List of drugs for the prevention and treatment of chicken diseases, prevention and treatment of comm

List of drugs for the prevention and control of chicken diseases:

1. Newcastle disease in chickens, 1. Symptoms.

1) Sick chickens open their mouths to breathe, their heads and necks are straightened, and they make snoring sounds, accompanied by conjunctivitis and sinusitis, and the clinical manifestations are cough and runny nose.

2) The sick chickens were gradually dehydrated and emaciated, excreting watery green feces, and showing chronic sporadic death. 2. Prevention and control.

1) Feed each adult chicken 4-5 tablets of Qingwen septic tablets in 2 times and use them continuously for 3-5 days.

2) Mix 300 grams of Yinqiao powder (half the amount of chicks) in the feed of 100 adult chickens, and use it continuously for 3-5 days.

2. Chicken coccidiosis.

1. Symptoms, 1) The sick chicken is depressed, the appetite decreases, the bursa is filled with fluid, the comb is pale, and the chicken is gradually emaciated.

2) The stool is purple-brown in the early stage of the disease, and turns into bloody feces in the later stage, and contains mucus and shedding intestinal mucosa.

2. Prevention and control, 1) The mixture uses chlorphenidine, with a dosage of 60-66 mg kg of body weight, and is used continuously for 3-7 days.

2) Nibenzamide (Ball dysentery) is used in the mixture, and the dosage is 250-300 mg kg body weight, and it is used continuously for 3-5 days.

Common chicken diseases mainly include infectious bronchitis, escherichia coli, chick dysentery, etc. Infectious bronchitis will cause chickens to roar and cough at night, E. coli disease will cause chickens to stand still and reduce feed intake, and chick dysentery will cause diarrhea, lethargy, and listlessness, which must be prevented and treated with drugs in time.

1. Infectious bronchitis

Infectious bronchitis is one of the most difficult diseases to prevent, without any precursor symptoms, the chickens are sick almost simultaneously overnight, tears, swelling of the face, coughing, sneezing, obvious roaring and coughing at night, and death after severe disease, which needs to be carried out in time with Wan Hu Ning, Hu Du Kang, etc. **.

2. Escherichia coliform disease

Escherichia coli disease is a disease of the digestive tract, the diseased chickens will have obvious lack of energy, reduced feed intake or even not eating or drinking at all, scattered crouching and not moving, the crown of the head is blue and purple, can not stand and walk, it is necessary to use a special E. coli rod in time to mix food or water treatment to let it eat.

3. Chick dysentery

Most of the chicks who suffer from this disease will die in about 7 days or so under this disease, which is manifested as piles and piles crowded in a corner, wings drooping and listless, sleeping all day long, and the excreted feces are white, which should be treated with drugs such as intestinal rod Ning for ** and prevention.

4. Sanitary conditions

Whether it is infectious bronchitis or colibacillosis or chick dysentery, the crux of the crux is the unhygienic breeding environment, there are a large number of pathogenic bacteria and pests in the environment, and even spread to the trough and sink, which will cause this situation.

Commonly used drugs for raising chickens are anthelmintics, oxytetracycline, penicillin, streptomycin, chloramphenicol, etc.

1. Deworming drugs.

Albendazole ivermectin, mostly used for deworming (in vitro and extracorporeal parasites) at the age of 60 days and 120 days old in chickens; Coccidiosis drugs such as sulfachlorazine sodium and diccozulil are used for prevention under 90 days of age.

2. Oxytetracycline.

According to the proportion of feed feeding, it is used for 5-7 days, mixed into the feed and used to prevent and treat infectious laryngotracheitis, infectious bronchitis, colibacillosis, white dysentery, infectious osteoarthritis, paratyphoid fever and other diseases. It can also be drunk according to the proportion of orange digging water. It should be noted that there are contraindications to the combination of erythromycin and sodium bicarbonate, and when the dose is too large, it is easy to affect the hatchability.

3. Penicillin.

2000-3000 IU of penicillin per chicken was added to drinking water for 3-5 days; Or intramuscular injection, each chicken is injected with 50,000 IU to prevent and treat chicken dysentery, paratyphoid, infectious osteoarthritis, coccidiosis, etc. If you add it to water, you need to let the chicken drink it within 2 hours. It should be noted that it is contraindicated with acidic drugs such as tetramycin and sulfonamides.

