How to prevent sudden death in laying hen cage chickens

Sudden death in laying hens has been more common in recent years. Sudden death in laying hens, also called laying hen cage fatigue, is the most prominent conditional metabolic disorder in laying hens. How to prevent and cure this disease.

I. Clinical manifestations:

Sudden death of laying hens is divided into acute and chronic. Generally, the acute laying hens will die suddenly after the disease appears, and the egg production rate of newly-launched flocks will be between 20% and 60%. The higher the egg production rate, the higher the mortality of chickens. Farmers can observe that the cloaca of dead chickens will be prominent and accompanied by hyperemia.

Control measures:

1. Before the laying hens start production, that is, the chicken breeding stage, the farmers should pay attention to ensuring the quantity and quality of bone meal in the feed to supply sufficient calcium and phosphorus.

2. In the process of raising chickens in laying hen cages, farmers must keep them in accordance with the standard feeding density. They cannot increase the feeding density at will, especially in summer, they should appropriately reduce the feeding density, strengthen ventilation, and reduce Heat stress prevents high temperature and hypoxia. For large-scale intensive chicken farms, farmers need to use fan equipment for vertical ventilation. The ventilation effect is better, which can create a comfortable environment for the chicken house.

3. In the daily prevention work, farmers should use antibiotics to prevent fallopian tubes and enteritis. Drinking 30,000 units of water per penicillin has a certain effect.

4. Farmers can add vitamin C to the feed for laying hens, which can alleviate the disease for the laying hens.

5. If the layers of the breeder's laying hens have more severe layers, it is recommended that the farmers reduce the blood viscosity and reduce the burden on the severely affected flocks. You can turn on the lights 1-2 times late at night to let the chickens drink water and pick Place the paralyzed chicken in the shade.
