Symptoms and treatment of diseases of broilers


A considerable number of owners of farms and subsidiary farms, buying broiler chicken, think that it will be cheaper and more reliable to grow such chickens in terms of using safe growth stimulants. And many have already gone this way.

It turned out, however, that a certain proportion of quite surmountable drawbacks are added to these advantages, one important place among which is occupied by diseases of broiler chickens, whose symptoms are easily recognizable, and treatment methods tested by many years of experience.

Broiler resistance to disease

When broilers suddenly begin to sneeze and wheeze in a new poultry farmer, the first thought is not about how and with what to treat them, but why it happens at all - after all, it seems to be generally accepted that the broiler chickens are resistant to diseases.

In fact, it is generally accepted not a fact, but a myth about this stability. Broiler species of birds (not only chickens) are specially bred hybrid breeds, besides gaining weight at an unnatural rate for nature.

As a result, they are inevitably whimsical to conditions of detention, the deterioration of which entails some specific diseases.

Therefore, when chickens sneeze and wheeze, you need to concentrate and choose what to treat them correctly.

The owner's approach should be similar to other manifestations of diseases, and even to the mortality of broilers, that is, it is necessary to quickly determine why broilers chickens die and what measures need to be taken urgently. Most of the diseases that cause chickens to die are non-infectious, so there is no need to do something to protect against infections.

Care should be taken about rational feeding to prevent hypovitaminosis.

Noncommunicable Diseases of Broiler Chickens: Symptom Detection and Treatment

Considerable experience of growing broiler chickens clearly recorded the most dangerous temporary stages of their growth in terms of susceptibility to disease. These are:

  • first five days,
  • six days starting from the 20th day
  • six days starting from the 35th day.

It was during these periods, when the chickens increased the sensitivity of the digestive system, attention to the behavior of the birds must be exacerbated, and care should be especially careful.

A severe disorder of unstable digestion, called dyspepsia, explains well why broilers die in critical periods. The digestive tract, the stomach, the intestines of the chicken do not yet have the necessary number of enzymes, and their acidity is below the required level. Among the causes of dyspepsia, except, in fact, the weakness of the digestive system itself:

  1. Products that even slightly contain rot or mold.
  2. Poor water.
  3. Products that require too much energy and time to digest (fats, as well as barley and rye grains).
  4. Abundant feeding after suffering fasting.
  5. Sharp change of feed type.
  6. Use as feed protein, silage, freshly cut grass.
  7. Deficiencies in the nutrition of hen-producing embryos.

With dyspepsia, chicks become lethargic. At the weakened chickens eyes do not open, necks are pulled out, they badly eat. Well, diarrhea in broiler chickens shows that they need to be treated.

If diarrhea in chickens acquires characteristic colors (brown, whitish or green with yellowness), and even foam and mucus are present in the feces, then treatment of the dyspepsia that occurred (and its whole point - to eliminate the reasons just listed) should be prompt so as not to lose livestock completely.


If broilers wheeze, then the threshold of the chicken coop crossed bronchopneumonia, and it is necessary to decide what to treat with it. The wheezing is accompanied by a generally intense breathing of birds. In addition, the symptoms of bronchopneumonia are expressed:

  • neck extended forward
  • beak open all the time
  • poor appetite against the background of a missing view and sitting instead of active movement,
  • ruffled plumage,
  • accelerating weight loss.

In this situation, it is important to prevent the glut of air in the room with carbon dioxide. Without sufficient oxygen in the surrounding atmosphere, the disease can worsen, leading to pulmonary edema or abdominal dropsy.

If, despite the preventive measures, broilers still began to wheeze, the veterinarian, having made the diagnosis, will tell you what to treat them with. The drugs used for bronchopneumonia, are known, more than others - erythromycin, gentamicin, belspirara oral. Of the relatively new means - enroxil.

Important!The dosage must be coordinated with the veterinarian.Experts do not distinguish sneezing as a characteristic feature of only bronchopneumonia, associating it primarily with infectious diseases. In this regard, you should not bother yourself with additional reflections on why broiler chickens still sneeze and what to treat them. You just need to do two things in sequence:

  1. treat chicken nostrils with streptocidal powder,
  2. Seek advice from a veterinarian who will make an accurate diagnosis.

