Infectious bronchitis virus (IBV) is one of the most economically damaging diseases in modern poultry production. Affecting both broilers and layers, IBV’s rapid evolution and ability to interact with other respiratory pathogens make it highly contagious and challenging to control.
Ceva’s integrated IB solution addresses these challenges with a scientifically validated approach centered around broad-spectrum vaccines, optimized hatchery vaccination technology, and robust monitoring programs.
Understanding IBV Epidemiology and Evolution
IBV exhibits significant genetic variability, particularly in the S1 gene, which leads to rapid mutations and the emergence of new variants. Field surveillance emphasizes the interrelatedness of IBV circulation, with frequent co-infections identified alongside agents like Mycoplasma, E. coli, ILTV, NDV, and strains of avian influenza.
The Integrated IB Control Concept
The concept of integrated control is built on three foundational pillars:
1. Vaccination Quality and Simplification
Ensuring uniform protection from day one through advanced hatchery vaccination systems, such as Desvac sprayers using flat nozzle technology, enhances spray coverage, droplet size consistency, and vaccine take.
2. Disease Control
The integration of broad-spectrum cross-protection against multiple genotypes, underpinned by robust data management and epidemiological oversight.
3. Disease Prevention
Implementing strategies to reduce virus shedding and minimize environmental pressure through effective early-life immunity is crucial.
This integrated system aligns with contemporary poultry production models that require scalable, replicable IB control methodologies.
Hatchery Vaccination: The Starting Point
Effective day-old vaccination is vital for successful IB management. Focus areas include:
- Crate coverage
- Droplet homogeneity
- Correct droplet size
Addressing these criteria is essential for maximum vaccine uptake, as illustrated by field monitoring data.
Conclusion: Embracing Integration as the New Standard
With intensifying global poultry production systems, IBV continues to adapt and evolve. Disjointed approaches to disease management are increasingly ineffective.
Comprehensive, scientifically validated strategies are essential for controlling IBV. An integrated solution that combines vaccine strategies, advanced hatchery technology, and data-driven monitoring delivers:
- Early and enduring immunity
- Extensive genotype cross-protection
- Substantial reductions in virus shedding and environmental pressure
- Minimized transmission of the virus
For producers and integrators, the takeaway is clear: effective IB control commences early, is predicated on precision, and thrives through integration.
