Breeding and keeping chickens is quite an interesting and profitable business. But, like any other creature, they are subject to various kinds of diseases and diseases. this is a major problem in the poultry industry. Of course, it is best to prevent diseases in your livestock by regularly carrying out prophylaxis, but if this does happen, then you need to take all the necessary measures - correctly determine the diagnosis and make immediate treatment.

Unfortunately (but not so often), there are very dangerous forms of infectious diseases, because of which you have to put the whole herd of chickens under the knife.

Any poultry farmer should have an understanding of the diseases that his chickens may be susceptible to, have a full or at least partial understanding of the symptoms and methods of treatment.

We will talk about what chicken diseases are, what they lead to, as well as about the symptom and treatment in the presented article.

For the prevention of diseases of chickens, birds, it is necessary to constantly examine and observe their behavior.

The good health of chickens is indicated by constant activity, excellent appetite, the bird constantly drinks water, but within the normal range. The plumage should be in good condition: shiny and smooth, feathers not ruffled. Healthy chickens stand steadily on their feet, and there are also no collapses on one of the sides.

When examining domestic chickens, to identify the disease, first of all, attention should be paid to:

• skin, as well as feathers and down
• respiratory system
• body mobility (head mobility, wings and legs mobility)
• digestive organs
• leg condition

If any pathology is detected, the first thing to do is to isolate the sick chicken from the general herd. In this way, you will avoid infection of the entire livestock, in the event that it turns out that the disease is infectious. After that, it is necessary to make the correct diagnosis and prescribe treatment. The best thing, of course, would be to show the bird to the veterinarian. However, if this is not possible, then you need to act independently.

Diseases of chickens are divided into contagious and non-contagious. Of course, the most dangerous are contagious, as they can lead to mass death of livestock. In this regard, non-communicable diseases are less dangerous, but they cannot be ignored. Contagious and non-contagious diseases, in turn, are divided into several more categories, which are listed below.

Below is an almost complete list of chicken diseases, divided into certain types of diseases. After describing each disease, the main symptoms, treatment and prevention of the disease will be attached. Armed with this knowledge, you yourself will know how to treat chickens for a particular disease, without contacting a veterinarian.

Healthy chickens - consumer safety. The health of pets is the key to a successful farm. Successful farming: the health of domestic chickens.

The most common poultry is the chicken. Caring for her is not difficult, however, it is important to pay special attention to the health of the bird.

Experts recommend periodically organizing preventive action. After all, saving sick chickens is quite difficult and costly. What can cause chickens to get sick? What are the main signs of disease? How to treat poultry? Which is worse for chickens: coccidiosis syndromes or bird flu? We have tried to answer all these questions in the material below.

What can kill your chickens?

Ways to prevent infectious diseases in domestic chickens

The main method of prevention is a balanced diet and good care. Please note that there is a risk of death of young animals that are in the same room with adult chickens. What to do if your bird is sick:

• It is best to place them in different enclosures.
• To protect against infectious diseases, be sure to include treatment with disinfectants at least once a month in preventive actions.
• If the bird is sick, first of all it must be placed separately, and this procedure should be carried out immediately. Otherwise, damage to the internal organs of the bird will occur, in the worst case, a fatal outcome.
• Moreover, if the symptoms are complex and the treatment no longer makes sense, this individual will have to be disposed of by destroying it.

The most common poultry diseases

Coccidiosis in chickens symptoms that can be detected at home

Distinctive features of the symptoms of coccidiosis: diarrhea, in the early stages of the disease, the feces are greenish in color with mucus, in a neglected state - dark brown with blood, the young chicken does not move well and is lame at the same time. According to external data - the bird has pale earrings, scallop and mucous membranes, ruffled feathers. The recovery of chickens is slow. It takes place in two courses, lasting an average of three days, followed by a break of two days.

How to treat coccidiosis in poultry

The preparations are dissolved in water or mixed with food. Among the drugs that save the livestock are: norsulfazol, bichonolate, furagin, coccidine, sulfadimezin, sulfadimethotoxin, furazolidone, decox, statyl, sacox, ardinone-25, and also baycox.

Disease prevention

But for prevention, you don’t need so much time and effort. The main thing is cleanliness in the chicken coop and in the cages. You just need to disinfect the chicken coop and equipment, it is best to do this with a solution of soda or bleach and ammonia.

Other dangerous poultry diseases

Regardless of their age, chickens are susceptible to colibacillosis caused by E. coli. In a complex form, the disease occurs in chickens, while in an adult it is chronic. This virus is dangerous even for humans, so treatment of the bird should be started immediately. In the treatment, mainly medicines for chickens are used, such as biomycin and terramycin.

Smallpox in domestic chickens

There are diseases in which the best way out of the situation is to get rid of the bird. Among those - chickenpox. It is impossible to look at photos and pictures with a sick individual without disgust. Due to illness, yellow so-called pockmarks appear on the crest and earrings. In addition, the laying hen's eyes and liver are affected. Treatment, as in other cases, can become effective if it is carried out urgently. In a neglected form, the bird cannot be cured and will have to be destroyed, otherwise it can lead to an epidemic in the chicken coop. Smallpox is a viral disease that spreads slowly. This disease has two types:

• skin form,
• diphtheria form.

The first type of the disease is characterized by the development of nodular, proliferative skin lesions on parts of the bird's body without plumage. Mortality in the cutaneous form is very low. The second form of the disease affects the mucous membrane of the upper respiratory tract of birds. The probability of mortality among the livestock is very high. Avian pox viruses infect birds of both sexes (including laying hens), of all ages and breeds. The disease is distributed throughout the world.

Smallpox is usually treated with a special vaccine. It is developed from a "chicken embryo" and consists of live, unattenuated laying pox virus. If used incompetently, the virus can cause serious illness in chickens. The vaccine is administered into the wing web of four-week-old chicks and laying hens approximately 1-2 months before the expected onset of egg production. Chickens can be vaccinated one day after birth. One vaccination provides protection for life.

Bird flu

One of the most merciless is the disease that every person hears - bird flu. Everyone is afraid of him - from a weak bird and even to a strong person. Indeed, today it has more than 15 varieties.

How does it affect chickens? Can they be protected?

Let's consider everything in order. Bird flu symptoms in chickens and roosters can be seen literally from the first days of the disease. First of all, we note that the virus affects the nervous system of birds, in chickens there is a discoordination of movements, they can fall, stagger, their necks and wings are bent, in addition, there is an increase in temperature to 44 ° C, thirst sets in. Look also for signs of bird flu, such as:

• blackening of the comb and earrings,
• hoarse breath,
• diarrhea,
• convulsions,
• neurosis.

Perhaps internal hemorrhages, impaired blood circulation in case of damage to the vascular system, which leads to the H5N1 influenza subtype. In a mild form, the condition of the feather worsens in chickens and a decrease in egg laying is observed. In this case, the disease goes away even without much human intervention. In the acute form, which is caused by type H5 and H7, a number of external manifestations are observed, treatment is useless.

Is there a cure for bird flu?

No matter how scary it sounds, no preventive methods have yet been found for chickens, and today this virus in domestic chickens is incurable. In order to protect chickens from this terrible scourge, it is recommended isolation of poultry from contact with wild representatives.

Sick birds, as well as those that came into contact with her, are killed to prevent further spread of the virus. In no case should you eat meat from a sick bird. Therefore, take care of your laying hens so that grief bypasses you.

