Abstract: This thesis is an investigation of the changes in production performance in nursery and grower-finisher pigs associated with an outbreak of porcine reproductive and respiratory syndrome (PRRS) and an examination of the economic impact of this disease. The production records from herds experiencing a PRRS outbreak were used. The 6-month period prior to the outbreak was compared to the 6-month period after the outbreak and to the period 7-12 months after the outbreak. Cost was attributed based on the average reduction in performance parameters including growth rate, feed efficiency and mortality. The overall cost per annum to nursery and grower-finisher pigs due to PRRS in the Ontario was estimated to be approximately $4 million. This value was calculated by developing an economic model taking into account the size of the Ontario swine population and the average incidence of PRRS outbreaks.
