Egg drop syndrome

Egg Drop Syndrome (EDS) is a viral infection that affects laying hens, causing a decrease in egg production and quality. The disease is caused by the Egg Drop Syndrome Virus, a member of the Adenovirus family.

Symptoms

The primary symptom of EDS is a sudden decrease in egg production, often by as much as 40%. Affected hens may also lay eggs with thin or soft shells, or with no shell at all. The eggs may also be misshapen or discolored. In severe cases, the hens may stop laying eggs altogether.

Transmission

EDS is primarily transmitted through the fecal-oral route. The virus can also be spread through contaminated feed, water, equipment, and clothing. It can also be passed from infected hens to their offspring through the egg.

Diagnosis

Diagnosis of EDS is based on the clinical signs and confirmed by laboratory testing. The most common tests used are the ELISA test and the Virus Neutralization Test.

Treatment and Control

There is no specific treatment for EDS. Management strategies focus on preventing the spread of the virus through good biosecurity practices. Vaccination is also used in areas where the disease is endemic.