Newcastle disease, pasteurellosis, pullorosis, salmonella

Unfortunately, Newcastle disease is also incurable; it also affects the entire body of the bird. The disease proceeds very quickly, as a result, the bird dies. Experts advise to burn the corpses or bury them, but be sure to cover them with fresh lime. Another disease to watch out for is pasteurellosis. It is provoked mainly by rodents and chickens that have had this disease. Treatment is through vaccinations. It is characteristic that the infection lives for a long time in litter, water and feed. The corpses of individuals suffering from pasteurellosis are burned.

What can cause disease in domestic chickens?

Summing up

We examined the main types of diseases, there are a lot of their varieties. As you can see, it's important to be vigilant about the cleanliness of the chicken coop, cages, to surrounding animals and to the behavior of the birds themselves - this is the only way you can save chickens and they will delight you with their rapid growth.

What deviations in normal behavior and external state indicate the disease? Many diseases are characterized by a rapid course, which leads to the loss of livestock, in order to avoid this, it is necessary to inspect the herd daily for alarming symptoms. So, diseases of laying hens and their treatment, photos and descriptions of ailments - this is worth talking about in order to know what actions to take in a particular situation.

What should you pay attention to?

Diseases of laying hens at home can be cured if the symptoms are identified in time. First of all, the following general symptoms appear:

• the bird becomes lethargic;
• spends most of the time on the perch;
• does not want to move and sits with his eyes closed;
• apathetic state is replaced by excitement and anxiety;
• difficulty breathing, the bird may make sounds atypical for it.

If the following symptoms are found, treatment should be started immediately:

• the appearance of mucous secretions;
• the presence of inflammatory processes near the visual organs or the respiratory system;
• the condition of the feather cover worsens, feathers may fall out, look sloppy and dirty;
• digestive system disorder - birds begin to have diarrhea.

Characteristics of diseases

Everything is not so simple here, and not every disease can be treated. With some infections, you can lose all the livestock. It is because of this that such ailments must be taken with all seriousness.

Pulloroz

The disease has another name - typhus. Both adult birds and young birds are susceptible, the first sign is a digestive upset. It is transmitted by airborne droplets from sick individuals to healthy ones. Sick laying hens transmit the virus to their eggs, and as a result, infected young stock are born. The disease is characterized by an acute course (at first), then a chronic form begins, which chickens get sick throughout their lives.

Symptoms:

• chickens become lethargic and move little;
• refuse food, diarrhea begins, the bird is very thirsty;
• the color of the feces becomes yellowish, frothy;
• rapid breathing;
• the young are weak, the chickens fall on their backs or sit on their paws;
• in adult livestock, there are changes in the color of the crest, they become pale in earrings;
• there is complete exhaustion of the body.

Treatment Methods

An accurate diagnosis can only be made with the help of a biological preparation containing a pullorose antigen. If the disease is detected, treatment should be started immediately.

As soon as the first signs appear, sick birds must be transferred to a separate room and given an antibiotic. Most often, treatment is carried out with biomycin or neomycin. These medications are sold exclusively in veterinary pharmacies, where you can also consult about the use. It would be useful to use furazolidone for both sick and healthy individuals, it is added to the feed.

Preventive measures

A daily inspection of the livestock is necessary in order to timely cull sick young or adult birds. In the poultry house, sanitary and hygienic conditions must be observed. Regularly ventilate the house.

It's important to know! Typhus is transmitted to humans.

Pasteurellosis

Avian cholera (second name) affects both domestic and wild birds. It has two forms: acute and chronic. Spread by a microorganism - Pasteurella, which is very well adapted to environmental conditions. Pasteurella retains the ability to survive in excrement, aquatic environment, feed, corpses. Carriers can be birds that have recently had a disease or are currently ill. Also, avian cholera spreads among rodents.

Symptoms:

• depression of the state, inactivity;
• birds have a fever;
• refusal to feed and with it a strong thirst;
• a malfunction of the digestive system is characterized by diarrhea;
• liquid feces can be green and bloody;
• mucous discharge from the nasal cavity;
• breathing problems, wheezing is heard;
• the joints of the extremities swell, bend.

Treatment Methods

Treatment is carried out with sulfa drugs. Sulfamethazine is mixed with water or feed at the rate of 0.1% of the total volume of water, and 0.5% of the feed. Both healthy and sick birds should be given green grass and vitamin complexes in large quantities. To carry out the disinfection of the premises for birds and all inventory.

Preventive measures

The owner must take measures to exterminate rodents, close all available ways of their penetration to bird food. Before laying eggs in the incubator, they must be disinfected.

A sick bird must be destroyed. To maintain a healthy livestock, timely vaccination against cholera is done.

It's important to know! The disease is transmitted to people, usually in an acute form.

salmonellosis

In another way, the disease is called paratyphoid. There are two types of flow: acute and chronic. Chickens are most commonly affected. The causative agent of the disease is salmonella. Method of transmission: from diseased individuals to healthy ones, incubation material may also be affected. Salmonella can easily penetrate the shell, and they can also be in feed, litter, or transmitted by air. As soon as symptoms are detected, diseased animals should be isolated and treated. Paratyphoid is contagious and extremely dangerous.

Symptoms

• birds become lethargic and weak;
• having difficulty breathing;
• there are tumors on the eyelids, the eyes are watery;
• indigestion in the form of foamy diarrhea;
• the joints of the limbs swell, with paratyphoid the bird tips over on its back, convulsive movements begin with its paws;
• the area near the cloaca is inflamed, as well as the onset of inflammatory processes in the internal organs.

Treatment Methods

Paratyphoid is treated with furazolidone, it is necessary to conduct a course for 20 days. The tablet is dissolved in 3 liters of water and poured into a drinking bowl. A course of streptomycin 100 thousand units per kg of feed is prescribed together, twice a day. Treatment should not last less than 10 days. Then stop giving the medicine for one week, and repeat the course.

Preventive measures

To maintain health, immune serum is used for vaccination. As soon as the treatment is completed, disinfection measures are carried out in the premises for birds, and all inventory is also processed.

Ill birds become carriers of paratyphoid and can pass it on to healthy livestock, it is best to destroy such birds. If salmonellosis is detected in at least one chicken, synthomycin is drunk for everyone else at the rate of 15 ml per head or chloramphenicol is used. The dose is divided into several portions. Dacha occurs three times a day - 7 days.

It's important to know! The disease is transmitted to people and has an acute form.

It is a very common disease. Neurolyphotosis or infectious paralysis (Marek's name) is caused by a virus that affects the central nervous system, the organs of vision. Tumors are formed on the skin, bones of the skeleton, internal organs. When infected with Marek, the work of the musculoskeletal system is disrupted.

Symptoms:

• refusal to feed, signs of general exhaustion;
• the iris of the eye changes color;
• there is a narrowing of the pupil, often leading to blindness;
• pallor of the comb, earrings, mucous membranes is observed;
• disruption of the musculoskeletal system;
• paralyzes goiter;
• the bird is practically unable to move, obvious lameness is visible.

Treatment Methods

To establish a diagnosis, you need to contact a veterinarian. There is no cure and the livestock must be destroyed. Viru is dangerous because it has survivability and can exist in feather follicles for a long time.

Preventive measures

It is necessary to vaccinate daily young, this is the only thing that will help prevent infection. It is pointless to vaccinate an adult livestock, there will be no positive result. Before buying young animals, you must familiarize yourself with the veterinary certificate of vaccination.

It's important to know! It does not pose a threat to people, not a single case has been identified.

Bronchitis of an infectious nature

First of all, the respiratory system in young animals is affected, and in the adult livestock, the reproductive organs are affected. Egg production is on the decline and in some cases stops forever.

The virion virus is the causative agent. It can continue to live in chicken eggs and internal tissues. The virion is easy to deal with with ultraviolet irradiation and a number of disinfectants. The method of transmission is airborne, as well as with the help of bedding and tools for work. As soon as infectious bronchitis is detected, quarantine measures on the farm will have to be introduced for a year. The disease is extremely dangerous for nearby poultry farms. Herd mortality - 70%.

