Vaccination in the poultry sector in the
                 region
• Vaccination is based on the prevailing disease
  situation, prevalence, cost of the disease,
  availability of vaccine and the cost/benefit of
  using vaccine
Vaccination in most countries is
        routinely practised against:
•   ND
•   IBD
•   IB
•   Marek’s Disease
•   Fowl Pox
Vaccination is practised in a few
           countries against:
• Coccidiosis
• Mycoplasma
• E. coli
Vaccine delivery systems used in the
              region includes:
•   In ovo (hatchery) Marek’s, IBD
•   Spray (hatchery and field) (IB, ND, Coccidiosis)
•   Subcutaneous or intramuscular (Marek’s)
•   Wing web (pox) (Field)
•   Drinking water on the farm (IB, ND, IBD)
Other conditions mentioned as having negative
           impact on the industry:
• Spiking mortality syndrome in broilers
• Fatty liver haemorrhagic syndrome
• Leg problems
Other conditions mentioned as having negative
           impact on the industry:
• Heat stress (high temp+ high Relative
  Humidity=deadly combination for broilers)
• Nutritional deficiency
• *Management deficiencies
Conclusion
• Vaccination has been successful in reducing
  the prevalence of several diseases to almost
  zero in may instances
Conclusion
• The other diseases and conditions for which
  there are no vaccines are controlled and kept
  at low levels with good management and
  biosecurity practices
Acknowledge
• Thanks to all the poultry vets in the 6
  countries who supplied the information and
  responded at very short notice.

  Suriname)
