Diseases of broilers and their treatment at home


Broilers are the same hens, only they are grown purely for meat and eggs. The difference is that they grow quickly and in 2-3 months can reach 1.5 kilograms.

But this of course will be only with appropriate care. In addition to adequate feeding and maintenance, it is imperative to monitor the health of the bird. Broilers, like chickens, are prone to infectious diseases, with the appearance of which all individuals can die.

Therefore, when detecting the first symptoms of the disease immediately proceed to the appropriate treatment. In this article we will take a closer look at the diseases of broilers and their treatment at home. We find out why broilers wheeze, sneeze, go blind and what to do.

Diseases of broiler chickens and how to treat at home

While breeding and growing broilers, it should be borne in mind that the bird is highly susceptible to various diseases, especially in the first days of its life up to one month of age. First of all, attention is drawn to the suspicious behavior of the bird. - lethargy, loss of appetite, apathy. Perhaps this is a temporary phenomenon and after a certain period the bird will again have an appetite and mood. But not always. Sometimes this condition worsens and causes severe symptoms. So how do you determine whether a bird is sick or not?

Often problems arise for beginners. In this case, pay attention to the first symptoms.

In addition, you should pay attention to the common symptoms that can be causes of infectious diseases:

What if chickens sneeze?

Let's start with the most common problem - why do chickens and chickens sneeze? Broilers can sneeze in different diseases, usually this symptom is caused by viral colds. It is better to call the veterinarian when sneezing occurs and to conduct an examination so that he has already established the cause. In the place where the birds are kept, all drafts, dampness should be eliminated.

It is advisable to install a ventilation system, install heaters. Lamps must be at a certain level above the heads of broiler specimens, but in no case at or below their level. Often, improperly installed lamps lead to overheating of birds, and then, when individuals leave for a while to eat, their body cools down and as a result they catch cold.

Treatment of broilers

Why are chickens sneezing and broilers chickens we figured out, now find out what to do. If sneezing has just appeared, then it is advisable to immediately powder the nostrils with streptocide powder. To do this, the powder is typed in cotton and thoroughly rubbed into the nostrils of the bird. This will prevent the spread of infection further into the bronchi and lungs. Additionally, broilers need to be fed with antibiotics - chloramphenicol and tetracycline. Add 1 tablet to 1 liter of water. Antibiotics are watered for 4 days.

But still, when sneezing occurs, it is worth referring to a veterinarian, because such a symptom can be the cause of dangerous diseases such as bird flu, aspergillosis, chicken pox and other serious diseases.

Why do chickens cough?

We now turn to the question of why broilers and chickens cough and what to do? Broilers can cough for different reasons. Sometimes cough causes cold due to drafts or increased dampness. In these cases, it is better to warm the house, install an additional heater and make adequate ventilation. Additionally, the bird is watered with vitamins and antibiotics.

But cough is not always accompanied by colds, this symptom can be the cause of a serious and even fatal disease. - bird flu, aspergillosis and other pathologies.

For the treatment of diseases of chickens suitable the following drugs:

Why do chickens wheeze?

And now let's look at what to do if chickens wheeze and even die. Wheezing, like coughing and sneezing, are accompanied by a cold. In these cases, the place where the broilers are kept is drafted and damp. If these faults are detected, the house is restored to normal, and additional heating facilities are installed.

The bird is given vitamins and antibiotics until the symptoms disappear.
But one should not be sure that wheezing, coughing, sneezing are signs of a cold. Quite often, a symptom indicates the occurrence of a serious disease that a veterinarian can determine. And if you start a disease, the bird may start to die.

The appearance of wheezing in adult broilers

Why chickens diarrhea?

The appearance of diarrhea can be the first signal that the bird is infected with infectious diseases. It is worth paying attention to the composition and type of liquid stool. If it has a bright mucous with impurities, and then a greenish color appears, then it indicates the presence of infection.