Symptoms:

• chickens begin to cough, breathe with difficulty;
• mucous discharge from the nasal cavity, rhinitis;
• in some cases, birds have conjunctivitis;
• young animals refuse to eat, cuddle up to heat sources;
• the kidneys and ureters are affected - along with this, diarrhea begins, and the bird itself looks oppressed.

Treatment Methods

As soon as the diagnosis of "infectious bronchitis" is made, quarantine is introduced due to the incurability of the disease. A ban is introduced on the movement of products obtained from birds and for sale. Regular disinfection treatments are carried out in all rooms where chickens were kept. Spraying aerosols containing chlorturpentine, Lugol's solution, aluminum iodide, etc.

Preventive measures

Incubation material must be obtained from healthy stock. If chickens were purchased at a poultry farm or from a private breeder, they need to be quarantined for 10 days (time for the development of a latent form of the disease). Vaccination helps prevent the development of the disease. Breeding birds must be vaccinated before laying begins.

colibacillosis

Coliinfection occurs not only in laying hens, but also in other birds that are kept on the farm. The disease occurs due to pathogenic Escherichia coli. At the very beginning, the internal organs are affected. With a poor unbalanced diet, unsanitary conditions in the premises for birds, as well as in walking areas, leads to the development of kaolibacteriosis. The acute course is typical for young animals, the chronic form in adult livestock.

Symptoms:

• refusal to eat, strong desire to drink;
• the bird is lethargic, indifferent to what is happening;
• the temperature rises;
• breathing difficulties, wheezing is heard;
• the peritoneum becomes inflamed, there may be diarrhea.

Treatment Methods

An accurate diagnosis is required. Treatment is carried out with the use of antibiotics: terramycin, biomycin, which are mixed with food. Spraying of sulfadimezin is used, an additive to the diet of multivitamins.

Preventive measures

Compliance with sanitary and hygienic procedures, freshness and balancing of the diet.

It's important to know! The disease is transmitted to people, most often in an acute form.

Mycoplasmosis

It is a chronic respiratory ailment, maybe both in chickens and in adult livestock. Mycoplasma excites diseases and is a special form of life, located between the kingdom of viruses and bacteria.

Symptoms

• breathing difficulties, wheezing, the bird sneezes and coughs;
• mucus and liquid discharge from the nasal cavity;
• the membrane of the organs of vision becomes inflamed, redness is visible;
• some birds develop indigestion.

Treatment Methods

Before starting treatment, it is necessary to accurately diagnose the disease. Unhealthy livestock must be destroyed. With mild depletion or conditional health of the individual, antibiotics are used. It is necessary to introduce oxytetracycline or chlortetracycline into the diet at the rate of 0.4 g per 1 kg of food for 7 days. Then a pass is made for three days and the treatment is repeated. It is acceptable to take other medicines.

Preventive measures

On the 3rd day after birth, chickens need to drink a solution of tilan (0.5 g / l, drink for 3 days). It is recommended to repeat prophylaxis every 56 days. The birdhouse is equipped with good natural ventilation or additional equipment is installed.

It's important to know! The disease does not harm a person. In humans, mycoplasmosis is of a different kind. The chicken form is distributed exclusively between birds.

smallpox

Symptoms

• identification of general weakness and signs of exhaustion;
• difficulty swallowing;
• the air from the lungs of a bird has an unpleasant odor;
• the presence of red spots on the skin, they then combine and become yellow-gray;
• the appearance of scabs on the skin.

Treatment Methods

The success of treatment can only be if it is carried out at the onset of the disease. Skin with lesions is wiped with furatsilin in the form of a solution (3-5%) or boric acid (2%), the use of galazolin is recommended. For internal use, biomycin, terramycin, tetracycline are used for 7 days. The diseased herd must be destroyed so that the disease does not spread.

Preventive measures

Strictly comply with hygienic and sanitary requirements. Carry out regular cleaning and disinfection activities in the premises for birds, you also need to process inventory.

It's important to know! For humans, the disease is not dangerous.

Newcastle disease

It is characterized by damage to the central nervous system, respiratory system, and the digestive system. In another way, Newcastle disease is called pseudoplague or atypical plague. You can get infected through sick or recently recovered individuals, food, water, droppings. Transmitted by air. Most often, the disease occurs in young chickens; adult flocks with pseudoplague do not show symptoms.

Symptoms

• temperature rise;
• sleepy bird;
• mucus accumulates in the oral and nasal cavities;
• chickens begin to spin, trembling of the head is noticed;
• the bird falls on its side, its head throws back;
• the work of the motor apparatus is disrupted;
• there is no swallowing reflex;
• blue comb.

Treatment Methods

There is no cure. The death of the livestock occurs after three days, in some cases, it is 100%. If a diagnosis of Newcastle disease is made, it is better to destroy the herd.

Preventive measures

Sanitary standards must be strictly observed. In some cases, vaccination can be saved. There are three types of vaccine containing live, laboratory attenuated, live attenuated in nature, and inactivated pathogens.

Destroyed birds or dead from pseudo-plague must be burned or buried in special places, throwing corpses with quicklime.

It's important to know! The disease is dangerous for people, has an acute form of the course.

This disease is viral, primarily affects the stomach and respiratory system. It has a severe form of flow, and leads to mass death of livestock. Special immunity in chickens up to 20 days of life.

Symptoms

• heat;
• diarrhea;
• earrings and comb have a bluish color;
• the bird is lethargic, sleepy;
• difficulty breathing, wheezing.

Treatment Methods

There is no cure, as soon as signs of the disease appear, the herd must be slaughtered. The corpses are burned or buried in cattle burial grounds at great depths and covered with quicklime.

Preventive measures

Strict observance of sanitary standards, as well as regular disinfection of bird rooms and inventory tools. As soon as bird flu is detected, the bird is rejected and slaughtered.

It's important to know! Represents a great danger to people because of the ability to mutate. Can develop in the human body.

Gumboro disease

It is a dangerous viral infection that most often affects chickens up to the age of 20 weeks. The bag of Fabricius, the lymphatic system become inflamed, hemorrhages occur in the muscles and stomach. In addition, the immune system suffers, which is why there is a high mortality rate.

Symptoms

• the disease has no pronounced characteristic signs;
• diarrhea, the cloaca may be pecked;
• the temperature in the aisles of the norm in some cases decreases.

Treatment Methods

The disease is incurable, the death of the livestock on the 4th day. As a rule, the diagnosis occurs post-mortem. The destroyed livestock is buried in a specially designated place, covered with quicklime, or burned.

Preventive measures

Sanitation must be strictly observed. Acquired livestock must be quarantined.

It's important to know! Does not pose a danger to people.

Laryngotracheitis

It is an acute infectious disease. It happens not only in laying hens, but also in the rest of poultry. The larynx, trachea become inflamed, in some cases there may be conjunctivitis. The method of transmission is airborne. In sick and recovered birds, immunity develops for a long time, but laying hens continue to be carriers for several more years.

Symptoms

• breathing difficulties;
• inflammation of the mucous membranes;
• decrease in egg productivity;
• conjunctivitis.

Treatment Methods

When the form is started, the methods of treatment do not give a result. With the help of tromexin, the condition of sick birds can be alleviated. The drug dissolves with water 2g/l on the first day, 1g/l thereafter. The course lasts until recovery occurs, but should not be less than five days.

Prevention measures

Compliance with sanitary conditions. Carrying out vaccinations. Planting in the quarantine room of the acquired livestock.

It's important to know! It poses no danger to people.

