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

D0 D10-D14 D16-D20
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).
=> 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

Results :

1 out of 230 flocks with
mortality before 10 days,
after veterinarian visit it was
due to E coli infection

Results : IB ELISA MEAN TITERS
Results : IBV mapping
October-December 2014, 28% of the farms are challenged by a field virus (T> 3000)
No vaccination< 500 1000< « normal »< 3000 Doubtfull > 3000, high CV
Field infection > 3000, low CV
Results : IBV mapping
December 14 – February 15 , 38% of the farms are
challenged by a field virus (T> 3000)
No vaccination< 500 1000< « normal »< 3000 Doubtfull > 3000, high CV
Field infection > 3000, low CV
Results :
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 ?

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.
