How to prevent duck plague? How adult ducks protect against the plague

Clinical symptoms] sick ducks show depression, tears, eyelid edema, moist feathers around the eyelids are wet circles, some sick ducks head subcutaneous edema, head and neck swelling, so commonly known as "big head plague". Most of the sick ducks showed severe diarrhea and had grayish-white or green, watery loose stools. [Symptoms of autopsy] autopsy showed esophageal mucosal hemorrhage, yellow pseudomembrane formed on the surface of the larynx and esophageal mucosa, coronary fatty hemorrhage, intestinal mucosal congestion, hemorrhage, necrosis or ulceration, and button-shaped necrosis foci formed at the intestinal lymphatic collection tissue.

There are grayish-white necrotic foci and hemorrhage of different sizes on the surface of the liver, and the hemorrhage occurs in or around the necrotic foci**, and some necrotic foci are red by hemorrhage. [Precautionary measures] Before entering the duck, the duck house and the site are disinfected with 3% caustic soda water or 5% formaldehyde solution and 10% bleach powder suspension. In the future, it should be disinfected frequently, and it can also be disinfected (200 grams per package) to 240 kg of water, and the duck flock and feeding pond should be sprayed on a plane once every half a month.

To implement the self-breeding and self-raising system, the eggs or ducks that need to be introduced must come from non-epidemic areas, and they must be transported to prevent poisoning or infection.

Regular injection of duck plague vaccine, the specific usage and dosage are strictly in accordance with the instructions of the vaccine, usually diluted with normal saline, and the multiple can be determined according to the injection amount of each animal. For example, ducklings (within 1 month of age) can be diluted 40 times, each duck is injected intramuscularly with milliliters, and the immunization period is 1 month; 2-month-old ducks can be diluted 100 times, each intramuscular injection of milliliters, immunization period of 5 months; Ducks over 5 months old can be diluted 200 times, each intramuscular injection of 1 ml, immunization period of 6 to 9 months. The immunization program should be formulated according to local conditions, according to whether there is an epidemic in the region and the situation of the duck flock.

Once the duck is born, the epidemic should be reported in a timely manner, the scope of the epidemic area should be delineated, and the strict blockade, isolation, incineration, deep burial of dead ducks, disinfection and other work should be carried out quickly, and at the same time, the hypothetical healthy duck immediately take a large dose of duck plague attenuated vaccine emergency vaccination: 20 times the amount of heavy, 15 times the amount of light, and the mortality rate can be significantly reduced within 1 week after general vaccination, which is a strong measure to control and eliminate the duck plague epidemic. The disease focuses on prevention, and is only an auxiliary method.

It can be used to resist duck plague and high immunity serum for early **, each intramuscular injection of milliliters, and polymyocytes (a kind of endogenous interferon), each adult duck can be injected intramuscularly 1 milliliter, once a day, and used 2 or 3 times, can receive certain curative effects.

Adjuvant with Chinese medicine**: a15 grams of gall grass and wood fragrance, 10 grams of Coptis chinensis, 10 grams of barberry, gardenia, Yin Chen, rhubarb, 6 grams of citrus aurantium, 5 grams of licorice, woody grinding juice or soaking for 1 day, other medicines boiled for 10 minutes to remove slag, and the soaked rice can be fed to 50 sick ducks.

b.Feed sick ducks with soft-shelled turtle insects, 1 time per duck (broad bean-sized soft-shelled turtle insects), 3 times a day, and use for 3 consecutive days.

Duck plague, commonly known as "big-headed plague", is an acute septicaemic infectious disease of ducks caused by a virus. It can occur all year round, but is generally most prevalent in spring and summer and autumn. It is more common in laying females and adult ducks, and the mortality rate is more than 90%.

The characteristic symptoms of sick ducks are swollen head and neck, tearing and closed eyelids, weak feet and inability to stand, discharge of green loose feces, cloaca congestion, hemorrhage, edema, and even mucosal ectropion. Autopsy showed that the mucosa of the esophagus and cloaca was covered with a yellow-brown pseudomembrane, and there were grayish-white necrotic spots the size of pinheads or rice grains on the surface of the liver, small bleeding spots in the middle of the necrotic points, or annular bleeding bands on the periphery, and bleeding between the esophagus and the glandular stomach.

Prevention and control measures] 1) Usually the duck farm should strengthen the disinfection work, do not buy ducks from the epidemic area, and refuse to visit. The most important thing is to use duck plague duck embryo attenuated vaccine for artificial active immunization. After the ducklings were inoculated, the immunization period was 6 months; After the adult duck is inoculated, the immunization period can be up to one year.

Inoculation is generally carried out during the shutdown of the female ducks, and the new female ducks can be vaccinated one month before laying eggs.

2) At present, there is no specific drug for duck plague**. After the outbreak of duck plague, isolation and disinfection should be strengthened first, and then emergency vaccination with duck plague vaccine. The dosage of the vaccine is usually 3 to 5 times the amount of prophylaxis, and the hypothetical healthy duck should be injected first, and the injection should be replaced by a sterilized needle.

3) Sick and dead ducks should be buried deeply, and it is strictly forbidden to transfer sick ducks or **, stop grazing, and prevent poisoning; Thoroughly disinfect the duck house, grounds, utensils, etc., and wait for 1 to 2 months before use.

In this case, the most important thing we should do is to carry out a simple isolation treatment first, and then spray some disinfectant water, simply clean up the surrounding environment, and isolate some ducks that are not infected.