Invasive diseases

• heterokidosis;
• defeat by downy eaters;
• ascariasis;
• coccidiosis;
• knemycodosis.

coccidiosis

Symptoms

The symptoms of coccidiosis are similar to intestinal infections. The bird begins to refuse feed, diarrhea may occur. Feces are green and may have blood clots. Individuals quickly lose weight, observe anemia, egg productivity disappears. After some time, positive changes in the health of birds begin, but then the signs return.

Treatment Methods

Anti-microbial drugs are used for treatment. The most commonly prescribed nitrofuran series or sulfonamides. This is done by a veterinarian.

Heteracidosis

Symptoms

There are no clear signs.

Treatment Methods

Ascariasis

Also caused by nematodes.

Symptoms

Leads to weight loss and emaciation. Decreased egg productivity. In some cases, there is bloody discharge from the mouth and diarrhea.

Treatment Methods

The use of antihelminthic agents, and the deworming of livestock.

Downy eaters

Symptoms

When infected, there is a decrease in appetite, weight loss, lack of egg production.

Prevention measures

The device of dry baths, in which they put a mixture of dust, sand and ash. Also, this mixture can be poured into the chicken coop.

It is important to carry out disinfection measures, process equipment and premises for birds.

Knemidokoz

The disease is caused by feather mites.

Symptoms

Most often they live among the feather cover on the limbs. Chickens actively peck at these places, after which swelling occurs on the legs. In addition, damage is formed at the site of pecking, on which crusts grow over time.

Treatment

It is necessary to treat livestock, and the sooner the better. First of all, it is treated with stomazan, neocidon. Processing only external.

If signs of a secondary infection appear in the pecked place, then it is necessary to start treatment with antibacterial drugs.

Other diseases

This list of diseases is far from complete. There are diseases that are directly related to the wrong approach to feeding. These include:

• gastritis;
• inflammatory processes in the goiter;
• uric acid diathesis

The goiter can become inflamed because foreign objects, spoiled food get there. It also occurs with a lack of vitamin A. To begin treatment, it is necessary to identify the source.

If a foreign object is found, surgical intervention will be required. If the reason is different, then a therapeutic diet is prescribed for the bird, milk or flaxseed broth is drunk, potassium permanganate is used to wash the goiter, soda is added to the shelves in the form of a five percent solution. Treatment is carried out until complete recovery occurs.

When uric acid diathesis (gout) occurs, a diet that lacks proteins is necessary. By the way, mainly adult birds are susceptible to the disease.

The feed should contain a lot of green feed, carotene and vitamin A. Their deficiency is very easy to recognize. It manifests itself in paralysis of the limbs, refusal to feed, motionless sitting in one place, goiter or intestines can become inflamed.

Gastritis is diagnosed by signs such as the presence of ruffled feathers, diarrhea and a weakened state of the bird. For treatment, a diet, a tincture of hemp seed, and a weak solution of manganese are used. As a preventive measure, fresh green fodder and vegetables are used.

Another common disease that occurs when improper feeding, or lack of vitamins, is salpingitis (inflammatory processes in the oviduct).

The most important symptom is egg production that has an irregular shape, lack of shell, and then the ability to carry eggs disappears.

Treatment consists in normalizing the diet, supplementing with vitamins, and monitoring the laying hens so that the matter does not end with a prolapse of the oviduct. If this happens, then you need to call a veterinarian who will set it in place.

Proper feeding with quality food helps to avoid alopecia (severe feather loss, which is not associated with feather mites).

Video. Diseases of chickens

Diseases do not spare anyone, any animal can get sick and die if you do not pay attention to obvious symptoms in time and do not provide the right assistance. Domestic chickens very often die because the owners did not pay attention to certain signs and did not help cure the disease. For example, diarrhea in chickens is a phenomenon that is quite difficult to immediately notice. Therefore, household utensils should be treated carefully. This article will look at the most common chicken diseases, their symptoms, and suggest treatment options.

The main diseases of laying hens

Knowing about the possible diseases of chickens is necessary for everyone who breeds them or keeps them to get eggs. The main reason for the appearance of the disease is the improper maintenance or nutrition of chickens.

colibacillosis

This disease is not only for adult laying hens, but also for young ones. The main symptoms are lethargy, thirst and fever. The infection affects the respiratory tract, so when you take the chicken in your hands, you will clearly hear wheezing. And when moving, they will only intensify. Characteristic wheezing is clearly observed in young chickens, but in old ones - this can not always be observed. This is where specialist help will be needed.

If the diagnosis is established, then it is necessary to immediately proceed to treatment. To do this, it is enough to give penicillin. According to veterinarians, a small an overdose of this drug contributes to the development of immunity to the disease.

pasteurellosis

This disease takes the lives of chickens at 2-3 months. But most of all, an adult bird dies from it. Symptoms of the disease: lethargy, fever, thirst, the chicken practically does not move, and mucous fluid flows from the nasal openings, diarrhea, the chicken constantly ruffles and raises its feathers. The scallop and earrings of such a chicken will darken and acquire a bluish tint. If this infection is not treated immediately, then the mortality of the entire livestock is guaranteed.

This infection is treatable only in the first stage. They are given tetracycline 1-2% aqueous solution. Some veterinarians recommend using norsulfazole solution. These drugs are added to the feed at 0.5 g at a time.

salmonellosis

This disease is more pronounced in a young chicken, but there are cases of damage to an adult. Typical symptoms are: lameness on one leg, conjunctivitis, increased tearing, breathing problems. When it is already impossible to save the bird, it simply falls on its side or back and dies. Leg diseases in chickens are not uncommon, so you need to watch them very carefully.

If you have such a case, then immediately proceed to the treatment of the remaining chickens. Them antibiotics can be given chloramphenicol, chlortetracycline or sulfanilamide. Small doses of drugs are added to the feed and given to chickens for at least 10 days.

Newcastle disease

This disease does not choose between young or old birds. The disease proceeds very quickly, most often the death of the bird is simply stated. A sick bird constantly sleeps, does not eat anything and has a fever, a liquid will come out of its beak, which smells bad. The chicken can hardly breathe, because the mouth is full of this mucus, the beak is constantly open. The breath of this bird is accompanied by croaking sounds. Before death, the comb and earrings turn blue in the bird.

Until now, veterinarians have not developed methods for treating this disease. Their only advice is to destroy all available poultry. But, if you take the risk and the chicken survives, then she gets immunity, but the offspring will be constantly susceptible to this disease.

smallpox

This disease mainly affects young chickens. Specific outgrowths-pockmarks appear on the skin of the bird. More often they are centered on the head or cloaca and if you do not start treatment in a timely manner, then the growths increase, unite with each other. In the early stages, the neoplasms are yellow in color, but over time they become dark brown.

After a few weeks, these pockmarks begin to bleed, harden, and fall off. Further, such formations appear in the mouth of the animal, the bird stops eating, it is difficult for her to breathe.

In order to avoid hardening of pockmarks, it is necessary treat affected areas with any fat or glycerin. If you paid attention in the later stages and the disease affected the oral cavity, then it is necessary to pour a small amount of 1% iodine into the beak. You can wash with a decoction of chamomile. Such a bird must constantly have access to water.

This disease occurs in 70% of adult birds. The main symptoms are lethargy, decreased or complete lack of appetite. The chicken drinks a lot of water.

This infection is treated only with antibiotics, they are diluted with water and injected intramuscularly.

Tuberculosis

This infectious disease affects not only people, but also chickens. Not only the lungs are affected, but all internal organs. The cause of the disease is unsanitary conditions in the chicken coop. The main symptoms of the disease are: severe thinness, pallor of the comb and earrings. This disease is not treatable. infected chickens must be destroyed, and clean and disinfect everything in the chicken coop.