Hypovitaminosis A

Vitamin A is extremely important for the body of the chicken (aka retinol), which is, firstly, an antioxidant, secondly, plays a significant role in maintaining the normal functioning of the immune system. Vitamin A is necessary for good vision and normal development of bone tissue.

Therefore, deciding what to do if broilers do not grow well, the first thing to do is to check if there are any other symptoms of hypovitaminosis A:

  1. night blindness, i.e., twilight vision disorder,
  2. inattention to feed,
  3. wagging when walking against the background of general passivity.

Feed the body with retinol helps feed enrichment grass meal, as well as carrots.Important!On the basis of hypovitaminosis A, diseases of the nervous and digestive systems can develop.

Hypovitaminosis B

Paralysis of the wings and legs, increased goiter and drooping of the head are characteristic signs of hypovitaminosis B.

In addition, broilers, in the body which lacks this important component, look, as a rule, chickens, reject much of the food and slowly increase in growth. It becomes clear why the chickens are lowering their wings and than they need to be treated immediately. Herbal flour and green, meat and fish supplements will add vitamin B to the chicken body.

Hypovitaminosis D

Metabolism involves normal calcium-phosphorus metabolism, and, accordingly, the sufficiency of vitamin D (calficerol) in the body. Chickens in this regard are no different from other cubs - the disappointing outcome of hypovitaminosis D is the emergence and development of rickets, which makes the bones of the skeleton too soft.

The issuance of germinated oats, grass meal, preparations with concentrated vitamin E will help to cope with the disease. It is important to remember about the inadmissibility of the simultaneous use of the drug with vitamin E, fish oil, by chicks.

The lack of vitamins belonging to group B can cause the development of this form of hypovitaminosis in broiler chicks.

In such a situation, the poultry farmer may be worried: “How to treat broiler chickens if they are numb, look depressed, eat poorly, grow slowly?”. Also, the owner of the house is able to worry because of the questions: “Why are broiler legs taken away from broiler chickens, head thrown back, wings paralyzed, an increase in goiter is observed?”.

In order to fill the need for vitamins of group B and eliminate the problem of “failed legs”, the farmer should enrich the poultry diet with greens, meat, fish, and grass meal. Also practiced issue relevant vitamins, oil or water-based.

Broiler chickens are susceptible to various infectious diseases. Among the common diseases of young stockings, a particular danger is Newcastle disease, respiratory mycoplasmosis, white bacillary diarrhea, pullorosis, Marek's disease, coccidiosis.

A veterinarian who examined sick individuals may prescribe Tetrahydrovit for broiler chickens to ensure that they are able to cope with the situation. The use of the drug Trihopol for broiler chickens is practiced, the doses of which are calculated in strictly defined proportions.

The correct dosage of Trichopol for broiler chickens can only be prescribed by an experienced doctor. Even an experienced farmer should not engage in self-treatment of their winged wards.

Alben is very effective for broiler chickens, which is also issued in agreement with the veterinarian.

Due to the high risk of infectious diseases for broiler chicks, the owner of the house will need timely timely preventive measures.

Disinfection, prompt isolation of diseased birds, ensuring cleanliness of equipment, drinking bowls, feeders, good ventilation, whitewashing the room, monitoring balanced nutrition, and taking mineral and vitamin supplements to the bird will ensure high resistance of the young to possible infections.

A well-considered approach to keeping broiler chickens, the ability to identify their ailments in time, to carry out preventive measures, and the treatment of diseases will be guarantees for getting healthy, strong individuals. Subsequently, the work of the poultry farmer will be rewarded - the indicators of the meat productivity of its poultry will turn out to be beyond praise.

Diseases and treatment of broiler chickens

Broiler chickens are the most popular birds for keeping, both at home and on an industrial scale, for slaughter or for the production of eggs.

They are good because they grow quickly, give a good weight gain, are not very whimsical both in content and in feeding, but sometimes they are also susceptible to diseases.

About this topic, namely “the disease of broiler chickens” and will be discussed later in the text.

Major diseases and treatments

Often, broilers can suffer from a disease such as aspergillosis, that is, a viral infection that is caused by an allergen and affects the respiratory tract of a bird. It is most often caused by improper litter or unclean conditions.

