How do baby goslings prevent the plague? How to treat goose plague and how to prevent and control it

Sometimes the nose drips water, saying that death is death, and there is only one left. Specialist diagnosis, if the goose eye socket is found to be blue, the eye circles are dark, the mouth is jammed, diarrhea; Although take out the goose's intestines to see if there is any food that has not been broken, cut it to see, during this period there should be like a casing, or the shape of a sausage, the shape of a sausage, if there is such a symptom, it is a goose plague, the goose's warm liver is pale yellow, the lungs are glowing, after the cut, there seems to be a layer of intestines, or like a sausage. If you find this symptom, hurry up and buy goose plague serum, 8 days later, you can prevent goose plague by buying goose plague seedlings.

Goose plague is called viral enteritis, and goose plague virus is an infectious disease caused by acute or subacute sepsis.

<> onset time is more than 3 days after the shell, the main manifestations are diarrhea, drowsiness, often lying on the ground, eating little or no food, or discarding food after eating, the bursal is soft and has a large amount of fluid, there is often discharge around the nostrils, the eyes are sunken, the feet are thin and dry, the neck is bent and bent, unable to stand, and finally the shock and death. There were also convulsions before death, and the acute course of the illness was 1 to 2 days.

Prevention and ** methods. If the goose and goose plague seedlings are vaccinated or it is not clear whether they have been vaccinated with goose plague seedlings, they should be immediately injected with goose plague anti-high serum immunization (according to 1 ml injection, or injection according to the instructions), 3 5-day-old goose plague seedlings (goose plague duck embryo attenuated strain freeze-dried vaccine), with water, muscle or subcutaneous injection. Purchase young geese from free-range farmers or relatively dispersed flocks.

It is best to inject goose seedlings with serum at the age of 2 to 3 days.

Regardless of whether the goslings are introduced in scattered or batches, they should be isolated for 7 to 10 days. Goose plague serum can also be injected during quarantine observation, but care should be taken to sterilize the needle. Chick plague vaccine can be given 10 days after injection of chick plague serum.

After such immunization, chicks can achieve effective resistance to goose plague virus and reduce the mortality rate of goose plague.

After the goose is confirmed to be infected with gosling plague, the goose without symptoms should be immediately isolated in a clean and pollution-free place for feeding, and each asymptomatic goose that is isolated is injected subcutaneously to ensure safety.

It is possible to vaccinate, once on the first day and once on 7 days, so that it is better for the body of the gosling.

Give these goslings some healthy food, drink some medicine, put them alone in an environment, and sterilize and disinfect the environment.

<> gosling plague is a virulent infectious disease that mainly affects goslings, spreading rapidly and with a high mortality rate. Gooselings, which mainly occur at 3 to 20 days of age, are the most serious infectious diseases affecting the goose industry. Let's take a look at how goose plague is.

In late July, a farmer purchased 200 2-day-old gooselings, at the age of 3 days began to get sick, 4 died of 17 at the age of 4, 70 at the age of 5 days, a total of more than 50 died, the clinical manifestations of some sick geese were depressed, weak and fell to the ground and then died suddenly;

Some sick geese shed tears, flowed water, ate little or wasted food, stood on one side, pulled yellow-green loose stools, and the course of the disease was 12 24 h. Penicillin and streptomycin ** are ineffective. Li ruler does.

1. Emergency grouping: The remaining goslings are suspected of being infected and healthy chicks are urgently grouped, and the enclosure is thoroughly disinfected with disinfectant, and the carcasses and feces are harmless.

2. Emergency vaccination: 110 living goslings were injected intramuscularly with gosling plague high immunity serum, ml, repeated intramuscular injection once every 2 days, 18 died on the 3rd day, and no death was seen afterwards. After observation, the remaining 92 goslings all recovered their health, with a ** rate of 84.

1. Do a good job of thorough disinfection of the hatchery room and its utensils and eggs, and avoid contact with the eggs and adult geese of the newly hatched goose, so as to avoid infection as soon as possible.

2. Immunization is implemented, the goose is injected intramuscularly with goose plague vaccine at the age of 1, and the gooseling at the age of 7 10 days needs to be injected intramuscularly or subcutaneously with goose plague high-free serum or high-free egg yolk liquid, only, and repeated injection once every 2 3 days at the onset of the disease; Mixing drinking water with Newcastle disease attenuated vaccine can prevent goslings from inducing chronic respiratory diseases.

3. Timely diagnosis once the disease occurs, timely grouping, disinfection, and harmless treatment of corpses and feces; Mix water with glucose at the right time to replenish nutrition and restore physical fitness as soon as possible.

Symptoms: The incubation period of goose plague virus is generally 3 to 5 days. Chicks and muscovy ducklings within 7 days of age are often infected

The prodrome is sudden death. Larger geese and muscovy ducks show mental atrophy, head shrunken, solitude, difficulty walking, and loss of appetite. Severe diarrhea, discharge of yellowish-white watery loose stools mixed with bubbles.