In these cases, it is necessary to immediately provide appropriate treatment, because the infection can instantly hit all the livestock. Broiler chickens begin to carry in such infectious diseases as salmonellosis, colibacillosis, bird flu.

Birds runny nose usually occurs because of a cold, but not always. Usually, when a runny nose occurs, a full inspection of the hen house is done, and all possible drafts and dampness are eliminated. Also, when the cold, birds are given vitamins and appropriate antibiotics.

When a rhinitis occurs, they go to the veterinarian, he examines and if there is a serious disease, he provides appropriate treatment. What diseases can be accompanied by a runny nose: colicbacteriosis, Marek's disease, chicken pox, bird flu and others.

Symptoms of foot diseases in broilers

Sometimes birds can hurt their legs, this symptom is determined by the behavior and gait of broilers. Individuals can simply fall in place, with their legs moving apart. This is a signal that the bird has some serious illness that has led to leg problems.

Together with the disease of the legs there is a poor appetite, lethargy, weakness. When this condition appears, you should immediately contact a veterinarian, because foot problems are the cause of serious pathologies. Often foot diseases are observed with salmonellosis, rickets, Marek's disease.

Broiler foot diseases

What to do if chickens start to blind in one eye and breathe?

Sometimes broilers get blind. Chicken can go blind even in one eye. Blindness is the cause of serious infectious lesions, with the appearance of which it is necessary to immediately provide appropriate treatment. Otherwise, the infection can instantly infect other individuals.

Blindness occurs with salmonellosis, Marek's disease.
However, it is not enough to know the reasons, you need to have an idea about the treatment of serious diseases. Many pathologies can cause serious harm up to the death of the entire livestock. Therefore, to prevent unpleasant consequences should provide appropriate treatment in time.

Colibacteriosis: antibiotic treatment, prevention for chickens and adults

This is a dangerous disease that affects all individuals completely. The fact is that the causative agents of colibacillosis are constantly present in the environment. Failure to observe hygiene can lead to the active development of bacteria, which at the same time will affect almost all the internal organs of individuals.

Symptoms of the disease:

  • disorders of the digestive tract,
  • appetite disappears,
  • the occurrence of fever,
  • sluggish and depressed.

For the treatment of colibacillosis using antibiotics - terramycin and biomitsin. These funds are added immediately to the feed in powder form. Together with antibiotics, it is recommended to give vitamins every day and premixes together with feeding 1-2 times a day. The treatment is carried out 4-5 days before full recovery.

To prevent this disease, only fresh and balanced feed is introduced into the broiler diet. For the prevention of vaccination do the entire chicken population from this disease.

Colibacteriosis in broilers

Salmonellosis: what is it, how to cure chickens and adults

Salmonellosis is a disease of the gastrointestinal tract. The causative agents of the disease are Salmonella bacteria. It is transmitted by airborne droplets from affected birds to healthy ones. Often birds become infected through food. This infection affects juveniles.


  • the eyes become swollen and watery,
  • the cloaca is inflamed,
  • there is no appetite during heavy drinking,
  • diarrhea occurs
  • legs swell up
  • in chickens, growth and development are slowed.

How is the treatment and prevention
As soon as the salmonellosis is diagnosed, they immediately begin treatment. Treatment is carried out with a course of furazolidone and streptomycin. For chicks, it is recommended to carry out prevention - vaccination is done with immune serum.

Veterinary experts recommend to immediately kill the bird after salmonellosis treatment. If the disease has occurred in at least one individual, the rest of the bird is watered with a solution of chloramphenicol.

Salmonella Broilers


This is a viral disease that affects the respiratory tract of young individuals. Treats the most dangerous infections.


  • state of apathy and lethargy,
  • wheezing,
  • sometimes there is coughing and sneezing,
  • no appetite.

