More broilers per farm / Higher density/m2

With more broilers per farm, improvement of the biosecurity

procedures is essential.

More broilers per farm / Higher density/m2

These conditions make vaccination in the farms more

difficult to be performed in a proper way.

The worldwide trend is to concentrate vaccination in

the hatcheries.

Hatchery Vaccination – In-ovo & SQ (2012)

Country practicing hatchery Injection (> 10 % of production)

Country NOT practicing hatchery injection (< 10 % of production)

Risk of outbreaks with massive losses

Use of more effective vaccines that are able to reduce

the shedding of challenge pathogens.

Vaccination performed in the hatcheries and in a more

automated way through in-ovo or subcutaneous routes.

Reduction of antibiotics

vaccination reactions (PVR) have been

increasingly replaced by safer vaccines

Conclusions

The industry has completely changed over the past decades

and it has brought new challenges to producers:

Huge production complexes located in very densely populated areas;

High stocking densities in the farms;

High disease pressure;

Poorly qualified workers,

Pressure to reduce use of antibiotics

Pressure for animal welfare

Etc

Within this new context, vaccination procedures have clearly

evolved.

Conclusions

What should we expect from a vaccine?

Safety (in ovo or day-old application to susceptible birds)

Clinical Protection

Increased resistance to infection

Reduction of shedding

Induction of immunity in face of MDA

Long duration of immunity

Monitorability (DIVA)

Easy to administer (mass application in the hatcheries)

Biosecurity remains a critical part of this puzzle.
