Overall objective

  • Quantify the impact of IBV variants on egg production and propose mitigation strategies for the variants the impact layer flocks in Canada.

Specific objectives

  • Isolate major variant infectious bronchitis virus (IBV) strains originating from broiler and layer flocks in Canada.
  • Determine whether the isolated Canadian variant IBV strains cause abnormalities in the reproductive tracts of young and adult chickens leading to lower egg production and fertility problems.
  • Estimate the economic impact of IBV on the Canadian poultry industry.
  • Formulate disease mitigation strategies suggesting potential vaccine candidate strains with a view of minimizing the impact of variant IBV on egg production and fertility.