Treatment and Prevention
This infection is treated only with antibiotics. Drugs and dosage are prescribed by a veterinarian.
Preventive measures should be aimed at improving conditions of detention. It is possible that drafts and dampness are present in the hen house, so this should all be eliminated. The room needs to be warmed, it is advisable to install a heater and adjust the ventilation system.

Aspergillosis in broilers

This infection is caused by a bacterium called Bacillus pullorum. It is very difficult to determine this disease, because at the first stage it almost does not manifest itself and can begin to develop in an egg with an embryo.


  • the occurrence of white diarrhea,
  • rapid and labored breathing,
  • depletion of young individuals occurs, broilers often fall,
  • birds have constant thirst.

How to treat and prevent
Affected individuals are put in isolated rooms and treated with biomitsin. All broilers, regardless of whether they are sick or not, add furazolidone to the feed.

As a preventive goal, constant airing of broiler houses is carried out. It is also necessary to isolate infected individuals in time.

Pulloz at broilers

This disease occurs in chickens. It appears due to the lack of calcium and vitamin D.


  • in chicks, their legs are denied and they fall on them when walking,
  • there is a slowdown in growth and development,
  • nestlings become depressed, lethargic, apathy appears.

Treatment and Prevention
During treatment of this condition, vitamin preparations are prescribed. Various premixes with high calcium content are added to the feed.

Be sure to follow the preventive measures - it is not desirable to contain a large number of young animals in one cage. In addition, you need to conduct periodic walks in the fresh air.

Rickets in broiler chickens

Marek's disease: what it is, treatment, care and prevention for chickens at the age of one month

This pathology is mainly found in adult broilers. The virus affects the nervous system and the eyes of birds.


  • there is a modification of the iris of the eye and the pupil. As a result, comes full blindness
  • coordination of movements and motor functions is disturbed. Broilers have sore legs and they limp when walking,
  • during illness, goiter paralysis occurs, which leads to complete exhaustion,
  • mucous membranes become pale in color.

How to treat and prevent
Since this is a serious and dangerous disease, it cannot be cured, therefore it is important to make an accurate diagnosis. After identifying the disease, the bird must be slaughtered immediately.

Bird flu

This is a dangerous viral infection. It affects the respiratory tract and the gastrointestinal tract.


  • cough, runny nose, sneezing,
  • high body temperature,
  • state of apathy and lethargy,
  • diarrhea.

How to treat and prevent
This disease is not treatable. After the detection of bird flu, the bird immediately hacks.

As a preventive measure, strict adherence to hygienic and sanitary standards of poultry keeping is necessary It is worth remembering that bird flu is especially dangerous for the human body.

Infection of broiler chickens with avian flu

Chicken Pox: Growing Healthy Chickens

Chicken pox is spread by rodents and skin parasites. The causative agent of the disease has a high survivability in the environment. The disease affects the internal organs and the mucous membrane of the eyes.

Excellent preparations for the treatment of diseases of broilers:


  • sneezing, runny nose, cough,
  • in the open areas of the body, clear red spots may occur, which are subsequently converted into scabs,
  • from the affected birds is an unpleasant smell,
  • affected individuals experience heavy breathing and difficulty in swallowing,
  • there is a state of weakness, lethargy and depression.

How to treat and prevent
This disease is treatable only in the initial stages. Therefore, you should not immediately slaughter the bird, and carry out medical procedures with the help of glazolin, boric acid, furatsilina solution.

As a preventive measure, it is necessary to periodically disinfect and clean the house.

Diseases of broilers are almost the same as diseases and infections of chickens. The only difference is the spread of infection in broilers is fast, This is due to the fact that the birds are contained in a limited space. For this reason, it is imperative to carry out regular check-ups at the veterinarian and carry out appropriate prevention.

Chicken disease

Diseases of broiler chickens make the poultry farmer worry from the first days of young stock, so they need increased attention and special care from the moment they hatch. Experienced bird breeders noted that the risk group consists of chicks from 0 to 5, from 20 to 25 and from 35 to 40 days of life. In these periods of chick development, broilers are most vulnerable.

