Confidentiality is assured, and only collective data will be usedin any reporting.2. Epidemiological Survey in Southeast QueenslandA precise epidemiological study on the causes of mortality in a selected number of SoutheastQueensland commercial free-range flocks will be conducted.Approximately five free-range flocks will be selected for this focused epidemiological studyfor approximately three to six months. Farms that agree to be involved in this part of theinvestigation will be required to complete a detailed questionnaire, allow collection of bloodand faecal samples at the start and end of trial, keep accurate records and store allmortalities from the flock being studied. Farms will be provided with all equipment/suppliesneeded to undertake this work.All mortalities will need to be stored on-farm in a freezer for regular collection by project teammembers for pathological assessment. The project can assist with freezer units forparticipating farms if required.
