Adenovirus Mild Respiratory Disease in Laying Hens

Happenings / Clinical Signs

Respiratory

  • Mild respiratory disease
  • Respiratory signs spread slowly

Adenovirus can be isolated from commercial flocks, even when exceptionally high levels of production or egg quality

A survey of records of virus isolations, clinical, and necropsy findings over a 20 years period, involving hundreds of adenovirus isolations, indicated no primary role for adenovirus in fowl respiratory disease.

Adenovirus can be isolated from commercial flocks, even when exceptional high levels of production and fertility exist, and adenovirus infections of SPF (Specific Pathogen Free) flocks in lay are often associated with little or no effect on either egg production or shell quality

 

Causing Agents
Viral Disease. Virus Adenovirus. Subgroup I aviadenoviruses.
Affected Systems/Organs
Respiratory
Spread
Infected birds, contaminated objects (clothing, footwear, equipment)
Mainly Affects
It may predispose infected birds to have other complications
Solution
Good biosecurity and hygiene programs. Some vitamins and minerals may assist in alleviating respiratory symptoms.
Suggested Actions
  • Can be confirmed with clinical signs and gross lesions
  • Can be dealt with in house
  • Diagnosis should be confirmed with rapid assays and/or a certified laboratory
