10. French Infectious bronchitis epidemiology
% of broiler production per department
830 million broilers
43 million layers
45 millions turkeys
120 million ducks
….Multi species production
Infectious bronchitis viruses are
circulating.
Need for a good viral protection

11. French Infectious bronchitis epidemiology
Vaccination with Mass vaccine is done on 100 % of the birds, at the hatcheries.
Field boosting with either 793 B or QX are applied according to veterinarian, integration or farmer decision related to IB perceived pressure or type of broilers produced (big birds). D0
D10-D14
D16-D20

GUMBORO
We used to have this vaccination program before ibird.

12. French Infectious bronchitis epidemiology
=> Vaccination at the hatchery is not perceived as critical by the independant hatcheries => Field vaccination is usually applied by spray with no regular monitoring. Need for LDC -to get better control of vaccine & protection on the production. -to get better evaluation of epidemiological situation in real time
2 concerns with that program 12

Some respiratory signs after 10 days in 9 out of 230 flocks :
1 IB titers OK
1 positive for ORT
1 positive for MS
2 IB PCR >0 no identification possible
4 IB PCR >0 for IBird, no conclusion other cause ? 21

22. Conclusion
Hatchery vaccination with Mass & Cevac IBird gave consistent seroconversion at slaughter It can be used as hatchery vaccination monitoring Hatchery spray application was improved with equipement setting & control Field virus circulation was detected between 28 % and 38% of the farms according to the period. Reinforced the need of a complete and well applied vaccination program in our production area. 22
