- this is always a big problem even for experienced poultry farmers. Diseases always greatly reduce the number of livestock and cause very serious economic and ethical harm. All poultry farmers know that it is much easier to prevent a disease than to treat it later.

Goose disease prevention should be carried out regularly in poultry houses. The most important thing is to inspect the entire population of geese every day and, if the slightest symptoms of the disease appear, immediately limit the sick bird from the general herd! It is timely isolation that will allow for the successful treatment of sick birds and timely conduct of veterinary and sanitary measures in the general herd.

Symptoms of goose disease

The main symptoms that indicate that your bird is sick can be: food refusal, lameness, frequent swallowing movements, convulsions. All these signs should alert the poultry farmer. As mentioned earlier, with these symptoms, you should immediately isolate the goose from the herd. This is due to the fact that if the disease is infectious, then it will immediately be transmitted to other winged relatives. After isolation, you should make a rough diagnosis (common goose diseases are below). In this case, you need to pay close attention to the neck, head, limbs, plumage (maybe the bird just got hurt, and did not get sick with an infectious disease).

The main diseases of geese and their treatment

• Neisseriosis. Ganders are most susceptible to this disease. Symptoms: inflammation of the penis. After this disease, geese become completely barren. The cause of the disease most likely lies in the poor condition of the content: dirty bedding, poor food. If this disease is detected, sick birds are allowed to enter, and antibiotics are administered to healthy ones. Everything in the room should be disinfected.
• Amidostomatosis. Infection with this unpleasant disease occurs after the goose swallows pathogen larvae with food or grass. A sick bird loses a lot of weight. This disease should be treated with carbon tetrachloride, the dose for an adult goose is 5-8 ml.
• Hymenolepiasis. Geese get sick with this disease after swallowing mollusks or other water insects from a reservoir. Massively, birds become ill with this after being released onto water bodies. Symptoms: paralysis of some limbs, convulsions, very unsteady gait, the bird is always tired.

Often, geese get sick due to another disease called beriberi. Symptoms of beriberi: impaired coordination of movements, the birds are sluggish all the time. In the prevention of beriberi in geese, it is necessary to include constant walks on fresh air, the diet should include bone meal, fish oil, chalk.

Knowing these diseases of geese, you now know how to treat the bird, as well as how to prevent these diseases.

Content:

The goose is an unpretentious, hardy bird, able to use the pasture well with a minimum of concentrates. However, for this to happen, the goslings must grow up, get stronger. Like other chicks, the well-being and life of goslings depends on the formation of the body's immune defenses, which can weaken due to hypothermia and overheating, dampness or dryness, drafts, poor nutrition and other factors. The poultry farmer must understand that all diseases of geese are divided into contagious and non-infectious.

This article will introduce beginner poultry farmers to the dangers that await when raising geese. What problems they can handle on their own, in what situations you need to call a veterinarian as soon as possible, and also how to prevent future troubles.

contagious diseases

There are the following contagious diseases of geese:

• parvovirus enteritis;
• colibacillosis;
• salmonellosis;
• pasteurellosis;
• aspergillosis;
• coccidiosis;
• infectious cloacitis;
• worms.

Parvovirus enteritis

Goslings 1–3 weeks old are susceptible. Recovered geese become lifelong virus carriers. Unfavorable zoohygienic conditions contribute to the development of the disease and its spread. The disease affects domestic geese in early spring. The disease is transmitted mainly from an infected mother, characterized by conjunctivitis, nasal discharge. There is diarrhea in goslings with films or blood. Every third patient dies. In those who have recovered, the stomach sags, their development slows down. Goslings cling to each other, they develop dermatitis, feathers fall out on their backs.

It is important in a timely manner, according to the symptoms, to recognize the cause of the disease of geese and prescribe treatment. A specific serum administered subcutaneously is used, nitrofurans and antibiotics are used to suppress secondary microflora, for example, Furazolidone, Baytril, Tetracyclines. For prophylactic purposes, goslings are immunized in the first days of life. Revaccination is carried out in 3-4 weeks.

Goslings of the first month of life are ill, mainly. This period is dangerous for chicks of other species by the threat of white diarrhea, which is caused by salmonella. The disease, if spread, is difficult to cure, it can destroy the entire goose population. There are the following factors that provoke the occurrence of salmonellosis:

• overheating of goslings;
• crowded content;
• avitaminosis with unsatisfactory nutrition.

