Symptoms

The risk to your operation

IB threatens every poultry operation, and it can seriously limit your productivity through increased mortality, reduced egg production and condemnation losses. Infectious Bronchitis (IB) also leaves your flock vulnerable to other disease threats, like airsacculitis, a major cause of condemnations.

IB symptoms: IB is a highly contagious viral disease affecting the respiratory tract, occurring in chickens. Infected birds may show symptoms such as:

  • Coughing and snicking
  • Nasal discharge
  • Depression
  • Reduced quantity and quality of eggs
  • Silent layers (These are layers with underdeveloped oviducts due to IB infection at less than two weeks of age. Birds appear normal, but do not lay eggs.)
  • Acute Mortality due to gout related to kidney infection and failure
  • Condemnations due to secondary Escherichia coli infections​

Treatment and prevention: There is no specific course of treatment for infected birds. For IB prevention, a sound vaccination program is recommended.

Effective IB prevention starts with the right parts.

The Poulvac® IB vaccine portfolio is designed to give you more protection options for the long-term health of your flock and your business. We'll work with you to ensure proper strain diagnosis, vaccine administration, monitoring and follow-up.
