What is the cause of the swollen head and swollen face of laying hens

Lack of sleep, drinking too much water before going to bed, and some medications taken before going to bed may also be caused, and the main cause of body edema is that too much water is accumulated in the body and cannot be discharged. A common cause of puffy eyes in the morning is drinking too much water before bed or eating too much salt. In addition, during menstruation, if the menstrual qi is not smooth, the swollen eyes will come together with dark circles; Of course, lack of sleep and impaired blood circulation can also cause water to accumulate in the eyes.

Dietary swelling reduction method.

Normally, water absorbed from food and drink is excreted from the body through the blood and lymphatic circulation through the sweat glands and urethra.

Excessive salt intake can lead to water retention in the body and puffiness. Therefore, in order to maintain water balance, it is necessary to excrete excess water from the body, and eating more foods that enhance water circulation can help reduce swelling.

In addition, it is necessary to reduce the intake of foods that make the body susceptible to cold, cold drinks or foods that increase the burden on the stomach, so it is easy to tire the stomach and intestines and retain water in the body. In addition, to cope with edema, mild or diuretic foods should be taken in a balanced manner, and to rest the stomach, the diet should also be reduced at night, and a large amount of water should not be consumed.

Absorbing more calcium on a daily basis can also help flush out excess water produced by salt in the body. Foods rich in calcium include apples, corn, lentils and hard tofu. In addition, you may want to eat more of the following foods that promote water circulation and diuretic effect.

Many chicken farmers will encounter the phenomenon of swollen heads and faces in the process of raising chickens. The symptoms of sick chickens are fever and lack of energy, which slows down the growth rate and egg production rate of the chickens. So what is the cause of head and face swelling in laying hens? Let's find out.

1. Swollen head syndrome.

Swollen head syndrome is the main symptom of lumps such as chicken heads, chicken faces, corns, etc., and it is also characterized by rapid transmission, usually appearing within two days. The disease is caused by infection of birds with avian pneumovirus. The first symptoms are mainly sneezing and coughing.

Subsequent lesions usually begin in the eye. Common manifestations include swollen lacrimal glands and redness of the conjunctiva, and in some cases, edema may even spread to the whiskers, jaw, and upper neck. In addition to the symptoms corresponding to the name "swollen head", sick chickens infected with swollen head syndrome often show symptoms such as green and foul-smelling feces, bad mood, inability to eat, circular, and significantly reduced egg production.

2. Mycoplasmosis.

It is caused by infection with mycoplasma sepsis, and is mainly characterized by inflammation of the nasal cavity and sinuses of chickens, swelling of the infraorbital sinuses, swelling of the eyelids, swelling of the eye glands, and tears flowing from the corners of the eyes. If the disease lasts a little longer, there will be a whitish-yellow cheese-like substance in the eyes. Sick chickens have difficulty breathing, pounding, and rales in their breathing.

3. Escherichia coliosis.

The face of the chicken head is swollen, and he can't even open his eyes, and he has difficulty breathing, and his breathing has rales. There is a large amount of yellowish jelly-like exudate and cheese-like exudate under the head and face**.

4. Avian cholera.

Caused by Pasteurella, most sick chickens are chronically infected, with swollen heads and hard textures. Acute cases often die without seeing the lesions.

5. Avian influenza.

Influenza caused by avian influenza viruses, which manifests as swelling of the face and swelling of the flesh, is highly contagious. One is that the flock has severe respiratory symptoms, difficulty breathing, and the chickens will open their mouths to breathe and make strange noises. If the chicken has the first symptoms of the flu, in addition to the swollen head and face, there will also be a significant runny nose.

In conclusion, there are many causes of facial swelling of the head of laying hens. Chicken farmers need to judge what kind of disease is based on the symptoms of sick chickens, and then do a good job of prevention and control.

It may be swollen head syndrome, this disease will be manifested in the chicken's head is very large, there is no way to eat something, the mental strength is relatively poor, and the egg production will decline.

It may be an E. coli infection, which is a very common disease that has a very large impact on chickens and should be treated in a timely manner.

The main symptoms of this condition are sneezing, flushing of the conjunctiva of the eyes, and the appearance of a swollen head and face.