The causative agent is introduced by rodents, people who themselves suffer from salmonellosis, and can become infected from geese. Adults are almost lifelong bacteria carriers. The microbe is extremely resistant, and remains viable in frozen goose carcasses for years. register various forms the course of diseases in geese - from fulminant to chronic. The following symptoms are observed:

• oppression;
• drowsiness;
• loss of appetite;
• thirst;
• conjunctivitis;
• swelling of the joints;
• paralysis;
• geese develop cloacitis, yolk peritonitis.

It is possible to cure the disease with nitrofurans, or antibiotics, sulfonamides. The use of Tromexin is shown. Preventive methods of control include immunization of geese.

colibacillosis

The causative agent is a bacterium that constantly lives in the intestines. The disease occurs as a result of a weakening of the body due to a violation of zoohygienic parameters. Grown up 2-3-month-old goslings get sick. They are depressed, sleep constantly, move with difficulty, try to drink all the time. Therefore, the treatment consists in replacing water with an antibiotic solution, mainly a preparation containing Enrofloxacin - Baytril, Enromag, etc. An exacerbation of the disease occurs in geese during the laying period. Fix peritonitis, prolapse of the oviduct, salpingitis.

• lethargy, inactivity;
• anemia;
• goslings are cold;
• mucous diarrhea occurs, often with blood;
• the litter becomes sticky.

Aspergillosis

The disease is caused by a pathogenic fungus. Goslings suffer mainly in case of violation of the content parameters. Microbes actively multiply in the litter that has not been changed for a long time and infect the bird. Observed mainly damage to the respiratory organs of geese. All types of birds are affected. Geese and their chicks with clinical symptoms are destroyed, conditionally healthy are treated with antimycotics or aerosolized with iodine monochloride. The room is sealed, the drug is poured into a ceramic or glassware with aluminum powder or chopped wire and leave for 30-40 minutes. As a result of the reaction, gas is released purple. Microbes do not have a mechanism for getting used to iodine, so they die. The disadvantage of this method is the high corrosivity of the halogen.

Infectious cloacitis

Another name is neisseria. They are called diplococci. The disease is aggravated by the addition of secondary microflora. It occurs in adult geese during the mating season. It is characterized by the following features:

• hyperemia of the cloacal mucosa;
• erosions, fibrinous scabs occur;
• eggs are not fertilized;
• in ganders, the penis is bent and falls out;
• a sick bird loses weight, mortality can reach 12%.

Pathology should be distinguished from non-infectious cloacitis that occurs for other reasons. Goose disease can be treated according to the following scheme:

1. Bicillin-5 is pierced intramuscularly, once.
2. Five days in a row with concentrates give Levomycetin or Tetracycline with double feeding.

If the need arises, after a weekly interval, antibiotic therapy is repeated by changing the drug. With a preventive purpose, during the period of completing the reproductive herd, geese are examined. Sick and suspicious are rejected, the rest are given a course of antibiotic therapy. Disinfection of walks, inventory, premises.

Worms

Repeated deworming of goslings is carried out at four weeks, the next - six months later. In individuals of the reproductive herd, worms are expelled twice - in spring and autumn. Use Levamisose, Albendazole or Tetramisole with morning feed distribution. So that helminths do not develop immunity, drugs are recommended to be changed annually.

To prevent the spread of infections, it is necessary to practice separate keeping of geese of different ages.

Non-communicable diseases

The following non-infectious diseases of geese are distinguished:

• avitaminosis D;
• diarrhea;
• cannibalism;
• blockage of the esophagus;
• non-contagious enteritis;
• non-infectious cloacitis.

Avitaminosis D

Pathology develops as a result of vitamin deficiency and lack of ultraviolet radiation. The disease of goslings is called rickets. It is characterized by a violation of the growth of bones, their curvature, growth retardation. Avitaminosis D is a disease not only for goslings, but also for laying hens. In this case, the lack of calciferols is combined with an increase in the need for calcium in laying hens. The disease is manifested by softening of the beak, bones, thinning of the shell and the appearance of eggs without it.