Increased nasal discharge, sick geese shake their heads, and fluid is thrown out of the corners of their mouths. Neurological symptoms occur near death, the neck is twisted, and the whole body has convulsions or paralysis. In general, the older the age of sick birds, the longer the course of the disease, the milder the symptoms and the lower the mortality rate.

The cloaca of diseased birds is dilated, and the nearby feathers are contaminated with thin feces. There is brown fluid coming out of the mouth and nose. The characteristic lesions are the middle and lower segments of the small intestine, especially the ileocecal and intestinal segments, which are extremely enlarged, and the intestinal lumen is filled with grayish-white or yellowish coagulation, shaped like a sausage, and often completely obstructed the intestine.

Although there is no typical coagulation in the small intestine of some sick birds, the intestinal mucosa is congested and red, which is manifested as acute catarrhal enteritis. The liver is enlarged, the spleen and pancreas are congested, and there are occasional grayish-white necrotic spots.

Eggs and incubators should be cleaned and disinfected strictly, and newly hatched chicks should not come into contact with newly harvested eggs or adult geese and muscovy ducks to prevent infection. Strengthened feeding management can reduce the mortality of sick birds.

Hong Kong Tianyu Biotech for goose plague ** program: goose plague serum antibody, subcutaneous injection of each duckling during prevention, **, each injection under 15 days of age, each injection above 15 days old, adult goose kilograms.

The goose immunization schedule is as follows:

1. Immunity of goslings:

1. Immunity of live seedlings of goslings with plague chicks. Breeding geese have not been immunized with live gosling plague seedlings, or immunized by live gosling plague seedlings but the time has been more than 100 days, the eggs hatched by such breeding geese are immunized with 1 share of live gosling plague seedlings 1 subcutaneous injection after hatching, and immunity is produced after 7 days. The eggs hatched by immunized breeding geese within 100 days of immunization have maternal antibodies, do not use live seedlings to immunize, so as not to neutralize the virus in the live seedlings with maternal antibodies, resulting in immunization failure.

2. Antiserum immunity against goose plague. In areas where there is no plague endemic in gosling, homologous (goose-based) antiserum can be used at the age of 1-7 days for young geese, and each goose can be injected subcutaneously in milliliters; In gosling-plague endemic areas, the goslings are injected with the above serum at 1-3 days of age, each injected in milliliters.

3. Goose paramyxovirus inactivated vaccine, goose influenza inactivated vaccine or goose paramyxovirus disease goose influenza double inactivated vaccine immunization. Chicks hatched from eggs laid by breeding geese that have not been immunized with single or double vaccines, or have been immunized for more than 2 months, can be injected subcutaneously at the age of 10-15 days old for single seedlings in dosage form I or double seedlings in dosage form I;

If there is a local epidemic of these two diseases, subcutaneous injection of single vaccine or double vaccine of dosage form should be carried out at 5-7 days of age. The offspring of the goose within 2 months of immunization by single or double vaccine can be immunized with single or double vaccine in dosage form I single vaccine or double vaccine in dosage form I at the age of 10-15 days.

Second, the immunization of young geese:

45-60 days after the goose goose paramyxovirus inactivated vaccine, goose influenza inactivated vaccine or goose paramyxovirus disease goose influenza double inactivated vaccine, the second single or double vaccine immunization, appropriate increase dose, each goose intramuscular injection ml. The reserve breeding goose is about 3 months old and immunized with live seedlings of goose plague breeding goose for 1 time, and injected according to the conventional amount.

III. Immunity of Adult Geese:

1. 15 days before the goose flock lays eggs, intramuscular injection of goose egg plague inactivated seedlings or goose egg plague avian Pasteurella double inactivated vaccines immunization.

2. About 10 days before the goose flock lays eggs, inject the No. 1 dosage form goose paramyxovirus inactivated vaccine, goose influenza inactivated vaccine or dual vaccine into the other side intramuscularly, inject 1 ml into each goose, and inject it again once after 2 months.

3. Immunize goose plague seedlings about 5 days before the goose flock lays eggs, if the goose has been immunized, the second immunization can be carried out with the conventional 4 5 times the dose, and the immunization period can reach 4-5 months; If the goose has not been immunized, it will be immunized according to the conventional amount, and the immunization period is 100 days. 1 more dose of 2-5 pigeons within 100-120 days after immunization.

The use of goose vaccine should be carried out according to the specific local situation, and what are the frequent infectious diseases in the local area, which should be prevented in time. Among them, the more common is the goose plague, its preventive measures are: if it is determined that the breeding mother goose has not been vaccinated with the goose plague vaccine 30 days before laying eggs, then 5 days after the goose hatches 7 days, the goose plague vaccine or goose plague high immunity serum.