Causes of the disease:

Swollen head syndrome: head and face edema, dyspnea, cough and runny nose caused by avian pneumovirus (SHS). The disease is contagious and can be transmitted from one house to another, and the mortality rate of meat babies increases after the onset of the disease, and the egg laying rate decreases by about 15% when egg production occurs.

The manifestation caused by the virus is that the face of chickens is swollen, the flesh of chickens is swollen, and the disease is highly contagious. First of all, severe respiratory symptoms occurred in the flock, dyspnea, mouth open to breathe, strange screams, and acute death, and bleeding from the scales of the shin and plantar part of the leg was its characteristic manifestation.

Infectious laryngotracheitis: caused by a throat virus, manifested by unilateral eyelid swelling, infraorbital sinus swelling, clear tears in the corners of the eyes, tear-like drops.

Escherichia coli: the disease manifests itself as swollen head and swollen face, and even chicken's eyes cannot be opened, difficulty breathing, and respiratory rales. There was a large amount of yellowish jelly-like exudate and cheese-like exudate under the skin of the chicken head face.

Avian cholera: caused by pasteurella, the disease is mostly chronic, showing that the meat of chickens is swollen and hard. In acute cases, death is often achieved without the lesion being seen.

Snotty, sneezing, swelling of the chicken's face, conjunctivitis, decreased egg production, growth arrest. Chickens have a large amount of cheese-like exudate within the infraorbital sinus.

Mycoplasmosis: caused by Mycoplasma septicaeum infection, the main characteristics are the nasal cavity of chickens, inflammation of the sinuses of chickens, swelling of the infraorbital sinuses of chickens, swelling of the eyelids of corns, bulging glands of corns, and foamy tears flowing out of the corners of corns. Dyspnea, nasal flicking, rales in breathing, and death from secondary E. coli.

1. Swollen head syndrome: head and face edema, dyspnea, cough and runny nose caused by avian pneumovirus. The disease is contagious and can be transmitted from one house to another, and the mortality rate of broiler chickens increases after the onset of the disease, and the egg laying rate of laying hens decreases by about 15.

2. Avian influenza: Avian influenza caused by avian influenza virus manifests swelling of the face, swelling of the flesh, and the disease is highly contagious. First of all, the flock of flocks has severe respiratory symptoms, dyspnea, chickens open their mouths to breathe, make strange noises, and have acute death, and the shin and plantar scale bleeding of chicken legs is its characteristic manifestation.

3. Infectious laryngotracheitis: caused by laryngeal virus, manifested unilateral eyelid swelling, infraorbital sinus swelling, clear tears in the corners of the eyes, tearful drops.

4. Escherichia coliform disease: Sick chickens show swollen heads and swollen faces, and even their eyes cannot be opened, and they have difficulty breathing and have breath sounds. There is a large amount of yellowish jelly-like exudate and cheese-like exudate under the skin of the head and face.

5. Avian cholera: caused by pasteurella, the sick chickens are mostly chronic, showing swollen flesh and hard texture. In acute cases, death is often achieved without the lesion being seen.

6. Avian infectious rhinitis: caused by Haemophilus parachiobacterium. The main features are inflammation of the nasal cavity or sinus, runny nose, sneezing, swelling of the face, conjunctivitis, decreased egg production, growth arrest. There is a large amount of caseous exudate in the infraorbital sinus.

7. Mycoplasmosis: caused by Mycoplasma septicum infection, the main characteristics are inflammation of the nasal cavity and sinuses, swelling of the infraorbital sinuses, swelling of the eyelids, bulging eye glands, and foamy tears flowing out of the corners of the eyes. Sick chickens have difficulty breathing, shake their noses, and breath sounds, and are prone to secondary E. coli to cause death.

Blood in the mucus may be a common cause of nosebleeds.

Surgery is mainly used for rhinitis that has no obvious effect after the drug cannot be **, and can solve nasal congestion.

Corns, swollen head, swollen face syndrome is an infectious disease of chickens caused by avian pneumonia virus and secondary to pathogenic E. coli and other infections, with swollen eyes, swollen head and characteristic neurological symptoms as the main characteristics. Laying hens can also produce fewer eggs and lower hatchability. In the clinical manifestations of chicken disease, swollen face syndrome is more common, which brings certain difficulties to the clinical diagnosis of chicken disease, and it is easy to cause misdiagnosis, so that the farm can not target the drug.
