Infectious Bronchitis (IB) is a highly contagious disease affecting poultry globally. It can damage respiratory, urinary and reproductive systems depending on the viral strain.

Vaccination is the main tool to control IB and preserve flock health and performance. A well-designed vaccination programme adapted to the local IB virus strains reduces disease outbreaks, improves uniformity and protects egg production in layers.

Vaccines must match circulating virus variants to maximize protection. Good vaccination strategy also includes monitoring and management to ensure the flock remains protected.

Key points

• IB affects multiple systems (respiratory, renal, reproductive) depending on strain tropism.
• Vaccination programmes tailored to local IB virus variants are essential for effective control.
• Proper vaccination helps maintain flock performance and protect production parameters.