Note! If you see that one or a few chickens are sick, immediately remove them from healthy chicks. Such a measure will help prevent the spread of the disease and preserve the bulk of the young.

Broilers chickens die mostly for several reasons, eliminating which can increase the chance to raise a large and healthy bird with a large meat yield in the final stage. The main diseases of broilers that occur most often.

A disease of the gastrointestinal tract, to which only hatched chicks are prone. Their digestive system is not yet fully formed, so babies need proper specialized nutrition with the gradual introduction of new products into the diet. Otherwise, the chick will become sluggish, weak, will begin to pull the neck and constantly keep your eyes closed.

Proper nutrition can help prevent dyspepsia, but if the disease has already manifested itself, purchase BioMos. It will remove toxins from the body of broiler babies. The drug is diluted in the feed at the rate of 2 g per 1 kg of food in the first 2 weeks of life, then its amount is increased by 1 g for one week. Monthly chickens for the prevention add to 1 kg of feed 0.5 g of the drug.

Chickens suffering from dyspepsia suffer from diarrhea (see how to treat diarrhea in broilers at home). Excrements can have mucous impurities and particles of undigested food. Very often during dyspepsia chicks become bald.


Infection is caused by a virus and adversely affects the respiratory tract of chicks. It is characterized by a sluggish state, wheezing, a complete lack of appetite. Treatment of the disease is often successful and includes antibiotics.

Most often, aspergillosis occurs when the conditions of the chickens are disturbed - drafts provoke its occurrence, especially in winter.

Rattles in broiler chicks

Often, poultry farmers turn to veterinarians because of wheezing in broilers while breathing. In addition, there is an apathetic condition, poor appetite, developmental delays. All these symptoms indicate the development of colibacillosis.

Most often colibacillosis chickens inherit from their parents, which is a consequence of non-compliance with sanitary standards in the broiler henhouse. The disease is treatable with Ampicillin and other antibiotics, but poultry farmers still note high mortality of infected chickens.

Adult Broiler Diseases

In adults, the digestive system and a strong skeleton are already properly formed, so they are resistant to many diseases affecting chicks. But even among adult broilers, the entire livestock mortality is observed due to diseases that are dangerous not only for chickens, but also for other domestic animals.

Marek's disease

Viral disease, which is a common cause of death of the entire population of broilers. Today there is no way to cure a disease. If Marek's disease is found in a hen, then it should be slaughtered immediately and the carcass burned, as the virus may remain even in feathers. Дополнительно требуется комплексная чистка курятника.

Симптоматика болезни Марека:

  • поражение глаз, вызывающее слепоту,
  • потеря ориентации в пространстве,
  • плохая координация движений,
  • musculoskeletal dysfunction,
  • blanching of mucous membranes.

In addition, due to the defeat of the nervous system, the goiter of birds often paralyzes, which leads to exhaustion and death.

As a preventive measure, veterinarians recommend vaccinating all young stock in a timely manner, and when buying chickens from hands, ask the seller for a vaccination certificate.


Bronchopneumonia refers to non-communicable diseases. The cause of its development can be hypothermia or exposure to rain, as well as an infection. Symptoms of bronchopneumonia include:

  • the appearance of wet wheezing when breathing,
  • nasal mucus secretion
  • lethargy,
  • loss of appetite.

In the absence of treatment, sick chickens may die within 2-3 days.

Newcastle disease

Newcastle Disease, also called the Asian Plague of Birds and Pseudotum, is an infectious disease that causes a virus from the genus of paramyxoviruses. It leads to the development of pneumonia, encephalitis and causes numerous hemorrhages in the internal organs.

The main symptoms of the disease:

  • lethargy,
  • loss of appetite,
  • temperature increase up to 44 ° С
  • lack of coordination, paralysis of the legs or neck,
  • Harkanie and cough
  • blurred eyes and conjunctivitis,
  • discharge of mucus from the nose and mouth
  • diarrhea.