If the poultry farmer uses compound feed, BVMK or premixes, his geese do not have beriberi and other problems. Partially correct the situation can be introduced into food vitamin preparations, first of all, fat-soluble - Trivitamin, Tetravit, etc.

For the treatment of avitaminosis D in geese, in addition to vitamins, it is required to add a source of Calcium. Its most acceptable sources are Shell or Tricalcium Phosphate.

Diarrhea

It is important to find out what causes diarrhea in goslings - infection or inadequate hygiene conditions, as well as feeding errors. In both cases, treatment must begin with the correction of zoohygienic parameters. The main enemy of the caterpillar's body is dehydration, so you need to take urgent measures and call a veterinarian.

From folk recipes You can seriously consider adding wheat bran to the feed of geese, as they absorb moisture well and thicken the droppings. This is if the goslings have retained their appetite. The recipe, with drinking a weak solution of potassium permanganate, is not bad, but there are problems with acquiring the drug. Therefore, it is better to use Furacilin, Baytril, Tromexin or another antimicrobial agent.

Cannibalism

The bird begins to peck at each other due to excessive illumination, crowding, as well as a lack of vitamins, trace elements, and protein. Geese, with traces of pecking, are removed, violations are corrected.

Blockage of the esophagus

Observe with a lack of drinking when feeding dry mixes. Goslings have shortness of breath, the beak is constantly open, the gait is unsteady. Treat folk remedy- pour vegetable oil 40–60 ml and try to squeeze the contents out of the beak.

Non-infectious cloacitis

It must be distinguished from neisseriasis. The cause of non-contagious cloacitis in geese is fights or gross violations of feeding - an imbalance of minerals and vitamins. Symptoms resemble the course of an infectious cloacitis. With the development of pathology in laying hens, the oviduct may fall out or yolk peritonitis may occur. Treatment consists in washing the goose's cloaca with antiseptics. The oviduct is adjusted, errors in feeding are eliminated.

Conclusion

A responsible poultry farmer who decides to start breeding geese must understand that this technological process, which is a list of techniques that are performed in a certain sequence. The success of the enterprise depends on the scrupulous execution of all points, the adoption of balanced, timely decisions in the event of unexpected situations.

Diseases of goslings cause great damage to the economy, and their treatment should be carried out in a timely manner. Otherwise, the young will lag behind in development and growth, or there is a risk of losing livestock altogether. To prevent such consequences, it is necessary to carry out and properly care for goslings.

Causes of diseases

Diseases of goslings and their treatment

Consider some diseases and methods of dealing with them.

Viral enteritis is a disease that is characterized by damage to the intestines, the heart system, and the liver. This disease leads to the death of goslings up to 95% of the total population. They become infected through food, water, air, and the virus is also transmitted from one bird to another.

Disease symptoms and preventive measures

The depressed look of goslings, half-closed eyes, trembling, yawning, lack of appetite indicate malaise. Sick birds cluster and mostly sleep, they develop and experience stunted growth.

To prevent this disease, goslings must be vaccinated both adults (one and a half months before the start of laying eggs) and young animals (up to 28 days old). After a couple of weeks, you need to repeat the procedure.

Cholera or pasteurellosis is distinguished by a high mortality of birds, when, with a particularly acute course of the disease, seemingly healthy goslings suddenly die. The sources of infection are the same as in the above case.

Symptoms of this disease goslings and their treatment

Sluggish state of the bird, secretion of mucus or foam from the nasal openings and beak, temperature up to 43 degrees, diarrhea of ​​​​gray, yellow or green, thirst and lack of appetite. All this entails the death of the bird. This disease can also take a chronic form, then adult geese begin to limp, and their wings sag.

In order to prevent the development of the disease, it is necessary to vaccinate, and if the goslings are still sick, then you will have to kill those who have symptoms, and the rest are prescribed antibiotics and biomycin for prevention.

Ticks (Persian, chicken);

Bed bugs (mostly bed bugs);

These are far from all the diseases that geese are susceptible to. Many of them lead to 100% death of birds, but it is important to prevent them. Only then will it be possible to save the livestock or completely avoid the disease of goslings, and their treatment will be more effective if the above conditions of keeping and feeding regimen are observed.

Acute disease of goslings early age, characterized by damage to the intestines, heart, liver and accompanied by high mortality of young animals (30-95%) in the first three weeks after hatching, but 6-12-day-old young animals are more likely to get sick. The disease is very contagious and is transmitted from sick and recovered birds through hatching eggs. Infection occurs through the air or with food and water.

