Chicken knowledge: why does it cause the phenomenon of paralyzed chickens? How to prevent and cure it?

Some chickens are paralyzed when they are raised, and their food and spirit are normal, which is a headache for farmers, so why on earth can it cause the phenomenon of paralyzed chickens? How to prevent and cure it? Next, I would like to introduce you to the knowledge of chicken farming in this area.

First, why will cause paralytic chicken?

1. Enterotoxic syndrome

Generally more than 10-20 days between, easy to panic, legs paralysis, lying motionless, large, head tremor, not legs can not stand, toxin absorbed by broilers, causing paralysis. Just as people drink too much, they lose appetite, explode hair, become white and thin in serious cases, are not formed, there are undigested feed in the feces, some have sparse stools like pulling "tomatoes", and feces like "fish intestines". Before dying, the chicken ran, screamed, paralyzed and fell to the ground and died. Causes: virus infection, Clostridium welchii, intestinal coccidia, mycotoxin and so on.

2. Atypical Newcastle disease in broilers

Broilers generally get sick after 25 days of age, and they often have mild respiratory symptoms at the beginning, and the course of the disease is slightly older, such as wheezing, nose swinging, strange barking, etc., and the chicken crop is enlarged, and it often drips on the trough when eating with its head down.

There is also a soft neck, paralyzed motionless, not the cause of the leg, is the Newcastle disease virus caused nerve damage. In the middle stage, the chicken is lethargic, unwilling to act and take two steps, as well as paralysis in one leg, emaciation, dark red and yellow-green stool in the breast of broilers, and neurological symptoms such as turning neck and twisting neck in the later stage. The cause of the disease: the immune procedure is not in place, many do not do oil vaccine, do not drink water for 21 days, resulting in low antibodies in the later stage, causing disease, or drinking water immune pipeline is not clean and so on.

3. E. coli (arthritis)

Broilers generally occur in chicks or later complicated with Escherichia coli septicemia, chicks with loose feathers, afraid of cold huddling, emaciation, standing alone; discharge of gray and thin feces, pollution of white feces around the anus; sagging wings, joint paralysis and swelling, difficult to stand up. In many cases, walking on one leg is also the case with salmonella. In the later stage, there were symptoms of pericardium and liver, and joint disorders, with green and thin stool in the middle of white rice soup. The cause of the disease: chicks are generally related to the causes of breeding chickens, hatching pollution and other factors, and the sensitivity of opening drugs is also partly due to the fact that large chickens are generally more complicated with infection.

4. Viral arthritis

The disease often occurs in broilers of 3-4 weeks. The chicks are infected, but not necessarily sick, and the contact of diseased chickens spreads quickly. It is easy to occur in successive batches with excessive humidity, serious morbidity, severe paralysis, dark red joint swelling and not sudden death.

The cause of the disease: breeder chicken infection, chicken shed infection virus, continuous chicken shed disease, high humidity and other reasons, many people think that the big pole is not well controlled, staphylococci and so on, but the effect of medication is not good.

5. Small intestinal coccidia

Because most customers are raised in nets and cages, sometimes people don't pay much attention to coccidiosis, thinking that chickens can't come into contact with feces and won't happen. This idea is wrong. Coccidiosis will occur, but it is light and heavy, and the chickens raised in the ground are relatively heavy, and sick chickens stand still. Chicken wings are drooping, feathers are disorderly, and they don't want to move around. This kind of situation is more, discharge feed-like feces, seriously discharge dark brown or red carrot-like feces, there is a pungent stench, later to the dog to do more posture, two legs forward.

The cause of the disease: generally speaking, the humidity in the house is large, and the air flow is not good, causing more, especially on the ground.

6. Vitamin or calcium and phosphorus deficiency

Generally caged for 10 days or so more, generally caused by insufficient activity, every day there are chickens, leg-lifting phenomenon, or paralysis, the femoral head is easy to break.

7. Staphylococci

Swollen legs and purple skin are the main symptoms. Foot mats, toes and surrounding tissue form spherical swelling and arthritis.

Cause: chicken staphylococcosis is a contact infectious disease caused by Staphylococcus aureus. Generally speaking, traumatic infection is secondary to infection, especially fowlpox.

Second, how to prevent and cure paralytic chickens?

1. Those caused by improper daily management

Be sure to choose a soft cushion, the length and particle size of the cushion should be appropriate (do not put the whole corn straw as a cushion), the net bottom should be adjusted smoothly for online flat and cage raising, so that the chicken can move freely and avoid rising and falling, tightening and loosening. In addition, the size of the mesh should also be suitable. Try to handle the chicken gently and don't be rude.

2. About the cause of the virus

It is an important way to prevent the occurrence of these infectious diseases by timely vaccination, keeping good hygiene in the house, ensuring that the bedding material is dry (changing the cushion material frequently) and strengthening ventilation.

3. Strengthen daily feeding and management.

Strengthen the exercise of chicks, enhance their physique, and provide high-quality calcium and phosphorus feed. At the same time, according to the actual needs, appropriate feed restriction, control of body fat accumulation, do not overweight, generally do not exceed 1.5kg, so that the growth rate of muscle tissue and bone growth rate as far as possible consistent, reasonable adjustment of feed density, ensure adequate drinking space, keep quiet, reduce stress, and timely elimination of chickens with leg disease.

To sum up, paralysis is a symptom that may occur in many diseases, and the causes of the disease are varied, caused by microorganisms, nutritional factors, improper feeding and management. there are also a variety of pathogenic microorganisms and environmental conditions caused by synergism. Therefore, in the process of diagnosis and treatment, we should find out the cause of paralysis and take cause treatment in order to achieve the goal of cure.
