What are some common symptoms of chicken disease? How to prevent it?

Chicken farming is very common in rural areas, and now large-scale farming is adopted in many places to save manpower and material resources. However, if the breeding scale is large, it is more worried about the occurrence of the disease. Once infected, it may affect all of them. Let's take a look at some common symptoms of chicken disease. How to prevent it?

What are the symptoms of some common diseases of chicken disease?

1. Infectious bursal disease

At present, the disease has become one of the major infectious diseases that seriously harm the chicken industry. The injury of bursa of Fabricius leads to immunosuppression, resulting in immune failure such as Marek's disease and Newcastle disease, and is more likely to be co-infected with colibacillosis, salmonellosis, coccidiosis, aspergillosis, Newcastle disease and chronic respiratory diseases, resulting in increased mortality and even total elimination of chickens, making treatment more difficult.

The high incidence period of the disease is from April to June, and it has the characteristics of wide range of age, long course of disease, and immune chickens can still develop the disease. At the beginning of the disease, depressed spirit, fluffy feathers, drooping wings, trembling, decreased food intake, closed eyes and napping, which could affect the whole group in 1-2 days; increased drinking water, some pecked anus, white or watery sparse feces, dehydration, lying on the ground, extremely weak, and finally died. Tolerated anaemia, emaciation and slow growth of chicks.

2. Infectious bronchitis

The main clinical manifestations of diseased chickens were dyspnea, sneezing, depression, eye closure and diarrhea. Chicken crown, meat beard red, swollen, sometimes coughing and breathing rales. Autopsy showed yellow-white mucus in bronchi and bronchioles, serious yellow-white cheese, varying degrees of renal swelling, spotted kidney, and urate deposition; pneumonitis, peritonitis; follicular and fallopian tube congestion and bleeding. If there is no emergency use of effective drugs, there will be pericardium, liver, and high mortality.

3. Colibacillosis

Colibacillosis has become one of the main bacterial diseases harmful to chicken flocks. In practice, colibacillosis is often mixed with mycoplasma disease, Newcastle disease, avian influenza, coccidiosis, infectious bronchitis and other diseases, resulting in more difficult treatment and increased mortality. The most common clinical symptoms are depression, reduced or non-feeding, isolated or crouching, bluish-purple beard, gray-white iris, decreased vision or blindness, loose feathers, feces around the anus, green or yellowish-white thin feces, crouching, inability to stand, reluctance to move or claudication, joint enlargement, hepatomegaly, intestinal mucosal bleeding and ulcers, pericardial inflammation, ascites and yolk in the abdominal cavity. Symptoms such as paw dryness and dehydration.

Second, how to prevent common diseases in chickens?

1. Make a perfect culture plan.

In the process of breeding, breeders should formulate a sound breeding plan, regularly and regularly do the corresponding disinfection and cleaning of chicken sheds, utensils, and the surrounding environment, and do a good job in vaccination of chickens on time, so as to improve the resistance of chickens and reduce the incidence of disease in chickens.

2. Improve infrastructure construction

In order to ensure the healthy growth of chickens, we first need to provide a comfortable and healthy breeding environment. Therefore, in the process of breeding, we should constantly improve the infrastructure to ensure that chickens are in a good growing environment at all times. Specifically, we can do it from the following aspects: first, breeders should maximize the hygiene of chicken sheds and disinfect them regularly and regularly, so as to effectively reduce the possibility of man-made transmission of diseases. Second, we should establish a reasonable immunization procedure according to the growth cycle of the flock to ensure the healthy growth of the flock. Third, we should do a good job in intensive inspection and inspection. Once abnormal phenomena are found in the flock, such as listlessness, abnormal stool and so on, the breeders should consult the professional veterinarian in time. Fourth, after we found sick chickens, we should be quarantined at the first time, so as to avoid infecting healthy chickens.

3. To ensure the effect and accuracy of chicken medicine.

When buying chicken medicine, farmers must remember not to buy some drugs with low price and poor effect in order to reduce the cost. At the same time, in the use of medicine, must be strictly in accordance with the instructions for treatment, even after the use of medicine, sick chickens did not significantly improve, we should not blindly increase the dose, because the treatment of diseased chickens need a certain amount of time, blindly increase the dose, it is easy to lead to adverse reactions. Therefore, we should maximize the effect of chicken medicine and the accuracy of drug use to avoid unnecessary economic losses.