If the disease occurs in the acute phase, it takes from several hours to several days from the onset of symptoms to the death of the bird.


Mycoplasmosis is an infectious disease caused by bacteria. Mycoplasma Gallisepticum. It affects the respiratory system and can occur both in acute and in chronic form. The main symptoms of mycoplasmosis in broiler chickens:

  • dyspnea
  • wheezing
  • lethargy,
  • loss of appetite,
  • in some cases, eyelid swelling and tearing.

Mortality is about 5-10%.

Principles of Disease Treatment

Some of the diseases of broilers are incurable, for others a specific therapy has been developed that can be used independently. The first group includes such infectious diseases as:

All chickens infected with one of these diseases are isolated and destroyed.

Other diseases are treatable:

  • antibiotics such as penicillin, terramycin, norfloxacin are used in bronchopneumonia,
  • salmonellosis is treated with furazolidone and streptomycin,
  • with pullorosis, antibiotic sulfadimezin can be used to treat
  • for the treatment of coccidiosis use drugs that prevent the development of the parasite - statil, zoalen, coccidin, dexox, aprolium, sacox, baycox and others,
  • Mycoplasmosis is treated with tylosin, tiamulin or enrofloxacin.

As you know, any disease is better to prevent than to cure. For diseases of broilers, this rule applies to the full. To reduce the likelihood of developing pathologies, it is enough to observe simple preventive measures.

It is necessary to provide the chickens with the optimum temperature and humidity, protect the bird from drafts, find the right nutrition that contains all the necessary nutrients, vitamins and minerals, as well as regularly carry out sanitary treatment of the room.

Do not forget about timely vaccination. Compliance with these recommendations will help protect the young from disease, which as a result will result in significant savings in time, money and nerves.

Who is the broiler and the reasons for its popularity

Many people believe that broilers are a special breed of chickens for growing for meat. This is not entirely true. The fact is that this is not a breed, but only a hybrid line, obtained as a result of crossing several meat breeds. Such a line cannot exist independently, without human participation, since artificially obtained characters are not preserved in the progeny. Therefore, each new generation of such birds requires an infusion of pure tribal blood. In addition, broiler crosses are bred among other types of pets: broiler ducks, broiler geese and guinea fowls. Recently, new varieties have also appeared, for example, indo-broilers. Thanks to the achievements of modern science: genetics and veterinary medicine, when using progressive methods of fattening and housing, a broiler chicken can increase its own weight in just a month and a half fifty times! At the same time getting a gain of one kilogram is achieved by feeding only two kilograms of feed! None of the pets can boast such excellent results. This is the main factors of the huge popularity of their cultivation, including in home gardens.

Dyspepsia: the young are weak, sluggish, eat poorly, diarrhea

The day old broiler still has an unformed digestive system - its acidity of the gastric secretion is lowered, it does not contain enough digestive enzymes. All this leads to the fact that with improper feeding in the first day of life of the chicks, a number of diseases of the digestive tract occur.

The causes of dyspepsia, in addition to an undeveloped digestive system, may be the feeding of moldy, sour or rotten feed, feeding of poor quality water, overfeeding after prolonged fasting, as well as the introduction of difficult to digest feeds (for example, rye, barley, fats, etc.) . A sharp transition from one feed to another or the introduction of large amounts of unusual feed (fresh grass, silage, protein feed) into the diet have a negative effect. Contributing factors to the development of dyspepsia are feeding defects in the maternal herd of chickens, with the result that a violation of embryonic development occurs. Predisposing factors to the spread of the disease are lack of vitamins and minerals in the diet, as well as errors in the content. As a result of the impact of these factors, the birds are disturbed by digestion, the feed is delayed, it begins to rot and causes severe poisoning of the body. Often, death eventually occurs (toxic dyspepsia).