Noncommunicable diseases

Goiter atony

This disease is inherent only in laying hens. The reason for it is an unbalanced or untimely diet. If the owners feed chickens with poor quality compounds, then they can accumulate in the goiter and create obstruction. It is easy to determine this disease, just try to touch the goiter of the chicken, if it is hard and sagging for a long time, then the chicken is sick. The death of a chicken occurs suddenly and instantly, the goiter blocks the airways and the jugular vein.

It is not difficult to treat this disease. It is enough to drip a few milliliters of vegetable oil through a probe into the goiter. Further, a light massage of the hardened goiter is performed and turn the chicken upside down, slowly remove all the contents. After this procedure, veterinarians recommend pouring a solution of potassium permanganate into the goiter.

Gastroenteritis

A chicken can get sick at any age. Due to poor nutrition, problems with the digestive tract begin, diarrhea and weakness appear.

Given that these symptoms may be the cause of an infectious disease, it is best to invite a veterinarian for an examination. If the diagnosis is confirmed, then it is enough to feed the chicken with a balanced diet for several days.

cloacite

The cause of the disease is also malnutrition or violations in the norms of keeping chickens. But here the cloaca becomes inflamed. There have been cases that the cause of the disease may be problems with the release of eggs.

As a treatment, washing the cloaca with manganese is used, preliminary cleaning of pus, and after that, lubricating this place with petroleum jelly, anesthesin and terramycin. To avoid this disease, experts recommend introducing natural greens into the feed, carrots or root vegetables.

Keratoconjunctivitis

This disease affects chickens that are kept in barns where the manure is poorly cleaned or very rarely cleaned out. From fresh litter ammonia vapor is released into the air, which are the cause of inflammation of the eyes and bronchial tract. The main symptoms are: watery eyes, dirty and wet feathers, yellow masses may collect on the eyelids.

For treatment, it is necessary to clean the shed well of chicken manure and ventilate it well. Rinse eyes with chamomile decoction.

Avitaminosis

This disease is more common in laying hens that are kept in cages. They do not eat natural food, only mixtures. Conjunctivitis, minimal body weight, weakness, feather loss can be observed.

For treatment, it is necessary to balance the diet and introduce natural herbs into the diet.

Sharp objects in the stomach

A chicken is an unpredictable bird, especially if it has a will. Chickens peck at anything. Therefore, very often the cause of death is the presence of a sharp object in the stomach, which breaks it.

The same can happen with goiter, rough parts of the grass, small bones can form a blockage of the goiter, which will lead to death.

Hen can't lay an egg

Such situations are often found in young laying hens. She starts darting around the chicken coop, her comb turns bright red. It is necessary to help such a chicken is necessary or she will die. It is enough to do the following:

• heat a bucket of hot water and hold it over steam for about half an hour, then lubricate the passage with petroleum jelly;
• if the chicken egg is too large and stuck in the cloaca during demolition, then it can be pierced with a syringe, pull out the liquid and slightly pressing down on the shell, carefully remove it from the passage;
• if the egg begins to come out across, then the chicken is laid on its back and any oil or petroleum jelly is injected with a syringe, and then the egg is gently pushed out.

Eggs without shell

For treatment, carbon tetrachloride is used at the rate of 5 mg per animal.

Inflammation of the ovaries

The cause of the disease is a blow or a sharp fall from a height. Yolks that are born inside can develop and begin to rot. Obvious signs will be irregularly shaped eggs, two yolks in one shell, a thin shell. Such a bird often dies.

Frostbite of limbs

In winter, during severe frosts, often combs, chicken legs get frostbitten and these parts subsequently die off. At the first symptoms of frostbite on the legs of a chicken, it is necessary to rub these areas with snow and smear with iodine.

To get rid of them it is necessary to regularly clean the chicken coop chlorophos solutions and karbofos emulsion. During processing, chickens should not be indoors and after - about 2-3 hours.

Be sure to change perches and straw where they lay eggs.

The fight against downy eaters

This disease affects a large number of adult birds. If you do not provide timely assistance, then the disease only progresses. Symptoms: shortness of breath, white-yellow spots on the crest. This disease is not treatable. These birds are being killed.

Aspergillosis

This is a disease of the respiratory system. Symptoms: the bird sneezes, the beak turns blue. Treatment only with copper sulfate, which is introduced into the diet.

Preventive measures to prevent the disease

If you do not want to lose a bird, then periodically perform the following preventive measures:

• do not combine young and adult birds, this can cause the death of both one and the other;
• if the bird is sick, urgently put it in a separate room;
• if the chicken is not subject to treatment, it must be destroyed and burned;
• be sure to treat the chicken coop with disinfectants at least once a month.

Provide chickens with proper care and a balanced diet and most of the above diseases will not bother your bird. Diseases of chickens and their treatment are the most important topics for those who breed these birds.

Many hobbyists, having decided to breed chickens, out of inexperience put their entire household and other poultry at risk of infection. Diseases of chickens and their treatment, and more often just the slaughter of sick livestock, often drive the economy into a financial hole. Especially if the owner has purchased broilers for later sale or an expensive breed of chickens for breeding.

Eimeriosis chickens

Eimeriosis is the main invasive disease of broiler chickens, and their treatment is the main problem for veterinarians on a poultry farm. This misfortune does not pass by small private farms. Eimeriosis affects young chickens under the age of 6 months.

Important! The more common name for this disease is coccidiosis.

Symptoms of the disease

The first symptoms of the disease appear a week after infection. This is expressed in a decrease in appetite. With further development, chickens completely stop eating, become inactive. Chickens are constantly cold and huddle together in an attempt to keep warm. Of the more specific symptoms of chicken eimeriosis, one can note:

• diarrhea with mucus, and sometimes with drops of blood;
• pale comb and wattles;
• ruffled feather cover.

In very young chickens under the age of 3 months, the course of hens' eimeriosis usually passes in an acute form. Death occurs 2-3 days after the onset of the first symptoms of the disease and reaches 70%. In adult chickens, coccidiosis usually resolves in a chronic form and the owners of domestic chickens do not notice the disease. Therefore, adult chickens are often carriers of the disease.

Symptoms of chicken eimeriosis are very similar to signs of histomonosis, borreliosis, trichomoniasis and pullorosis, so the final diagnosis is made on the basis of laboratory tests.

Treatment of the disease

At the first symptoms of the disease, coccidiostatics are soldered to the entire population. For broilers, drugs are used that prevent the development of immunity, since these chickens are kept for up to 3 months, after which they are slaughtered for meat.

For future laying hens and replacement herds, drugs are used that do not prevent re-infection and the development of immunity to coccidiosis. An extreme way to develop resistance to disease: leave the chickens to their fate. But ill chickens grow slowly.

Disease prevention

Preventive measures to prevent the disease imply the usual cleanliness of the owner:

• regular cleaning of inventory;
• regular bedding change;
• scheduled disinfection;
• exclusion of litter ingress into water and feed.

But no matter how clean the owner is, a chicken walking on the street is at risk of infection. Therefore, in addition to sanitary measures, chickens are vaccinated against eimeriosis or constantly soldered with coccidiostatics in lower than therapeutic doses.

Newcastle disease

A viral disease often referred to as Asian bird plague or pseudoplague. To some extent, it is dangerous even for humans. Infection with the virus does not pose a serious threat to people, but it can provide a slight indisposition. There are several strains of the virus:

• highly virulent- 100% death, internal bleeding;
• respiratory - 80-90% of the death of chickens, often - pneumonia;
• neurotropic - 100% death, cause encephalitis.

