Cuba has implemented immunization programs against IBV and NDV, administering live or inactivated vaccines to the breeding or laying hen stocks, respectively A number of diverse methodologies are currently employed for the diagnosis of the main viral and bacterial agents associated to CRS, ranging from the conceptually simple methods corza as the isolation of the microorganism itself, to the technically complex methods such as molecular assays.
In addition, a fourth dose of the NDV vaccine was applied, due to the low proportion of responding individuals according to the HIA titers after the third dose. After reaching 16 weeks, they were transferred to a Commercial Layers Unit, under a productive system of mixed ages, with a history of outbreaks of respiratory processes.