Sick youngsters are weak, lethargic, poorly eats food, eyes are closed, the neck is slightly stretched. The main symptom is diarrhea yellowish-green, whitish or brown, frothy, sometimes with an admixture of mucus. Undigested food particles are found in the feces, the back around the cloaca is contaminated with feces. What should be done to prevent dyspepsia?

  1. A day before the arrival of the party of young stock, the room is heated to 32 degrees so that the litter material becomes warm. The chickens abdomen should not be allowed to cool - otherwise the contents of the yolk sac will dissolve poorly, the navel will not heal well, the digestive tract will slow down.
  2. Shortly before planting the chickens, the troughs are filled with warm clear water, to which ascorbic acid and glucose are added. Approximately 50 grams of glucose and 2 grams of ascorbinka per 1 liter of water. This will help prevent the growth of germs in the intestines that cause putrefactive processes, and contributes to the development of lactic acid beneficial bacteria.
  3. It is good to add a vitamin-mineral complex to weak individuals. For example, Forte Universal according to the instructions.
  4. They are recommended to be fed about six times a day with special foods in the form of small grains with a minimum content of complex proteins and fats (millet, oatmeal, low-fat cottage cheese, sour milk, acidophilus-yeast whey, etc.).
  5. Drinking water is replaced with aqueous solutions of weak des. preparations: 0.03% solution of baking soda or 0.02% solution of potassium permanganate.
  6. On the first day of life, feeds that contain most of the lime (limestone, chalk, eggshell, shell, etc.) should not be given to the young.
  7. It is good to use ready-made starter feed up to two weeks of age, and for the prevention of infections and feed poisoning, BioMos is introduced into the feed. It binds very well to pathogens and toxins and removes them from the body. They give it according to the following scheme: up to two weeks of age, 2 grams of the drug are added to one kilogram of food, the next two weeks they add 1 gram to 1 kilogram, and until the end of fattening, half a gram of the drug per kilogram of feed.
  8. A very good effect for the recovery of beneficial microflora after antibiotic treatment, as well as at an early age, is given by Bifidum-SCF drugs. It is given in the ratio of 5 doses per 200 heads. To do this, the contents of the package are diluted in water and given with food or added to drinking water.
  9. It is important not to forget that with outdoor cultivation and with the organization of feeding and watering of young stock, it is necessary to ensure free access to water and feed for each chicken. This is especially important when distributing feed with prophylactic drugs listed above. The norms of the front of feeding - 2.5 cm per head, watering - 1 cm per head.

Hypovitaminosis A: ruffling, refusal to eat, problems with coordination

Caused by a lack of retinol diet. When this occurs, a violation of the proper metabolism in the body. A large number of avitaminosis and hypovitaminosis, and in youngsters of two weeks of age appear often due to the fact that the eggs are defective due to the low content in the yolk of retinol and carotenoids.

In the first days of the disease, appetite deterioration, weakness, passivity, stunting, ruffled feathers are noted. Then various diseases of the digestive system, the respiratory system develop, sometimes the nervous system is affected. The signs of her defeat are the following nervous phenomena: a wagging gait, movements in a circle, chickens walk in zigzags or on stilts, they fall on their backs through the pelvis, etc. A characteristic symptom of this avitaminosis is a weakening of twilight vision, the so-called "blindness." For the prevention and treatment of retinol deficiency, feeds rich in them (grass meal, carrots, etc.) or special preparations and feed mixtures are introduced into the diet.

Hypovitaminosis D: growth retardation, diarrhea, convulsions, lameness

It is characterized by a failure of calcium-phosphorus metabolism. In adults, the bones soften, and in young, rickets develop.

It develops for quite a long time and is characterized by weakness, lethargy, stunted growth, loss of appetite, abdominal distention, diarrhea, softening of the bones and deformation of the bones. At the beginning of the disease, the bird does not walk well, there is lameness, trembling of the extremities, convulsions, thickening of the joints of the extremities and ribs, a disproportionate increase in the head, and then they cannot walk at all.

