What kind of disease and what is dangerous

One of acute chronic infectious diseases, in which toxicosis occurs, is colibacteriosis. Most often, the disease affects the lungs, air sacs, liver, pericardium, and joints. If an acute form of the disease is present, up to 30% of young stock may die; if adults are ill, their productivity sharply decreases. The disease can affect not only birds, but also other domestic animals. At the same time, internal organs are affected, which leads to an acute course of the disease. Colibacteriosis is a serious disease that often leads to the extinction of the entire poultry population. Most often occurs with unbalanced nutrition, unsanitary conditions. At the first suspicion of the presence of the disease should immediately seek help from specialists.

What a farm bird strikes

Most often suffer from colibacillosis:

  • chickens;
  • ducklings;
  • goslings;
  • young turkeys;
  • pheasants.

Important! Since the infection can occur by airborne droplets, when a sick bird is detected, it is urgent to isolate it and treat the room in which it was located.

Also, the carrier of the disease are such birds as pigeon, crow, sparrow. Young animals under the age of 4 months have a high susceptibility to colibacteriosis.

Causative agent and causes of infection

Causative agent - E. coli, which is quite common in the environment and is always in the gastrointestinal tract of both humans and animals. The microbe is resistant to the environment, on earth it can last up to 204 days. When the chopstick is heated to 60 degrees, its destruction will occur after 1 hour, and when boiled - immediately.

Colibacteriosis can develop as an independent ailment, but sometimes it is combined with other viruses, leading to complications. Sick and ill animals are a source of infection that gives off the wand.

The highest concentration of microbes is in the feces.When animal feces contaminate food, water, litter. The young bird eats food, and thus the infection is carried out. Colibacteriosis in chickens may appear even at the stage of spitting through the infected shell.

Symptoms and course of the disease

The duration of the incubation period may be from several hours to 2-3 days. In acute colibacteriosis, the disease progresses rapidly, and the death of the bird soon comes. At first she becomes depressed, lethargic, sedentary, refuses food. There is a blue beak, intestinal disorders, feces has a yellow-green color. There may also be swelling, inflammation of the joints. With subacute and chronic course of the disease, the dangerous period lasts 2-3 weeks. There is profuse diarrhea, it becomes watery, white-gray in color, sometimes with blood or mucus. The feather coating does not shine, dirty.

Did you know? The name of the chicken "broiler" comes from the English word broil, which means "fry on fire."

After 2-3 weeks after the onset of the disease, dyspnea may occur, which may be accompanied by suffocation. Even if the young ones recover, they will develop poorly. Colibacteriosis is characterized by such pathological changes: hemorrhage in parenchymal organs and intestinal mucosa.

Diagnostics

If a diagnosis of colibacteriosis of chickens has been made, it is mandatory to assess the epizootic situation, and it is important to take into account the clinical symptoms. Also conducted laboratory tests that are subject to analysis.

In identifying the disease should take the following actions:

  • remove the affected bird from the room to stop the outbreak;
  • carry out mechanical cleaning and disinfection in the hen house. To do this, use a solution of alkali (3%) or bleach (3%);
  • making the slaughter of animals, conduct a thorough inspection of carcasses.
If pathoanatomical changes are present on the corpses, they must be destroyed.

Treatment

If you suspect that the bird has colibacillosis, you should not self-medicate. It is necessary to immediately remove the affected individuals and clean the coop from the feces.After that, you should immediately contact the veterinarian. Unfortunately, the pathogen does not respond to some drugs. Before you begin therapy, you should find out the sensitivity of the agent to the pathogen. Thus, you will not lose time using ineffective drugs.

When treating neomycin, it should be mixed with food (50 g per 1 kg of bird weight). Give the drug once a day for 6-10 days. When using biomitsin and tetracycline add 20 g of feed per 1 kg of poultry, levomycetin - 30 mg.

For treatment use antibacterial agents, such as:

  • chloramphenicol;
  • tetracycline;
  • furagin;
  • baytril;
  • gentamicin and others

Important! Personnel engaged in the cultivation and care of the bird, also regularly need to check for the presence of the pathogen.

The course of treatment is 5-6 days, after which it is worth 4 days to give the bird probiotics, and then again hold a fixing course with antibiotics. It is better to use other drugs. The highest efficacy of treatment can be achieved by alternating antibiotics, nitrofuran preparations and probiotics.

Prevention

Prevention consists in carrying out a number of organizational, economic, veterinary, sanitary and hygienic procedures. They consist in the normal feeding of animals, the use of feeds that do not contain pathogenic Escherichia and are stored in a room protected from rodents. It is also necessary to complete manning of chicken coops with a bird of the same age every 5–7 days, observe sanitary breaks, rules for the care and raising of animals, and timely carry out disinfection and deratization treatments.

Three times a day, eggs should be assembled and the shell should be disinfected with 1% hydrogen peroxide solution. It is recommended to carry out vaccination using the aerosol method when the young growth reaches the age of 70-75 days. After the procedure is completed, it is necessary to ventilate the room and turn on the light.

Did you know? The mass of feed that the broiler consumes is gradually converted to half the weight of the chicken.

It is imperative for the responsible poultry farmer to know how colibacteriosis is manifested in broilers, what symptoms are present and what treatment is used.Periodic preventive measures can protect the bird from this disease.
