Genetic - farm № 41
    • One place, breeder fattener farm
    • Number of batches – 8
    • Batch management - 4 days
    • Type of flow – all in, all out
    • Health status: no PRRS
    Swine farm “Brashlen”
  • 9. Vaccination protocol - sows : 1w 2w 3w 4w Parvovirosis +Erysipelas E. coli 1w 2w Farowing
  • 10. Vaccination protocol - gilts : 5w 3w 4w Parvovirosis +Erysipelas 1w 2w Insemination 3 ws E. coli 6w 7w Farrowing E. coli 1w Parvovirosis +Erysipelas 4w
  • 11. Vaccination protocol - piglets : 2 nd week of age 4 nd week of age Mycoplasma hyopneumoniae Up to December 2010 – RespiSure (2x) From January 2011 - Porcillis Mhyo
  • 12. Vaccination protocol - boars : Parvovirosis +Erysipelas 6 months Parvovirosis +Erysipelas
  • 13. Vaccination against PCV2 - WHY?
    • Increased % ” lightweight ” pigs , especially
    • in fattening period
    • Mortality rate - slight increase in fatteners (2%)
    • Single cases of PDNS
  • 14. Vaccination against PCV2 - WHY?
    • Necropsy – stomach ulcers
    • Performance lower than TOP DanBred farms
    • Laboratory – serology
  • 15. First choice - CIRCOVAC on piglets - WHY?
    • Farm performance before vaccination
    • No visible reproductive disorders
    • Farrowing Rate >90%
    • ADWG in growers – 0,566 kg
    • ADWG in fatteners – 0,983 kg
  • 16. CIRCOVAC - Piglet MASS vaccination - PROTOCOL
    • All pigs at age 29-100 days
    • Dose - 0,5 ml, IM
    • Start – February 2009
  • 17. CIRCOVAC - Piglet REGULAR vaccination - PROTOCOL
    • Dose - 0,5 ml, IM
    • Time of vaccination - at weaning (29 days)
    After mass sow vaccination – piglets vaccination was postponed to 7 weeks of age
  • 18. After good piglets results – sow vaccination - WHY?
    • A lot of published data about influence of PCV2 on reproduction.
  • 19. After good piglets results – sow vaccination - WHY?
    • Very good actual farrowing rate, but opportunity to reach TOP results in number of born/weaned piglets
  • 20. 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
  • 21. CIRCOVAC - Sow REGULAR vaccination - PROTOCOL
    • 1 dose = 2 ml, IM
    • One injection at each gestation at least 2 weeks before farrowing
  • 22. 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 each farrowing
  • 23. CIRCOVAC - Piglets & sow vaccination – WHY? First results in ADWG & Total born piglets per litter Piglets Sow & Piglets ADWG growers 558 614 Total piglets per litter 13,2 15,6
  • 24. CIRCOVAC - Piglets & sow vaccination – WHY? Live born piglets /sow/year ADWG Sow vaccination Piglet vaccination Total herd performance Sow & Piglet vaccination x Different targets Different approaches
  • 25. CIRCOVAC - Sow & piglets – REGULAR vaccination – PROTOCOL
    • Start – December 2009
    • Sow – One injection at least 2 weeks before each farrowing
    • Gilts – Primary vaccination- 2 injections in 3 weeks intervals, Booster – 1 inj. 2 weeks before farrowing
    • Piglets – one injection at 7 weeks of age
    • Boars – every 6 months

  • 27. Data collection and analysis
    • Check list
    • Farm software – Agro Soft
    • No control group (control – farm parameter before CIRCOVAC)
  • 28.
    • No revolution in the farm from 2008
    • Improvement of management programs
    • Use of self replacement gilts – no import of gilts, only boars
    • Changes in ventilation system
    • The farm is “live” and dynamic
    Swine farm “Brashlen”
  • 29.
    • First (visible)
    • observations :
    • Disappeared stomach ulcers
    • Very well uniform piglets
    Benefits of CIRCOVAC - piglet vaccination
  • 30. Significant improvement of ADWG P<0.05 (Dunett test) + 41 g ADWG in growers + 77 g ADWG in fatteners
  • 31. Benefits of CIRCOVAC sow vaccination on reproductive parameters + 3,7 born piglets / litter P<0.05 (Dunett test) Control Sows vaccinated
  • 32. Benefits of CIRCOVAC sow vaccination on reproductive parameters P<0.05 (Dunett test) Control Sows vaccinated + 3,1 live born piglets / litter
  • 33. Benefits of CIRCOVAC sow vaccination on reproductive parameters P<0.05 (Dunett test) Control Sows vaccinated + 0,8 weaned piglets / litter
  • 34. Days from birth to 100 kg
  • 35. CONCLUSION
    • In farm “Brashlen” CIRCOVAC :
    • increases the reproductive performances – number of live born piglets
    • improves the pig growth from birth to slaughter
    • r educes the duration to slaughter
    • helps for homogenous pig batches
    • provides sustained protection of piglets as from the suckling phase
    • restore mortality rate
    • preventing PCVD clinical signs