The source of the disease are latent carriers of the virus and wild birds. In the external environment, the virus is quite stable, remaining in rotting corpses for up to 3 weeks.

Symptoms of the disease

Due to the different strains of the virus, the symptoms of Newcastle disease in chickens are very diverse:

• gray, green or yellow feces;
• high temperature (up to + 44 °С);
• mucus in the nose, eyes and mouth;
• conjunctivitis;
• soft tissue swelling around the eye;
• swelling of the neck and chest;
• si snubness of the comb;
• problems with coordination of movements;
• thinning of the eggshell up to its complete disappearance;
• paralysis of paws and wings;
• trembling of the head;
• twisting of the neck.

Pathological anatomical examination reveals numerous small hemorrhages.

The final diagnosis is made in the laboratory, differentiating pseudo-plague from other infectious diseases.

Important! There is also an atypical form of the disease.

Such pseudo-plague affects young animals in herds with the active use of antibiotics.

Prevention and treatment of the disease

Treatment for Newcastle disease has not been developed and is not cost effective. Sick chickens are slaughtered and burned.

Prevention of the disease consists in eliminating the introduction of the virus into prosperous farms through:

• hatching egg;
• new chickens;
• inventory;
• service staff;
• bedding;
• feed.

Mandatory to fulfill the requirements of veterinary and sanitary control. When a disease is detected on the farm, quarantine is introduced.

chicken plague

An acute viral disease that causes damage to the respiratory and digestive organs. Depending on the strain, the mortality rate of chickens from classical fowl plague is 10-100%. The natural reservoir of the disease is wild migratory birds.

From domestic species, almost all birds, including quails and guinea fowl, are ill with influenza. A feature of the virus is that it feels good even in 10-day-old embryos. That is, he gets there from the body of a laying hen, and the owner of the farmstead has every chance to bring the plague to his home along with the eggs.

Important! If a chicken has been ill with the flu and remains alive, it will acquire immunity only to this strain of the virus.

If another strain appears, the same chicken will get sick again.

Symptoms of the disease

After infection, it takes 20-48 hours before the first symptoms of the disease appear. The onset of the disease is manifested by refusal to feed, depression, thirst, and a decrease in egg production. The hens stand ruffled, with their heads bowed and their eyes closed. The mucous membranes are swollen, the nasal openings are closed with exudate. Body temperature 43-44 °C. Breathing is rapid. In addition to these symptoms, there are also:

• brown-green feces;
• diarrhea;
• arena movements;
• convulsions;
• neuroses.

Shortly before the case, the cyanosis of the crest appears in chickens. Death occurs within 24-72 hours.

Prevention and treatment

There is no treatment. Due to the high contagiousness of sick chickens, they are immediately slaughtered. For prevention, the influenza vaccine and the observance of sanitary and veterinary standards in farms are used. In private farmsteads, all livestock are slaughtered.

Infectious neurogranulomatosis

He is also Marek's disease, neuritis, neurolymphomatosis, paralysis of birds. Causes BM herpesvirus, which can spread:

• by air;
• through the litter;
• bedding;
• eggs.

Airborne transmission of the virus is the main route of infection for chickens.

Symptoms of the disease

Marek's disease mainly affects young animals aged 3-24 weeks. It is believed that the incubation period of the disease is relatively short and fits into 2-8 weeks after infection. But owners of domestic chickens claim that BM appears quite late. Literally, their advice to other chicken farmers affected by the disease sounds like “you can start broilers, but they will not have time to live before the onset of clinical symptoms.”

Important! Such “helpful” tips help keep the virus in the coop for many years.

The duration of the incubation period depends on the age of the bird, resistance to the virus, and the sex of the chickens. The maximum period is more than 5 months. The younger the chicken, the shorter the latent period of the disease.

The disease is characterized by a classic and acute course. Acute appears "suddenly" in farms already infected with the BM virus. Symptoms are similar to avian leukemia. Mortality 9-46%.

Classical proceeds in chronic and subacute forms. Symptoms of the classic form:

• a change in the color of the iris in chickens to gray;
• stellate or pear-shaped pupil;
• paresis;
• lameness;
• paralysis.

Lethality 1-30%. The death of chickens occurs 1-16 months after the onset of the first symptoms. You can have time to kill a bird for food. The final diagnosis is made on the basis of laboratory and pathological studies. The photo shows internal tumors in chickens with Marek's disease.

Prevention

There is no cure for the disease. For prevention, chickens are vaccinated with live vaccines. But the main preventive measure is to buy chickens and eggs only from prosperous farms, and not from the hands of the market.

Laryngotracheitis of chickens

A highly contagious viral disease of chickens that causes choking, conjunctivitis and inflammation of the mucous membranes of the respiratory tract. The virus is very stable in the external environment. Depending on air temperature and localization, it is active from 12 hours to 9 years.

Important! The latter figure is unattainable under normal conditions; this requires dehydration of soft tissues in a vacuum.

Maximum survival in vivo: 86 days at 2-4°C in tracheal mucus.

Symptoms of the disease

The incubation period is from 3 to 30 days. Symptoms and mortality vary depending on the form of the disease:

• hyperacute - cough with blood clots and mucus, death 50%;
• acute - wheezing, cough, hemorrhagic inflammation of the larynx, decreased egg production, death occurs in 15% of cases;
• subacute and chronic forms - cough, conjunctivitis, wheezing, shortness of breath, mortality 5-7%.

In all cases, chickens die from suffocation. The level of mortality depends on the conditions of detention and feeding. With quality content, most chickens recover. Under adverse conditions, up to 80% of the livestock die. The diagnosis is made on the basis of laboratory research and autopsy.

Prevention and treatment

There is no specific treatment for the disease. Antibiotics are used to prevent complications. The basis of prevention is the prevention of the introduction of the virus. Chickens are also vaccinated with live vaccines.

Infectious bronchitis of chickens

Highly contagious viral disease. Stability in the external environment is average. The maximum period of virus activity is up to 90 days in litter and carcasses. In drinking water, it is deactivated after 11 days. It is transmitted from a sick bird to a healthy one through mucus particles, droppings, by direct contact.

Symptoms of the disease

The incubation period is 1.5-10 days. Symptoms in chickens and adult hens are different from each other.

Mortality of chickens up to 33%. With nephritic-nephrotic syndrome, the mortality rate of chickens reaches 70%. An adult bird often survives, but after an illness in laying hens, egg production drops to 40% and the egg shell remains soft. In fact, keeping sick chickens becomes unprofitable.

There is no cure. Prevention: purchase of clinically healthy chickens, disinfection of hatching eggs and poultry houses, vaccination with a dry vaccine. In large farms, when infectious bronchitis is detected, the livestock is destroyed.

Infectious bursitis of chickens

A highly contagious viral disease of chickens, characterized by damage to almost all body systems. Other names for the disease:

• infectious nephrosis birds;
• Gumboro disease;
• avian nephrosis-nephritis syndrome;
• infectious bursal disease.

With IBD, bags of joints, intestines, and joints of the legs become inflamed. In the external environment, the virus persists for up to 2 months.

Symptoms and prevention

The incubation period is 1.5-2 days. The course of IBD can be acute or latent. In acute, the disease affects 100% of vulnerable individuals. Broilers aged 2-11 weeks are especially susceptible to the disease. First symptoms:

• oppression;
• chills;
• diarrhea;
• sudden refusal to feed;
• signs of CNS damage;
• inability to move.

Sick chickens "sit on their paws." Later, emaciation, watery white droppings, indigestion are observed. Usually, mortality in the acute course of IBD is up to 6% of diseased chickens, but with poor maintenance, the number of deaths can be 40% or more.

