dc.description.abstract	Infectious bronchitis is a common, highly contagious, acute, and economically important viral disease of chickens caused by infectious bronchitis virus (IBV), a gammacoronavirus. It affects the respiratory system, reproductive organs, and kidneys. Morbidity is 100%, and mortality can go well up to 30%, while egg production drops by up to 50% or more depending upon secondary infection by bacterial pathogens. Emerging IBV variants have led to outbreaks in vaccinated flocks due to a lack of cross-protective immunity, which represents a concern for producers. It is imperative that we assess the economic impact of IBV on the Canadian poultry industry to make important decisions on control and mitigation. I hypothesized that vaccination to prevent infectious bronchitis (IB) in poultry layers would have net positive economic benefits for Canadian poultry producers. A multiple scenario framework with Monte Carlo simulation and benefit-cost analysis was applied. The economic impact of IB on layer farms in Canada was examined by setting up models of Canadian layer poultry farms using data from Agriculture and Agri-Food Canada, scientific papers, the internet, and industry sources to perform simulations for various revenue classes across a range of IBV infection scenarios while considering possible control and prevention options. The results show that the impact of IB outbreaks on Canadian poultry industry is estimated to be around 207 billion CAD annually. The high benefit-cost ratios (5-9) from adopting IB vaccines suggest that vaccination as a preventive strategy would be highly cost effective. The study demonstrated the value of vaccination as a preventive or mitigation strategy against potential losses due to IBV. Understanding the extent of economic losses IB outbreaks cause to layer producers would inform the development of timely and cost-effective disease control and preventive measures in order to minimize the impact of IB on egg and chicken production.	en_US