1. In areas where duck plague is endemic or threatened, duck plague and duck embryo attenuated vaccine immunization should be carried out according to the immunization program. The immunization period can be up to 6 months after vaccination for ducklings and up to 1 year for adult ducklings. 2. Once the duck plague is found, quickly isolate the sick ducks, suspected sick ducks and presumed healthy ducks, and carry out emergency vaccination against the last two groups of ducks, usually 1 week after vaccination, the epidemic can be stopped.

For sick ducks in the early stage of infection, anti-duck plague high immunity serum can be injected intramuscularly, and 1 2 ml per duck can be injected.

In addition to biosecurity measures, the use of attenuated live vaccination against duck plague can effectively prevent the occurrence of this disease. Note that it is strictly forbidden to introduce breeding ducks and duck seedlings from epidemic areas.

The first thing is to ensure the safety of the inside of this venue, and it must be ventilated in time, and the garbage in this place must be removed and cleaned out, and these ducks must be vaccinated in time.

Under normal circumstances, the duck house should be disinfected, ventilated, and feed management should be strengthened, and the ducks should be vaccinated if conditions permit, and "cyst Wenkang" or "Du Luo" should be added to the feed regularly during the susceptible period of disease to improve the body's immunity.

We first have to clean and ventilate the duck house, and then spray it with disinfectant every day for 4 weeks.

It is important to keep your teeth clean and tidy, and pay special attention to disinfection, and ventilate while maintaining temperature.

Summary. Once duck plague occurs, immediately isolate the sick duck, and strictly sanitize all items and water sources that come into contact to avoid contact infection of other ducks. Emergency vaccination of ducks can double the dose and reduce the rate of duck disease.

Antibiotics and sulfonamides have no effect on the disease, but for mild ducks, interferon or anti-duck plague serum is used. The virus is not resistant to the external environment and can be sanitized with general disinfectants in the external environment. The first point of duck plague in the farm is to isolate and sanitize to prevent further infection.

For the value of the sick duck can be symptomatic, the value of the duck should be harmless, this point needs to be noted.

I am a duck farmer, and recently my laying ducks have had a few duck plagues, now what should I do.

To be timely, there is a specific plan sent above, you refer to it.

What disinfectant solution is better.

Chlorine dioxide is best used for liquids, but ozone works best. Disinfection mainly uses 84, quicklime, plus some peracetic acid, hydrogen peroxide, potassium permanganate, etc.

How to disinfect the water fed to the ducks.

Disinfection methods of drinking water The disinfection methods of drinking water include boiling disinfection, ultraviolet disinfection, ultrasonic disinfection, magnetic field disinfection, electronic disinfection and other physical methods and chemical disinfection methods. Chemical disinfection is a common method for disinfection of drinking water in farms.

Chlorine dioxide is also fine.

Now there are about 5 sick ducks in the duck farm, and I have isolated them, is this duck plague contagious?

If you isolate it, you won't be contagious on a large scale.

We're going to give the ducks antibodies tomorrow, can we prevent it?

OK. Is there a high probability of mass infection? In my current situation.

It shouldn't be, because you are isolated in time, and then disinfect and disinfect, and you can play antibodies.

Strengthen daily cleaning, sanitation and disinfection work, and do a good job in environmental sanitation. Good hygiene is one of the most effective ways to reduce transmission and cut off the routes of transmission. Therefore, around the duck farm and in the duck farm should be cleaned and disinfected regularly to ensure that there are no weeds, rotten wood, dead ducks, sundries, etc.; The aisles, curtains, troughs, and water troughs in the duck house should be kept clean and hygienic; Prevention and treatment at the age of 2 months of duck plague vaccine, generally within 1 week to produce strong immunity, the early stage of the disease intramuscular injection of anti-duck plague high immunity serum, per duck injection ml, has a certain curative effect.

Adult ducks were injected 1 mg of polymuscular cells intramuscularly once, once for 3 days, 2 8 times had a good curative effect.

Strengthen feeding management and improve the disease resistance of ducks Good feeding management can effectively improve the disease resistance of broiler ducks and laying ducks. For example, providing nutritious and comprehensive feed to the duck flock can effectively improve the immunity of the duck; Clean drinking water can avoid a variety of bacterial diseases in ducks; 1. Duck infectious serositis mainly affects ducks aged 1 8 weeks, among which ducklings aged 2 to 3 weeks are the most susceptible to infection, especially in late autumn and winter and spring. Symptoms:

The most acute patients could not see the symptoms, and Liang Rangjie died suddenly. The main clinical manifestations of acute cases are depression, lack of food, refusal to eat, and dyspnea. The most easily observed is the greenish, thin color of the stool.

Sick duck species need to be fed with enrofloxacin with feed, knowing that the situation is improving. Other ducks should be stirred and fed with penicillin to avoid infection. The second epidemic disease, generally caused by improper management of respiratory tract infections from drinking water and feed.

The third Escherichia coli, Globulus oakworm enteritis virus disease, ** Medication: quinolone type drugs, breeding ducks to do epidemic prevention work in advance, duck farms are cleaned frequently.

It is necessary to strengthen the management of feeding, improve the disease resistance of the duck flock, clean the duck house frequently, keep the duck house clean and hygienic, and prevent bacteria from having a place to hide. In addition, the feeding of the ducks to the brand is guaranteed, combined with corn and other coarse grains, to achieve a fine match. Observe the performance of the duck flock If you notice symptoms of illness in the flock, promptly consult a veterinarian for diagnosis.

If the duck flock is confirmed to have bacterial infectious diseases such as avian cholera, E. coli, salmonella, etc., the sick duck should be isolated and <>