With a latent course of IBD, it “disguises itself” as symptoms of secondary diseases, which makes it difficult to diagnose. The final diagnosis is made after clinical studies of the biomaterial.

There is no cure. Prevention: stocking the herd only with chickens from prosperous farms. According to the instructions, vaccines against infectious bursitis are used.

Egg drop syndrome

Adenovirus disease, due to which egg production decreases and the quality of the shell and the shape of the eggs deteriorate. It is believed that the virus is carried by ducks, which themselves are resistant to it. Adenovirus does not harm chicken breeds intended for meat, but significantly reduces profits on egg farms.

Symptoms

The syndrome is a disease of chickens without special signs, it is difficult to find a characteristic picture of their symptoms, since the disease often does not manifest itself in chickens, and shell defects can occur for other reasons.

From the initial symptoms note:

• prostration;
• disheveledness;
• diarrhea.

At the late stage, the cyanosis of the earrings and comb, watery cloudy egg white, the laying of deformed eggs for 2-3 weeks, and a decrease in productivity up to 30% appear. With cellular content, productivity is slowly restored.

The diagnosis is based on the results of bioassays and pathological studies. Exclude other infectious diseases.

There is no cure. Prevention: compliance with the standards of maintenance and timely vaccination.

Pullorosis-typhoid

A bacterial disease that affects all chickens of all ages. In adults, pullorosis leads to inflammation of the ovaries and oviducts and yolk peritonitis. In young animals, the gastrointestinal tract and respiratory organs are affected.

There is a disease with unsanitary conditions in the chicken coop and incubator. Passed on to the chick from the laying hen. Symptoms appear 1-2 days after hatching. Mass death for 5-7 days. After that, the disease passes into the chronic stage. Bacteria vectors: rodents, staff, arthropods.

Important! Particularly susceptible to typhoid fever are broiler chickens raised on traditional homemade feed: boiled eggs, millet, cottage cheese, and so on.

Symptoms of the disease

The acute form occurs more often in chickens. Her symptoms:

• white diarrhea;
• blockage of the cloaca;
• weakness;
• apathy.

Sick chickens are detected by these symptoms on the 3-7th day after hatching. Mortality is low, but young animals that have been ill are stunted.

Important! By six months, sick and healthy chickens are compared in size.

In adult laying hens, typhoid occurs without symptoms. Periodically decreases egg production. There is yolk peritonitis, oovaritis, intestinal upset, blue crest. The diagnosis is made in the laboratory.

Prevention and treatment

There is no cure for chickens with typhoid symptoms. Conditionally healthy people are treated with antibiotics. Prevention: compliance with sanitary norms and quality maintenance and feeding.

Poultry colibacillosis

An acute disease caused by the intestinal bacterium Eshecheria coli. Other names for colibacillosis:

• eschecheriasis;
• coliseptimia of birds;
• colidiarrhea;
• colisepsis.

In chickens, the disease occurs in the form of coliseptimia. In this case, there is damage to the air sacs, lungs, pericardium, liver, joints. Enteritis with concomitant diarrhea does not always occur. In acute course, the percentage of deaths reaches 30%.

Prevention and treatment

Treatment begins with the slaughter of sick chickens and cleaning the chicken coop from the droppings. Conditionally healthy livestock are soldered with broad-spectrum antibiotics. Prevention: good housing conditions and high-quality feed.

Pasteurellosis young

Symptoms

The incubation period lasts from several hours to 2-3 days. Symptoms of the disease depend on the form and nature of the course. Pasteurellosis can have 3 forms:

• intestinal;
• chest;
• edematous.

The symptoms of all these three forms are different.

The course of the disease may be;

• super-sharp;
• sharp;
• subacute;
• chronic.

The rate of death of chickens depends on the type of course of the disease: from sudden death with superacute to 5-7 days with subacute. In chronic cases, chickens do not die, but their existence is complicated by mucus from the nose and eyes, rhinitis, and inflammation of the intermaxillary space.

Important! Treatment of sick chickens is not carried out.

Only prevention is possible: strict quarantine, compliance with sanitary requirements, vaccination of chickens against pasteurellosis.

chickenpox

Viral infectious disease. Avian pox has three strains: chicken, pigeon, and canary. Symptoms of smallpox in chickens depend on the form of the disease:

1. Skin. Pocks on the head in the region of the crest, earrings, beak, eyelids.
2. Diphtheroid. Films on the mucous membranes, wheezing, the beak is open.
3. Mixed. On the skin of smallpox, on the mucous membranes.
4. Catarrhal. Rhinitis, sinusitis, conjunctivitis.

The percentage of deaths in chickens with smallpox is 15-60%.

Treatment

In poultry farms, treatment is not carried out. In private courtyards, symptomatic treatment:

• antibiotics to prevent complications;
• pockmarks soften and remove the crust;
• ulcers are lubricated with drying preparations;
• the nasal cavity is washed with a solution of boric acid;
• conditionally healthy chickens are vaccinated with a dry vaccine.

It is better for owners of private houses not to wait for the arrival of smallpox and to vaccinate in advance.

streptococcosis

Infectious disease caused by micrococcus. Most often, infection occurs by air. Infection through the umbilical ring at hatching is also possible.

The course of the disease can be acute, subacute or chronic. Main symptoms:

• depression;
• from glued eyes;
• drowsiness;
• disheveledness.

Sometimes there may be cramps of the limbs and neck, cyanosis of the crest. Diarrhea and breathing problems may occur.

In the chronic course of the disease, joints and beards become inflamed, paresis, diarrhea, catarrh of the upper respiratory tract occur. There is a refusal to feed and, as a result, exhaustion. Egg production decreases or completely stops.

Treatment is carried out with antibiotics, and prevention is aimed at increasing the resistance of the chicken body to the pathogen.

Important! Chickens are more resistant to streptococcosis if they have enough vitamin A in their bodies.

Leukemia of chickens

The disease is caused by an RNA-containing oncovirus. Symptoms are non-specific:

• scallop anemia;
• diarrhea;
• exhaustion;
• decrease in egg production.

There is a version that the predisposition to leukemia is inherited.

There is no treatment. Preventive measures: use of hatching eggs obtained from old hens. Such chickens are less susceptible to leukemia. Suspicious chickens with clinical symptoms are slaughtered.

Tuberculosis

The disease in chickens is rare and usually occurs in a chronic form with blurred symptoms. Infection occurs from a carrier of the active form of the disease. Most often these are wild birds.

Symptoms of chicken tuberculosis:

• yellowness of the mucous membranes and skin;
• diarrhea;
• exhaustion;
• lethargy;
• decrease in egg production.

Occasionally, tumor-like formations on the foot and lameness are observed.

The final diagnosis is made in the laboratory. There is no cure, sick chickens are slaughtered. From preventive measures: livestock vaccination and compliance with sanitary and veterinary requirements.

ornithosis

Another name: psittacosis. A contagious bacterial disease transmitted to humans through the air. The disease is caused by a bacterium called chlamydia. The pathogen can exist in chicken manure and nests for 2-3 weeks. The pathogen reservoir is domestic and wild birds. The infection spreads very quickly among the inhabitants of the house.

The infection most often enters the body through the mucous membrane of the respiratory tract, less often through the small intestine. Symptoms of ornithosis and other infections are similar:

• loss of appetite;
• apathy;
• conjunctivitis;
• diarrhea;
• hoarse breathing;

In the chronic form, convulsions and paralysis can develop.

Important! Ornithosis treatment is designed for humans only.

With a high risk of human infection, chickens are not treated. All livestock is destroyed at once.