Sick youngsters are isolated in a spacious, bright room and walking is organized, the diet should be balanced in vitamin and mineral composition. Fish oil and concentrated preparations of calciferol are given to patients in doses that are twice the prophylactic.

Hypovitaminosis E: convulsions, movement in a circle

Chickens get sick more often at the age of 3-5 weeks from the moment of birth. Weakness, partial paralysis of the limbs, jerky twitching. They often move in a circle, there is a twisting of fingers, twisting of the neck, in a state of stupor, death occurs.

To prevent hypovitaminosis E, germinated oats, grass meal or concentrated preparations of this vitamin are introduced into the feed. It is important to know that it is impossible to give this vitamin along with fish oil - they are antagonists.

Hypovitaminosis B vitamins: growth retardation, dermatitis, conjunctivitis

They all develop against the background of a lack of one or another vitamin from this group in the diet. There are a number of symptoms that are characteristic of group B avitaminosis. These include:

  • The depressed state of the chicks,
  • Decreased appetite
  • Noticeable slowdown in growth
  • Various lesions of the nervous system (convulsions, drooping of the head, paresis, paralysis of the legs and wings, etc.),
  • Often there are various forms of dermatitis,
  • Digestion is impaired (enlarged goiter, "black tongue" with a lack of nicotinomide and other signs),
  • Various forms of conjunctivitis develop ("blood eye" with deficiency of riboflavin, for example),
  • Exhaustion often develops, leading to the death of the bird.

To prevent these serious diseases, green fodder, meat, fish, bone and grass meal, germinated grain are introduced into the diet of young, as well as modern complex vitamins, which can be both oily and water soluble. It is necessary to use them according to the instruction on application in the terms and in the doses specified in it.

The next large group of diseases that causes serious damage in growing and fattening broiler chickens is group of infectious diseases: viral, bacterial, fungal, etc. The percentage of cases of these infections has very high values, sometimes it reaches one hundred percent mark. Knowledge of the signs of the most common and difficult of them is an indispensable condition for the success of all poultry farms, regardless of their size. Let's get to know some of them.

Newcastle disease: birds diarrhea, sneeze and lose orientation

This viral disease is characterized by a high transmission rate and a large population coverage. Infection of the bird can occur intrauterinely, therefore infected chickens can already be hatched.

In a typical form, the main signs are high body temperature (up to 43–44 degrees), weakness, birds stop eating, lose orientation, most of the diseased have an expansion of goiter, and a fetid liquid begins to flow from the mouth. Feces become liquefied, mixed with blood, mucus and bile. Patients breathe, opening the beak, listening to a variety of sounds due to blockage of the upper respiratory tract, chickens sneeze, trying to cough up mucus, sometimes make "croaking sounds", then develop signs of disease of the nervous system. They are characterized by paresis and paralysis, which leads to a twisting of the neck, wings and tail sag, legs are affected. Chickens become passive, they become shivering, growth is delayed, keratoconjunctivitis develops, the crest and beard become bluish. The treatment is not developed and is prohibited due to the threat of infection. In large poultry farms, poultry are vaccinated against Newcastle's disease with special vaccines. Private owners do not emit such a vaccine, so the best protection for them is to buy chickens only in specialized farms with well-established veterinary and sanitary work.

Pulloresis of birds (bacillary white diarrhea)

Infectious disease, acutely occurring in chickens and in latent form - in adults.

Sick chickens are sluggish, there is no appetite, breathing is more frequent, there is profuse diarrhea — whitish litter with a bad smell. Sometimes the dung dries around the anus and closes it, dull feathers, disheveled. Often they come together in groups, squeaking plaintively.

