Chicken knowledge: Why does it cause paralysis of chickens? How to prevent it?

1. Why does it cause paralysis chicken?

1. Enterotoxic syndrome

It usually occurs frequently between 10-20 days. It is susceptible to panic groups, paralyzed legs, lying on the stomach, large head, head trembling, not because the legs cannot stand, the toxins are absorbed by the broiler, causing paralysis. It’s like people drink too much, reduce appetite, fried hair, in severe cases, the feces become white and thin, not formed, there is undigested feed in the feces, and some have "tomato"-like loose stools and "fish intestines"-like feces, dying The former chicken ran wild, screamed, and fell to the ground paralyzed to death. Causes of disease: virus infection, Clostridium weichii, intestinal coccidia, mycotoxins, etc.

2. Atypical Newcastle Disease in Broilers

Broilers usually get onset after 25 days of age. They often have mild respiratory symptoms in the early stage. Those with a longer course of disease may have croaking, nasal fluttering, strange barking, etc., chickens have enlarged crops, and often drip on the trough when they lower their heads to feed.

There is also a soft neck and paralysis. It is not the cause of the legs, but the nerve damage caused by the Newcastle disease virus. In the middle stage, the chickens are sluggish, unwilling to act, take two steps in one step, paralysis on one leg, weight loss, dark red breasts of broilers, yellow-green loose stools, and nerve symptoms such as turning necks and necks in later stages. Causes of disease: Immunization procedures are not in place, many do not make oil vaccines, and do not drink water for 21 days for immunization, resulting in low antibodies in the later stage, causing diseases, or drinking water immunity pipelines are not clean, etc.

3. Escherichia coli (arthritis)

Broiler chickens usually occur in young chickens or later concurrent with E. coli sepsis. The chickens have loose feathers, are afraid of the cold and get together, thin and stand alone; they discharge gray and white dung, pollute white feces around the anus; drooping wings, numb and swollen joints, difficult to stand up . In many cases walking on one leg, Salmonella can also experience this situation. In the later stage, symptoms of pericardium and liver, joint disorders, and white rice soup with green loose stools in the middle. Causes of disease: chicks are generally related to breeders, hatching pollution, etc. There are big factors, and there are some reasons for the sensitivity of opening drugs. Large chickens generally have more concurrent infections.

4. Viral arthritis

The disease mostly occurs in broilers at 3-4 weeks. The chicks are infected, but not necessarily the disease, and the diseased chickens spread quickly through contact. It is prone to continuous batches of excessive humidity in the early stage, severe disease, severe paralysis, joint swelling and dark red, not sudden death.

Causes of disease: breeder infection, virus infection in chicken sheds, continuous disease in chicken sheds, high humidity and other reasons. Many people think that large rods are not well controlled, staphylococcus, etc., but the effect of medication is not good.

5. Small intestine coccidia

Because most of the customers are raised in nets and cages, sometimes people don’t pay much attention to coccidia. They think that chickens cannot touch feces and will not happen. This concept is wrong. Coccidia will happen. Raising chickens is relatively heavy, sick chickens stand stubbornly, chicken wings are drooping, feathers are scattered, and they don't want to walk around. This kind of situation is more common, the discharge of feed-like feces, the severe ones discharge dark brown or red carrot-like feces, with a pungent stench, and the dog is more posture in the later period, with both legs forward.

Causes of disease: Generally, the humidity in the house is high, and the air flow is not good, causing more causes, especially the ground breeding.

6. Insufficient vitamins or calcium and phosphorus

Generally, it occurs more frequently in cages for about 10 days, and it is usually caused by insufficient activity. Chickens, leg skipping, or paralysis and femoral heads are easily broken every day.

7. Staphylococcus

Swelling of the legs and purple skin are the main symptoms. The foot pads, toes and surrounding tissues form spherical swelling, resulting in arthritis.

Cause of disease: Chicken Staphylococcus disease is a contact infectious disease caused by Staphylococcus aureus. Generally, there are more secondary traumatic infections, especially chicken pox.

2. How to prevent paralyzed chickens?

1. About improper daily management

Be sure to choose a soft bedding, the length and granularity of the bedding release should be appropriate (do not put the whole corn stalks as bedding), and the bottom of the net should be leveled for online flat and cage breeding, so that the chickens can move freely. Avoid sudden high and low, sudden tight and loose, and the size of the mesh should also be appropriate. Catch chickens as much as possible, and don't be rough.

2. About the virus

Immunization must be timely, keeping good hygiene in the house, ensuring dry bedding (changing bedding frequently), and strengthening ventilation are important ways to prevent the occurrence of these infectious diseases.

3. Strengthen daily feeding management

Strengthen the exercise of the chicks, strengthen the physical fitness, and provide high-quality calcium and phosphorus source feed. At the same time, appropriately restrict feeding according to actual needs, control body fat accumulation, and prevent excessive body weight, generally not exceeding 1.5kg, so that the growth rate of muscle tissue and the growth rate of bones are as consistent as possible, and the feed density is reasonably adjusted to ensure sufficient drinking water. Space, keep quiet, reduce stress, and eliminate chickens found to have leg problems in time.

In summary, paralysis is a symptom that may occur in many diseases, and the causes of the disease are various, including microbial disease, nutritional factors, and improper feeding and management. , There are also a variety of pathogenic microorganisms and environmental conditions caused by the synergistic effect. Therefore, in the process of diagnosis and treatment, we must find out the cause of the paralysis and take corrective treatment to achieve the goal of cure.