Omphalitis

A disease characteristic of mammals. This is a bacterial inflammation of the umbilical wound. Contrary to information on the network, chickens do not get sick with omphalitis during the week. If something went wrong when hatching, they will die within the first 2 days. More often they die not from omphalitis, but from streptococcosis. But streptococci do enter the chicken's body through the umbilical wound while still in the incubator. Therefore, disinfection before a new batch of eggs is mandatory. Treatment of chickens is impractical.

coccidiosis

Encephalomyelitis

A disease that affects the spinal cord and brain. May be concomitant with some other types of infection affecting the central nervous system. Infectious encephalomyelitis in chickens is a viral disease that is 100% fatal.

Symptoms of the disease:

• impaired coordination of movements;
• convulsive twitching of the neck;
• loss of ability to stand with a blockage on one side;
• paralysis.

There is no treatment.

Sinusitis

Inflammation of the mucous membranes in the sinuses. Symptoms are: mucus from the nose and swelling of the soft tissues under the eye. Sometimes swelling is a brewing purulent fistula.

In chickens, it is rarely an independent disease. This is usually one of the symptoms of another, more serious illness. If it is certain that it is only sinusitis, the treatment is carried out with a broad-spectrum antibiotic, which is given along with the feed.

Nutrition related diseases

If there is no need to worry about this moment at poultry farms, since this is the concern of livestock specialists, then private traders should pay close attention to the usefulness of the chicken diet. In the household, diseases of chickens often occur due to improperly selected feed and violation of feeding rules.

Dyspepsia

In fact, the stop of the digestive tract. With dyspepsia, chickens lose the ability to digest and assimilate food. The causes of dyspepsia can be:

• poor feed quality;
• whole grain feeding;
• too early introduction of difficult-to-digest types of feed into the diet of chickens;
• dirty water;
• very frequent food changes(from grain to silage or fresh grass);
• hypovitaminosis.

Symptoms of dyspepsia and any other chicken disease are similar:

• oppression;
• weakness;
• lowered head;
• half-closed eyes;
• diarrhea of ​​all colors possible for chickens.

Mild dyspepsia treatment is not required. It is enough to review the diet and conditions of detention and remove suspicious factors. To treat the disease in severe form, antibiotics of the tetracycline group and sulfa drugs are used.

Goiter atony

Occurs if the goiter is clogged with food, and the chicken cannot eat. The reasons why the goiter is clogged: whole grains or prolonged starvation of chickens. The grain, swelling, closes the passage from the crop to the stomach. With prolonged starvation, the chicken eagerly pecks at the food and can clog the goiter even with ready-made granules.

Symptoms of a clogged goiter:

• refusal to feed;
• lethargy;
• goiter very hard;
• outflow from the beak of a liquid with a sour smell;
• later stench from throat;
• with the development of the disease, difficulty breathing.

If you do not take action, the chicken will die. On poultry farms, the treatment of chickens with atony is not practiced. But there are 2 popular ways:

1. If the chicken has pecked on dry granular feed, water is poured into it with a syringe and the goiter is massaged so that the feed softens into a liquid porridge. Carry out the procedure several times until the problem disappears.
2. The second method is shown in the video below. Apply if the chicken is full of whole grains.

Salpingitis

A non-contagious disease that occurs as a result of intensive oviposition or when young hens lay eggs that are too large. With a non-infectious origin of salpingitis, its symptoms:

• difficult oviposition;
• secretion of liquid mucous masses from the cloaca.

Subsequently, the cloaca bulges outward.

Important! Salpingitis can be one of the symptoms of other diseases.

At the beginning of the disease, the hen lays irregularly shaped eggs. At the end, oviposition stops completely. There is no treatment.

Gastroenteritis

Reason - poor quality food. The symptom is diarrhea. Treatment is with antibiotics in advanced cases. In an easy version, it is enough to give the chickens high-quality feed and clean water and add probiotics to them.

cloacite

Non-contagious inflammation of the cloaca that occurs due to violations of the conditions of detention and feeding. In chickens, the course is severe and usually ends in death. Treatment of conventional chickens is unprofitable, they are slaughtered. An expensive bird can be saved with antibiotics and vitamin supplements.

Symptoms of cloacitis:

• refusal to feed;
• thirst;
• apathy;
• exhaustion;
• loss of feathers in the abdominal region;
• with the progression of the disease, the cloaca turns outward.

Important! Since cloacitis is associated with a violation of the diet, it affects the entire livestock.

If one sick chicken is found, the treatment is carried out by the entire population.

Avitaminosis

It often occurs when chickens are kept in winter due to a lack of fresh greenery and sun. Symptoms of beriberi are similar to signs of dangerous infectious diseases, so it is necessary to differentiate different types of diseases. With beriberi in chickens can be:

• diarrhea;
• lethargy;
• exhaustion;
• feather loss;
• pecking;
• inflammation of the joints;
• anemia of the scallop, earrings and mucous membranes;
• loss of orientation.

Treatment of beriberi is carried out by feeding chickens with vitamin and mineral premixes. The same is done for prevention.

Diseases of chickens in winter

In winter conditions, due to the overcrowding of livestock and the relatively high temperature in the chicken coop, favorable factors are created for the development of almost all possible diseases. But the most well developed at this time:

To eliminate beriberi and helminthiases, a well-composed diet and deworming of chickens on schedule is sufficient. With the other two types of diseases it is more difficult.

fungal diseases

In the absence of ventilation and high humidity, mold begins to develop in the chicken coop. With a large amount of mold and reduced immunity, aspergillosis develops in chickens. The causative agent is the fungus Aspergillus. In the acute course of the disease, the percentage of deaths reaches 50. The disease manifests itself in young animals at 3-4 weeks, in adult chickens - as it should.

Symptoms of the disease in chickens:

• exhaustion;
• weakness;
• decrease in egg production.

Important! Young animals can become infected while still in the egg if the incubator is not disinfected.

The disease resulting from aspergillosis is aflatoxicosis, that is, poisoning with aspergillus toxins. Symptoms of the disease are the same as those of aspergillosis, plus muscle spasm and loss of feathers. There is no cure for the disease.

• ticks;
• bird bugs;
• pereedami.

When chickens are affected by bedbugs, local inflammation occurs at the site of the bite, and “water” bubbles form. Chickens become shy. The condition of the chickens is oppressed, they constantly sit ruffled. Egg production is sharply reduced. With severe irritation at the site of the bite, self-pecking is possible. During the day, the bugs hide in the crevices, and they can only be detected when examining the livestock in the evening.

When affected by feathers, chickens begin an intense self-pecking. Feathers fall out, bare spots are inflamed. To detect a feather infestation, it is enough to catch a bird, spread the feathers and admire the running insects.

Ticks

Red chicken mites behave like bedbugs, with which they are often confused. This species also lives in the crevices of the chicken coop and produces mass attacks on chickens. Due to bleeding, chickens become lethargic, reduce egg production. The comb and earrings turn pale.

Microscopic mites live in follicles and feather rods. Scabies settle under the skin and scales of the paws. When infected with these forms of mites, chickens develop scabies, they begin to peck themselves into blood. Feathers fall out.

When paws are affected by ticks, a specific white crust forms on the metatarsus. The basis of the crust is made up of raised scales.

Prevention and treatment

Treatment of chickens is carried out with insecticidal preparations for animals. Any that you can buy at a pet store will do. But after the treatment of chickens, it is also necessary to carry out disinfestation of the entire room.

On the video, the main diseases of chickens and drugs for their treatment.

Conclusion

Diseases of chickens and their treatment is a very voluminous layer of poultry farming. The main thing that an ordinary amateur chicken breeder needs to know is the rules for protecting livestock from the introduction of diseases from the outside. If a disease occurs on the farm, you need to contact a veterinarian for an accurate diagnosis.