If they were still infected in utero, then pullorosis develops with lightning speed and death occurs at an early age. In chicks up to one month of age, the disease is slow. But the mortality rate is still very high. In young animals at the age of 20 days, the subacute form is more frequent and chronic. Sick individuals begin to lag behind in growth and development as compared to healthy ones, but at the age of six months the birds who underwent the disease cannot be distinguished from the non-diseased. Specific treatment has not been developed, but the use of antimicrobial agents, especially the last generation, helps well for preventive purposes etc.). You can use biomitsin, furazolidone, terramycin, tetracycline, biovit, polymyxin and their derivatives. Do not forget that in the event of such a disease plan, it becomes especially important to monitor the sanitary condition of the litter and rooms, because its spread is promoted by dampness and poor sanitation.

Respiratory mycoplasmosis: respiratory disorders, rhinitis, broilers often die

Chicks have a loss of appetite, respiratory function is impaired. The death of young animals reaches 25%, adult birds - 5%. Chronic course causes exhaustion. Adult broilers stretch their necks, try to cough up exudate accumulated in their throats, rhinitis often appears. From the nasal openings mucus elapses, sometimes with an admixture of pus.

The main objective of prevention is the isolation of birds of different age groups to prevent re-infection. The treatment of the disease is not developed, therefore the infected bird is killed and burned.

Marek's disease: limping, visual disturbances, loss of appetite

The incidence among young stock can reach 85%. A generalized disease occurs by 8–20 weeks after disembarking chickens. The classical form passes slowly, resulting in lameness, overhanging of wings and tail, twisting of the neck. Sometimes there are half-pairs that end in recovery. A characteristic feature is a change in the color of the iris with partial loss of vision or complete blindness. Lost reaction to the light. Death can occur in 1 - 16 months after the manifestation of the primary signs of the disease. Mortality varies with this form from 1 to 30%.

The acute form is more pronounced and resembles leukemia. The disease occurs at the age of 30 - 160 days suddenly and is accompanied by a massive departure of the bird. В течении пары недель заражаются все особи, находящиеся в стаде. Основными признаками являются: парезы и параличи, нарушение работы пищеварительного тракта, похудение, потеря аппетита, упадок сил, необычное положение тела, головы, крыльев, ног, хвоста.

How to treat attack? Unfortunately, successful research has not yet been conducted.

Coccidiosis: drowsiness, pallor of code covers, convulsions and paralysis

Contagious disease that is caused by coccidia. They are sick young from 15 to 60 days.

Chickens move a little, they are drowsy, they sit with wings down, they stop eating, thirst, on the contrary, is increased, they clump together, the fluff and feathers are disheveled, without shine. Liquid manure, whitish-green or dark brown with blood. Comb and earrings pale, sometimes with a bluish tinge. There are failures in the nervous system, which are characterized by paralysis and seizures. Mortality is very high and sometimes reaches 100% of the mark. If the flow is less acute, then death occurs much less frequently. But, surviving, such individuals become "snook" - inhibited in growth and development.

Used for the treatment of drugs such as Baykoks, Koktsidiovit. They are added to food or water according to the instructions. They are also used to prevent morbidity and are introduced in the early stages of rearing. It is important to observe all the standards of poultry housing and feeding, especially to prevent dampness in the rooms. After all, coccidia reproduce very well mainly in the wet dirty litter, near the drinkers, and spread with contaminated equipment.

Aspirgillosis of broilers: lethargy, breathing problems, wheezing

The disease is caused by mold fungi. Their reproduction contributes to dirt, dampness, poor ventilation in the premises. Due to this, spores of the fungus enter the respiratory tract of birds and begin their development there.

In the acute form of aspirgillosis, the following symptoms are observed: the diseased move little, lag behind the herd, refuse to feed, their wings are lowered, their feathers are dull and disheveled. Then shortness of breath appears, patients open their beak. The disease in this form lasts from one to three days. Death reaches 100%.

Subacute for several delayed and lasts from 6 to 12 days.