The disease is caused by a virus that is localized in the internal organs. The main source of the disease is sick birds that excrete the virus with droppings. An ill bird for a long time (3-4 years) remains a virus carrier.

The main symptoms of the disease are as follows: goslings are depressed, gather in groups, tremble, strive for warmth, stand more with half-closed eyes, sometimes fall asleep completely, lowering their head or tilting it to one side, often yawn, do not respond to sound, no appetite. Some birds have conjunctivitis, nasal discharge. In the future, watery diarrhea appears with an admixture of blood. Sick and recovered goslings lag behind in growth and development.

When a dead bird is opened, a slightly enlarged heart is noted, the myocardium is pale, flabby, the color of boiled meat. The liver is enlarged, filled with blood, the gallbladder is filled with bile. The spleen is light pink, sometimes dark red. The glandular stomach usually contains mucus. The intestines are inflamed. Goslings younger age catarrhal and hemorrhagic inflammation of the intestinal mucosa is more often found, and in the older ones - fibrinous inflammation.

For the purpose of prevention, young and adult geese are vaccinated with a live vaccine. Replacement young animals are vaccinated once at 21 - 28 days of age, adult geese - 1.5 months before the start of laying, again after two weeks.

Vaccination of geese against viral enteritis in a goose farm is mandatory.

Pasteurellosis (cholera)

An infectious contagious disease that occurs superacutely, acutely or chronically with septicemia and high mortality. Domestic and wild birds of all kinds are affected, geese and ducks are especially susceptible.

The source of infection is a sick and recovered bird, and the transmission factors are contaminated water, food, care items, and the surrounding air.

The incubation period lasts from several hours to 2-5 days. The superacute course is characterized by the sudden death of an outwardly healthy bird. At the same time, the number of dead birds is growing rapidly.

In the acute course of the disease, the bird becomes lethargic, foamy mucus stretches from the nasal openings and beak. Body temperature increased to 43.5 degrees. The stools are liquid, gray, yellow or greenish in color, sometimes with an admixture of blood. There is no appetite, strong thirst, general weakness appear, and the bird dies.

The chronic course of pasteurellosis is observed after an acute manifestation of the disease. From the nasal openings of a sick bird, viscous outflows appear, difficulty breathing is observed. In adult geese, arthritis and inflammation of the tendon sheaths are noted, resulting in lameness and drooping of one or both wings. The illness lasts from several weeks to several months. A bird that has been ill with pasteurellosis acquires immunity, but is an open carrier of the infection.

With hyperacute course of pasteurellosis, there are no changes in the corpses of birds. As a rule, well-fed geese die. Sometimes exudate is found in the heart shirt, and petechial hemorrhages under the epicardium.

In the acute course of the disease in a dead bird, hemorrhages are found on the epicardium, serous membranes of the digestive organs, peritoneum, pleura and subcutaneous tissue. The pericardium and epicardium are covered with numerous hemorrhages and, as it were, spattered with blood. An accumulation of fibrous exudate is found in the abdominal cavity.

In the chronic course of the disease, the corpses are emaciated, the liver is enlarged, cherry-colored, necrotic foci are found in its parenchyma. Sometimes there is pulmonary edema.

When the disease is established, all sick birds from a dysfunctional poultry house are immediately killed. The poultry house, paddocks, the territory adjacent to the poultry house are thoroughly cleaned and disinfected. At the same time, the geese of other poultry houses are provided with full-fledged feeding and their conditions are improved. For the remaining livestock, for prophylactic purposes, the following antibiotics and sulfonamides are prescribed: biomycin once subcutaneously at a dose of 25,000 - 50,000 per 1 kg of live weight; Levomycetin at a dose of 30 mg/kg of live weight mixed with 1 g fish oil 2 times a day for 5 days in a row; sulfadimezin at a dose of 0.2 g per head 2 times a day with food for 5-6 days; sulfadimezin in the form of a 1% solution instead of drinking water; spofadizin with feed 2 times a day at a dose of 0.075 g per 1 kg of live weight of poultry for 3-4 days.

