Prevention and treatment of sudden death syndrome in laying hens

Sudden death syndrome of laying hens, also known as egg-laying fatigue, generally refers to the sudden death or paralysis of caged laying hens, some of which will produce soft-shell or thin-shell eggs, reducing the laying rate. So what is the cause of the sudden death of laying hens? How to prevent and cure it? let's take a look at the detailed introduction.

1. The cause of disease

In the high temperature in summer and autumn, the climate is hot and humid, but the breeding density of chickens is too high and the equipment is poor, which leads to poor ventilation in the chicken house, high temperature, accelerated respiration of chickens, and the imbalance of acid and alkali in chickens. Respiratory alkalosis, resulting in sudden death. In addition, when feeding in summer, there is no change in the feeding mode, feeding 3-4 times a day, or feeding at high temperature, which virtually increases the burden on the heart of chickens, leading to heart failure and sudden death.

2. The regularity of the disease

The disease mainly occurs in laying hens, in which the raw food of the chickens with the first egg laying and the peak producing area will often occur in the surrounding chicken farms when the weather suddenly becomes hot. Chickens will continue to appear paralysis at the beginning, if found in time, the paralyzed chickens can be picked out to return to normal, while some chickens will die at night, dead chickens can be picked out in the early morning, it will be found that the cloaca of dead chickens is prominent, and the proportion of obese chickens is higher.

3. prevention and control measures

It is necessary to strengthen ventilation and ventilation measures in hot weather to alleviate the heat stress reaction of chickens and avoid hypoxia. Biotin can be added to the feed to reduce the mortality of the disease, generally about 300 mg per kilogram. Vitamin C and potassium chloride can also be included in feed, which can alleviate the disease. At the same time, antibiotics should be used to prevent enteritis and salpingitis, which has a certain therapeutic effect. For seriously ill chickens, it can be opened 1-2 times from night to the wee hours of the morning, so that chickens can drink water, reduce hole viscosity, reduce heart burden, reduce mortality, for paralyzed chickens can be placed in a cool place.

The above is the introduction of the prevention and treatment of sudden death syndrome in laying hens. I hope it can help you. If you want to know more about it, please pay attention to us.