4. Streptomycin.

According to the proportion, it is mixed into drinking water and used for 3-5 days to prevent and control mycoplasmosis, rhinitis, cholera, chicken tuberculosis and colibacillosis. Attention should be paid to the use of young birds and exotic purebred poultry with caution.

5. Chloramphenicol.

Dose of grams per kg of body weight, 3 times a day; or 20-50mg per kg of body weight intramuscularly injection, twice a day, to prevent and treat chicken typhoid, white dysentery, and paratyphoid.

Prevention of chicken rhinitis with**.

Veterinary Drug Investment Network:

Chicken rhinitis is caused by the bacterium Haemophilus chicken.

Haemophilus fowlis is pleomorphic. At the time of initial isolation, it is a gram-negative micrococcus, stained at both poles, does not form spores, has no capsule, no flagella, and cannot move. The thallus is first rod-shaped or club-shaped, and has a tendency to filament.

It then degenerates with fragments and irregular morphology, at which point moving it to fresh medium returns to its typical rod or ball stick state.

Chicken rhinitis occurs in chickens of all ages, and the infection of elderly chickens is more serious. Pheasants, pearl chickens, and quails can also develop diseases occasionally, but the nature of the disease is different from that of chickens and has a toxic reaction.

Symptoms of chicken rhinitis:

Lesions that cause inflammation of the nasal cavity and sinuses often present only with a thin nasal discharge of clear fluid, which first flows from the nostrils and then turns into a serous viscous discharge, sometimes sneezing. The face is swollen or shows edema, conjunctivitis, swollen eyelids. Loss of appetite and water intake, or diarrhea and weight loss.

The sick chicken is depressed, free from edema, shrinking its head, and standing still. Poor growth of chicks and reduced egg production in adult hens; Rooster beard is often swollen. If the inflammation spreads to the lower respiratory tract, it is difficult to breathe, and the sick chicken often shakes its head to expel the mucus in the respiratory tract, and there are rales.

The throat may also have clots with secretions. These are typical symptoms.

Because the symptoms of chicken rhinitis are similar to chronic respiratory diseases, chronic chicken cholera, avian pox, and vitamin deficiencies, it is difficult to diagnose and is prone to infection.

Chicken rhinitis has a high incidence and low mortality rate, but it is easy to die from secondary diseases, such as chronic respiratory diseases in chickens, chicken colibacillosis, chicken dysentery, etc.

There are fewer morbidity and mortality in rearing chickens, and there are fewer deaths in the late epidemic period than in laying hens. The main lesions are acute catarrhal inflammation of the nasal cavity and sinus mucosa, the mucosa is congested and swollen, the surface is covered with a large amount of mucus, and there is an exudate clot in the sinus, which later becomes a caseous necrosis. Catarrhal conjunctivitis is common, with conjunctival hyperemia and swelling.

Subcutaneous edema of the face and flesh. In severe cases, inflammation of the tracheal mucosa may be seen, and occasionally pneumonia and balloonitis may occur.

Prevention of chicken rhinitis:

1. Heating equipment and automatic control ventilation devices should be installed, which can significantly reduce the concentration of ammonia in the chicken house.

2. By taking chickens to disinfect and reduce the dust in the air and purify the air, it has played a positive role in the prevention and control of this disease.

3. Strengthening the cleaning and disinfection of drinking water utensils and drinking water is a regular measure for disease prevention.

4. The staff of the chicken farm should strictly implement the epidemic prevention system such as changing clothes, bathing, and changing shoes. When it is necessary for multiple people to enter the house due to work needs, the chickens will be disinfected immediately after the work is completed.

5 Chicken coops, especially sick ones, are a large polluted place, so great attention must be paid to cleaning and disinfection of chicken coops.

The disinfection of the outside environment of the chicken coop and the removal of weeds and dirt should also be neglected. Therefore, comprehensive prevention and control is an indispensable and important measure to prevent the occurrence of this disease.