You can vaccinate against pasteurellosis of geese no earlier than 5 days after application. medicines. For vaccination, a live or inactivated vaccine is used.

Salmonellosis (paratyphoid)

Acute disease. Goslings are most susceptible from 5 days to a month of age. But a chronic course is also observed in adult geese. An ill bird for a long time (up to 2.5 years) can remain a bacteriocarrier and carries infected eggs, from which infected goslings hatch. The susceptibility of goslings to this disease increases with poor feeding and maintenance, underheating or overheating. A sick bird with droppings releases the causative agent of the disease - salmonella. They are very resistant to adverse environmental factors, retain the ability to infect birds, being in the litter up to 1 year 8 months, in the soil up to 120 days, on the surface of the premises up to 150 days. In frozen carcasses, salmonella persist for up to 2-3 years, which poses a certain danger to humans.

Salmonellosis occurs fulminantly, acutely, subacutely and chronically. With a fulminant course, no clinical signs of the disease are observed, death occurs suddenly.

In the acute course of the disease, weakness, drowsiness, thirst, decreased appetite, shortness of breath are noted. Nervous phenomena are characteristic: convulsions, paralysis. There is lacrimation, turning into purulent conjunctivitis.

In the subacute course of the disease, goslings experience difficulty breathing and diarrhea. The surviving goslings are exhausted and develop poorly.

Chronic disease often occurs in grown-up young animals. In this case, diarrhea, exhaustion, swelling in the joints, lameness, nervous phenomena, conjunctivitis are observed. In an adult bird, the disease proceeds without visible signs. During the laying period, diseased geese have inflammation of the cloaca, oviduct, and ovaries. Sometimes their joints swell, wings drop, and diarrhea appears.

When a dead bird is opened, an accumulation of exudate is found in the pericardial sac, the heart is flabby, the lungs are hyperemic, the liver is enlarged by 1.5-2 times, filled with blood, fibrous overlays are visible on its surface. In the parenchyma of the liver, multiple necrotic nodules of a grayish-yellowish color are found. gallbladder enlarged, filled with bile. Catarrhal inflammation of the intestine is noted, in some cases peritonitis (inflammation of the peritoneum) is observed.

When a diagnosis of salmonellosis is made, sick and suspected birds are removed from the herd and killed. Inventory, premises and adjacent territory are disinfected with a 3% solution of sodium hydroxide, a 2% solution of formaldehyde or a 2% solution of freshly slaked lime. Drinking bowls and feeders are thoroughly washed in hot water and disinfected with a 5% bleach solution.

The most effective therapeutic agents are nitrofuran preparations (furazolidone up to 5 mg per caterpillar with food 1 time per day for 8-10 days in a row), antibiotics (biomycin, tetracycline, oxytetracycline 20 mg per 1 kg of live weight with food 2 times a day in for 5-10 days), sulfamides (sulfadimezin 200 mg per 1 kg of live weight with food 2 times a day for 3-5 days).

Conditionally infected young geese are immunized orally with a live avirulent vaccine against salmonellosis of waterfowl at the age of 2-4 days, if the population of the parent flock was not vaccinated before the start of laying. Against the background of maternal immunity, goslings are vaccinated at the age of 8-10 days. An adult bird is vaccinated 20-30 days before the start of the productive period twice with an interval of 4-5 days. summer cottage medicines stop 28-45 hours before vaccination.

Salmonellosis is a zoonotic disease, meaning it can be transmitted from humans to birds and vice versa.

Aspergillosis

Acute, subacute and chronic disease of geese, characterized by damage to the respiratory organs. Young animals have a high mortality, adult birds are more stable.

The causative agent of the disease is a microscopic fungus from the genus Aspergillus. Infection occurs through aerogenous internal organs(heart, liver) Aspergillus penetrate with blood flow.

The source of the pathogen is a sick bird, as well as infected feed, litter, soil. The spread of aspergillosis is possible through incubators, where spores of the fungus enter with hatching eggs from dysfunctional poultry houses. Fungi cause the death of embryos, appears a large number of"cuffs" that rupture and infect environment. Goslings become infected during hatching in the first days of life, as a result of inhalation of air containing spores of the fungus. Dampness in the room, wet bedding, microclimate disturbance, bird crowding predispose to the onset of the disease. The disease most often occurs in the spring.

