Control cannot be accomplished with drugs alone. Management is equally important. A bacterin is available that can be used in a control or eradication program. The bacterin requires multiple injections to be effective which makes it costly and cumbersome for commercial flocks. Control requires attention to flock sanitation, biosecurity, preventive medication, clean and sanitary premises, and disease-free replacements.
Most outbreaks occur as a result of mixing flocks.
If you have an outbreak, segregate birds by age, etc., properly dispose of dead birds, medicate to stop the spread of the disease and initiate eradication procedures. Do not save recovered birds for breeder replacements. Premises should be vacant for 30 to 60 days after cleaning and disinfecting before repopulating or onset of the new season. Breeders should be replaced from a Coryza-clean source. This article originally appeared in the December 1997 Issue of The UPA Newsletter .
