Kemin and Poultry World invite you to the 2025 Respiratory Integrity Forum, where global experts will discuss integrated risk management against emerging respiratory challenges compromising welfare and profitability in your poultry operation.

On May 8 at 13:00 CEST, our experts will share key insights into infectious bronchitis.

Register now to join live for free or watch the webinar later on demand!

Key Takeaways:

  • Infectious Bronchitis Virus – Risk factors & epidemiological updates.
  • Infectious Bronchitis Control – Best practices with vaccination.
  • Infectious Bronchitis – Field results building respiratory integrity with Kemin vaccines.

Infectious Bronchitis virus (IBV) is a major respiratory virus which causes chronic disorders leading to financial losses in the poultry industry worldwide. IBV infection of the oviduct at a very young age can lead to permanent damage and, in hens, can significantly compromise the production period. IBV can also be nephropathogenic, thus causing acute nephritis, urolithiasis and mortality, especially in young birds. The error-prone viral polymerase and recombination mechanisms lead to a diverse viral population with multiple genotypes, serotypes, pathotypes and protectotypes. This antigenic complexity significantly complicates control and mitigation strategies based on vigilance in biosecurity and the deployment of suitable vaccination. Besides the IBV classical strain (Massachusetts), there are dozens of variant strains, such as the GI-23 lineage strains (countries in red), which have been spreading to multiple geographies worldwide (Fig. 1)

When it comes to vaccination, if the main challenge pressure comes from “variant” strains, the primer vaccine should contain a variant antigen (e.g. VAR 2) and the booster immunization should contain the classical strain (Fig. 2). The success of your vaccination program is incredibly valuable to Kemin. Join this global forum to learn more about the product profile and field results obtained with our respiratory vaccines.