A distinctive feature of Aspergillus is unpretentiousness to living conditions and high resistance to chemical and physical factors.

A sick bird becomes lethargic, drowsy, inactive. In the acute course of the disease, the respiratory organs are mainly affected. During inhalation, a sick bird stretches its neck, opens its beak, swallows air, and often sneezes. A serous, sometimes foamy fluid flows from the beak and nasal openings. With the defeat of the air sacs, exhalation is accompanied by a wheezing. There is a disorder of the gastrointestinal tract, progressive exhaustion. Before death, the bird has convulsions. Among goslings, the case can be 50-100%.

At autopsy in a dead bird, a lesion is noted in the larynx, at the site of the bifurcation of the trachea, in separate air sacs. In the lungs, nodules of various sizes are found (from small millet-shaped to large). With a prolonged process, Aspergillus nodules form in the trachea, bronchi, lungs, as well as the liver, spleen, and kidneys. Nodules of dense consistency, gray-white or yellowish-gray. A white coating forms on the mucous membranes and serous membranes.

The most effective destruction of the fungus in the external environment and in the poultry house is burning with fire. blowtorch(flamethrower) walls of the room, metal objects, inventory. The use of formaldehyde in the form of an aerosol is also effective. It has been established that vitamin A concentrate increases the resistance of young birds to aspergillosis.

In case of an outbreak of the disease, it is recommended to use an iodine aerosol at the rate of 20 ml of a 0.5% solution per 1 cubic meter premises for 5-6 days with an exposure of 40 minutes. FROM drinking water it is recommended to give a 0.05% solution blue vitriol 3-5 days in a row. For the purpose of prevention, goslings can be treated with iodalluminum aerosol. Nystatin is also used at a dose of 25-30 mg per 1 kg of poultry live weight with feed 2 times a day for 7-10 days.

The main condition for the effective action of drugs is the exclusion of moldy feed and moldy bedding. With aspergillosis, it is forbidden to use antibiotics, as they contribute to the development of the fungus.

colibacillosis

An infectious disease of young animals of an early age, an adult bird is less likely to get sick.

The main source of infection is sick geese that excrete the pathogen with droppings, as well as infected objects, equipment, feed, water, etc. A sick bird remains a carrier of infection for a long time, the disease is transmitted through eggs.

The disease is promoted by violations of the veterinary and sanitary regime, technology of keeping and feeding.

In young animals, colibacillosis is acute and is manifested by oppression, thirst, and drowsiness. Possible conjunctivitis, nervous phenomena, diarrhea, sometimes with an admixture of blood. Two-three-month-old goslings weaken, hardly rise and move slowly. In an adult sick bird, prolapse of the oviduct, inflammation of the ovaries, and peritonitis are observed. The disease is especially pronounced during oviposition. The death of geese in this case reaches 20%.

At autopsy, young animals find an increase and blood filling of the liver and spleen. Vessels of the mesentery and kidneys are hyperemic. In the pericardial sac there is an accumulation of straw-colored serous exudate. The small intestine is inflamed. In an adult bird, the liver is light brown, dense, brittle, the ovary is hemorrhagically inflamed, the mucous membrane of the ovary is catarrhal, in males there are pinpoint hemorrhages in the testicles. Sometimes single and multiple tumor-like formations ranging in size from a pea to chicken egg in the caecum, liver, less often in the gastrointestinal tract, pancreas, spleen, kidneys, ovaries, oviduct, lungs, air sacs.

A sick bird is killed and destroyed. Clinically healthy livestock are treated. Antibiotics are prescribed with the determination of the sensitivity of isolated microbial cultures. It should be noted that pathogenic colibacilli quickly acquire resistance to antibiotics, so the regimen and method for the prevention and treatment of colibacillosis should be periodically changed. The best means- neomycin 50 g 1 time per day with feed for 6-10 days, biomycin and tetracycline 20 mg each, chloramphenicol 30 mg per 1 kg of bird live weight. An excellent tool for the treatment and prevention of colibacillosis is baytril, which is drunk with water for birds.

Passive immunity is transmitted to young animals through eggs and lasts for 1-3 weeks, active immunity lasts up to three months and is developed during vaccination. The vaccine is given to young animals at 3 and 6 days of age.

