Prevention and treatment of Chicken Egg drop Syndrome

Chicken egg drop syndrome is an infectious disease caused by avian adenovirus. Chickens of any age are susceptible. Infection with avian adenovirus affects the production of the whole laying period, mostly through vertical transmission. Chickens are infected through embryos. Chickens begin to detoxify and spread rapidly when the laying rate reaches more than 50%. Let's take a look at the prevention and treatment of egg drop syndrome.

Clinical symptoms of chicken egg drop syndrome

The diseased chickens had no obvious clinical symptoms, and the group laying rate suddenly decreased, accompanied by brown eggs, thin-shell eggs and sand-preserved eggs, and the laying rate of the whole flock decreased by 3050%. Individual sick chickens can see scattered feathers, diarrhea and lethargy. In short, when healthy chickens drop eggs in groups or fail to reach the predetermined level at the peak of egg production, and it is found that the feed intake of chickens decreases, transient diarrhea occurs, and eggshell changes occur, it should be suspected of this disease.

Autopsy symptoms of chicken egg drop syndrome

It can be seen that the diseased chicken ovarian dysplasia, fallopian tube atrophy, follicular liquefaction, uterine and fallopian tube mucosal edema, pallor, hypertrophy, cheese-like substance or white exudate in the fallopian tube cavity.

Preventive measures for Chicken Egg drop Syndrome

3. In the third stage, carbendazide was added to drinking water and layer Jibao was mixed at the same time to eliminate salpingitis and control secondary or mixed infection of Escherichia coli, and rapidly increase the laying rate.