This virus is bad because it appears at the slightest bird care error.
It is very difficult to treat it, sometimes even heavy antibiotics are needed, which are added to the food of broiler chickens.

Treatment of broiler chickens in this case either brings results, or the bird is subject to destruction.

You can do the prevention of this disease by making hard litter in which the causative agents of the disease cannot accumulate. Still need to monitor the cleanliness of the aviary and the room for the maintenance of broilers. It is necessary to do the cleaning 2 times a week, and this will be a defense against a large number of diseases, and not only this one.

It is also a harmful disease for chickens pullorosis, or, otherwise, chicken dysentery. She is ill mainly broilers aged up to three weeks. Chicks may become sick with it due to some stamps present on the cereals. This virus is not so dangerous and is amenable to easy treatment. It is only necessary to administer the sick sugar, dairy products and medicines from the category of septicides and antibiotics.

A big problem in birds, already of any age is salmonellosis. It is caused by the salmonella virus and infects the body of the broiler, which leads to weakness, deterioration, loss of mobility, etc. In some cases, the bird may die. By the way, this virus is dangerous for people, and it can be transmitted through meat.

In order to avoid it, it is necessary to specifically feed the chickens, as well as give them medicines aimed at destroying this retro virus. As a rule, all birds are cured and there are no further problems, because immunity is established. But in order. To check whether the bird is healthy, you need to do the necessary tests.

In some cases, the bird has a sharp decline in strength, and it even happens that broiler chickens fall to their feet. This may be due to a metabolic disorder or an improper diet. The chicks are also dying from immobility, so here it is necessary to apply measures.

The treatment of broiler chickens in this case is to put them on a strict diet. In the menu it is worth leaving only water and compound feed to which vitamins are added. Vitamins strengthen the immune system and give strength.

Compound feed should be used for young animals, and vitamins to give a wide variety, but not in large quantities, otherwise hypervitaminosis will begin.

After a week or two of such treatment, all broilers will run and flit "like a butterfly".

These were the main diseases of broiler chickens and their treatment methods. And remember, the disease is easier to prevent than to treat it.

Broilers: diseases and their prevention

In order for the rearing of broiler chickens to bear fruit, it is necessary to strictly observe all sanitary and veterinary measures, as well as to conduct a special program for broiler chickens, justified by scientific research. It is necessary to realize that diseases of broilers in the worst case can lead to the bankruptcy of certain poultry farms or farms.

Moreover, these birds need regular prevention of infectious diseases.

As they say, the one who is warned is armed! After all, the cost of carrying out all the necessary sanitary and veterinary measures pays for itself fairly quickly, and the costs of treating already diseased birds can be overwhelming, and sometimes even meaningless: for example, infection with avian flu "mows down" all the chickens.

Dangerous diseases of broiler chickens

The most dangerous for broiler chickens are respiratory diseases. If they were not prevented or cured in time, then almost all the broiler herds die.

Among infectious diseases affecting these birds, it is necessary to distinguish colibacteriosis, leading to a massive death of chickens (up to 55% of the population).

The so-called secondary infection and mycoplasmosis are both dangerous diseases of broilers.

Treatment and prevention of diseases of broiler chickens

Most of all diseases affecting chickens have a complex etiology. Despite this, the program (complex) use of modern antibacterial drugs greatly simplifies the process of treating broiler birds.

In special cases, well-conducted therapy allows veterinarians to take control of the epizootic situation (widespread disease), even with mycoplasmosis, colibacillosis and other infections of a bacterial nature.

The most common drugs used in the treatment of broiler chickens are "Tilokol", "Sulteprim", "Klindaspektin", "Spelink" and "Nifulin-forte". It is worth noting that all the components that make up the listed drugs were selected by veterinarians, taking into account the synergistic effect.

To prevent the majority of all possible diseases of birds is possible only with the use of complex programs, including the use of anti-bacterial, anti-mycoplasma, anti-parasitic and other prophylactic drugs. It is impossible to forget for a minute that broiler chickens are a living organism that requires increased attention.

Even the lack of basic hygiene can "mow down" more than half of the broiler hens.