As a prophylactic for goslings, in the first 3 days, propionic acidophilic broth culture is drunk instead of water in the ratio of 1 ml of the drug per 10 ml of water.

Incubators are treated with formaldehyde vapors, and day-old goslings are treated with antibiotic aerosols.

Compliance helps prevent disease sanitary requirements, feeding and keeping regimes, as well as feeding vitamin supplements to poultry.

Influenza

Acute infectious disease of young geese. The causative agent is a short stick. The microbe is unstable in the external environment. When exposed to a temperature of +50 degrees, he dies within 10 minutes, and +60 degrees kill him after 30 seconds. Low temperatures, on the contrary, as if preserve the pathogen. So, at a temperature of -17 degrees, it lasts up to two months. Indoors - on walls, bedding, sand, grain fodder - at room temperature, the pathogen remains viable for no more than three days, and in water - up to 50 days.

Disinfectants kill the pathogen fairly quickly. So, when exposed to a 1% solution of sodium hydroxide, 1% emulsion of creolin, 0.5% solutions of bleach, carbolic acid, it loses its viability after 3 minutes.

Young geese are susceptible to the disease. Infection occurs through scratches and injuries of the skin, as well as through the consumption of food and water contaminated with microbes. Infection is also possible through the respiratory organs. The main source of infection is a sick bird, which releases the pathogen into the environment. Sick young animals develop weakness, body temperature rises to + 43-44 degrees, appetite is lost. The wings of the geese hang down, the young sit with an open beak, breathe often, sometimes wheezing is heard. Swelling of the head and legs is often noted. After 2-5 days, coordination of movements is disturbed, diarrhea appears. Mortality among sick goslings reaches 70%.

When a disease appears, obviously sick goslings are killed, the carcasses are scalded with boiling water. Conditionally healthy young animals are transferred to a clean room, and the former ones are disinfected. For prophylactic purposes, a 0.5% solution is drunk instead of water. of hydrochloric acid or formalin diluted in water in a ratio of 1:10000.

Neisseria goose

An infectious disease characterized by reddening of the mucous membrane of the goose cloaca, the formation of fibrinous scabs, bleeding erosions, and swelling of the affected tissues. In ganders, the disease is manifested by sclerotic inflammation of the penis, curvature and prolapse of the organ from the cloaca. The causative agent is a diplococcus from the genus Neisseria. The accompanying microflora can be staphylococci, streptococci, proteus and other bacteria. Geese over the age of 16 months are susceptible to the disease. Ganders are particularly susceptible to infection.

The disease proceeds in the form of an epizootic, as well as sporadic cases, and is characterized by a sharp increase in the number of unfertilized eggs (up to 90%), since ganders lose their ability to mate. Cases of death of adult geese from the disease were noted (2.5 -12%).

The source of the pathogen are sick and recovered geese. Infection occurs sexually, transmission of infection through infected bedding is possible. The incubation period of the disease is 3-15 days. The disease is noted in the breeding period, when the mating of geese occurs. The duration of the disease is 1-1.5 months. The bird loses weight and dies during the phenomena of the septic process.

At a pathological autopsy of a dead bird, changes in the cloaca and penis (fibrinous scabs, erosions, ulcers, scars, sclerotic changes) and peritonitis are noted. The diagnosis of neisseriasis is established on the basis of a complex of epizootological, clinical, pathoanatomical data and laboratory studies (detection of diplococcus in pathological material, isolation of the pathogen culture and bioassay). Neisseriasis of geese should be differentiated from diseases of the cloaca and penis, in which the causes may be injuries, competitive fights of ganders, poor living conditions, beriberi.

Bicillin-3 (once, at a dose of 60 thousand units / kg of live weight) or bicillin-5 is administered intramuscularly to a bird from a dysfunctional herd for therapeutic and prophylactic purposes. Simultaneously with the feed give chloramphenicol 0.15 g per head twice a day for five days. Instead of levomycetin, tetracycline or monomycin can be given with food. If necessary, this course of treatment is repeated after 6-8 days.

In the breeding season, once every 1-1.5 months, a clinical examination of the genital organs of geese is carried out and sick and suspected individuals are culled. The rest of the birds are given antibiotics. This procedure is repeated during the period of the autumn acquisition of the parent flock of geese. Industrial premises, walking, containers and inventory are disinfected in accordance with the instructions.
