10 French Infectious bronchitis epidemiology 830 million broilers 43 million layers 45 millions turkeys 120 million ducks.multi species production Infectious bronchitis viruses are circulating. % of broiler production per department 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 IB Mass Strain (Hatchery) IB Variant Strain (Field vaccination) 793B/QX GUMBORO

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 12

13 Actions : a new vaccination program Big birds Certified birds D0 D16-D20 IB Mass Strain + IB Variant strain (Cevac IBird). Hatchery GUMBORO HATCHERY IB Vaccination. Monitoring Implementation

14 Actions 230 different poultry houses In 2 regions from nov 14. Vaccination Mass & Cevac IBird spray day 1 7 different hatcheries Control of spray equipment & CHICK Program implementation 3 different organisations Monitoring of day 10 PVR & respiratory signs during growing period 3 different slaughterhouses

15 Monitoring implementation 230 different poultry houses In 2 regions from nov 14. Vaccination Mass & Cevac IBird spray day 1 7 different hatcheries Control of spray equipment & CHICK Program implementation 5 different organisations 3 different slaughterhouses Monitoring of day 10 PVR & respiratory signs during growing period Sampling & Analysis for epidemiological monitoring 10 Blood samples per flock : Biocheck Elisa Cecal tonsils: frozen and PCR analysis according to Elisa & farm results 15

16 Desvac In-Line sprayer Hatchery spray evaluation Desvac In-Line sprayer

17 Results : Safety 1 out of 230 flocks with mortality before 10 days, after veterinarian visit it was due to E coli infection 17

18 Results : IB ELISA MEAN TITERS

19 Results : IBV mapping October-December 2014, 28% of the farms are challenged by a field virus (T> 3000) No vaccination< < «normal»< 3000 Doubtfull > 3000, high CV Field infection > 3000, low CV

20 No vaccination< < «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)

21 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? 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