Ten days after the goose plague serum injection, the goose plague vaccine is also administered. Because the protection period of goose plague serum is short, the goose plague vaccine must be injected again after 10 days of injection to prevent the occurrence of goose plague The role of serum: serum is often used for the corresponding epidemic ** or emergency prevention process.

When injecting serum, it should be noted that it must be injected in strict accordance with the instructions, grasp the injection dosage and method in detail, and pay attention to grasping and putting it gently, and observe whether there is any abnormal reaction after injection.

Goose immunization program: 3-day-old injection of goslings with high free serum 0 3 0 5ml feathers. 7 10 days old, inject influenza oil vaccine 0 3 0 5 ml feathers.

At 21 days of age, 1 head of goose plague vaccine was injected. At 35 days of age, 2 ml of Pasteurella goose vaccine was injected. At 22 weeks of age, 1 part of the goose plague vaccine was injected.

At 23 weeks of age, inject 0 5 ml of influenza oil seedlings. At 24 weeks of age, inject 1 ml of E. coli seedlings. Repeat again at 22-24 weeks of age at the beginning of labor.

<> gosling plague is an acute septicaemic infectious disease caused by gosling plague virus, which mainly affects goslings under 20 days of age, with a fatality rate of more than 90%. This article introduces the emergency prevention and control measures and immune prevention methods of goose plague for reference.

The sick goose is isolated and alone, the hair is loose and the neck is shrunk, the eyes are closed and drowsy, the severe non-eating, yellow-green loose stools, filthy secretions adhered around the nostrils, and the nervous symptoms such as neck twisting, leg paralysis or convulsions occur before death.

Characteristic gastrointestinal lesions were seen on autopsy, and there was a yellowish-white banded pseudomembrane in the middle and lower intestinal lumen of the small intestine, which blocked the intestinal lumen and formed an embolic substance, with a solid texture and a sausage-like shape, and the sausage-like material was very obvious in subacute cases.

Once the gosling plague occurs in the gosling flock, the goslings without symptoms will be isolated immediately, and each chick will be injected subcutaneously with high-potency antiserum or 1 egg yolk antibody, and broad-spectrum antibiotics can be appropriately added to the antiserum or yolk antibody.

At the same time, each sick goose was injected with 1ml of high-potency antiserum or 2ml of yolk antibody subcutaneously, and 1ml of antiserum or 2ml of yolk antibody could be injected into each 500 grams of body weight for the diseased goose.

1. Immunity of breeding geese.

If live vaccines are used, there are two methods of immunization.

One-time immunization method: about 15 days before the breeding goose lays eggs, 1 100 times diluted goose embryo weakened goose weak poisonous seedlings (referred to as goose seedlings, the same below) 1ml subcutaneous or hungry intramuscular injection.

At 12 to 120 days after immunization, the eggs hatched by breeding geese were resistant to gosling plague virus infection, and after 120 days, the protection rate of the goslings decreased, and they had to be immunized again.

Secondary immunization method: 1 month before egg laying with 1 100 times diluted goose seedlings 1ml for immunization, 15 days before egg laying with 1 10 times diluted goose seedlings 1ml for immunization, the protection rate of offspring goslings can be 5 months after immunization.

2. Immunization of goslings.

For goslings without maternal antibodies, or the offspring of breeding geese after 100 days of immunization with live gosling plague seedlings, they can be immunized subcutaneously with live gosling plague seedlings at the age of 1 2 days.

After immunization, it must be isolated for 7 days to prevent infection with the virus. Goslings with maternal antibodies should not be immunized with live seedlings.

3. Precautions for trembling limb pins.

Goose plague is mainly transmitted through hatcheries, so hatcheries should be disinfected in all aspects. After the occurrence of this disease, the incubation should be stopped immediately, and the whole field should be thoroughly disinfected before re-incubation.

Pro, the epidemic prevention process of raising geese is as follows: 1. Subcutaneous injection of goose special gosling plague live vaccine within 24 hours of leaving the kang for the prevention of goose plague 2-day-old oral immunization with goose new viral enteritis attenuated vaccine to prevent goose new viral enteritis 7-day-old subcutaneous injection with new tributary collapse triple seedling of chickens to prevent goose paramyxovirus and bronchitis avian influenza 12-day-old duck plague vaccine 10 pieces, subcutaneous injection to prevent goose and duck plague 17-day-old chicken Newcastle disease seedlings 5 times the amount of drinking water to prevent goose paramyxovirus 25-day-old avian influenza H51ml to prevent avian influenza Poultry cholera vaccine to prevent goose cholera disease 35-day-old duck plague vaccine 15 20 birds to prevent goose and duck plague. In order to ensure the safety of meat, no oil or aluminum hydroxide adjuvant vaccine should be given 6 weeks before returning to the city or slaughtering.
