Cattle bronchitis is a common respiratory disease that occurs everywhere in the Russian Federation. Pathogenic microflora affects the respiratory tract, and in the absence of timely treatment, the disease can become chronic or cause serious complications.

How does bronchitis develop in cattle?

The disease is a bacterial infection of the bronchial mucosa. Also, pathogenic microflora can affect submucosal tissues. Most often, the cause is the animal's prolonged exposure to conditions of low temperature or high humidity. Risk factors include inhalation of dust, pollen, drugs, fungi, gases, and vapors. Most often, bronchitis develops in calves, since their immunity is not yet able to fight bacteria.

Types of disease

Bronchitis can develop in acute form within 1–2 days. In adults, as well as in young animals that have recovered from the disease, the disease can persist for many months in a chronic form. Based on the symptoms and degree of damage to the mucous membrane and tissues, the following types of this disease are distinguished:


  • microbronchitis;

  • macrobronchitis;

  • diffuse;

  • catarrhal;

  • fibrinous;

  • purulent;

  • putrefactive;

  • hemorrhagic.



Animals most easily tolerate macrobronchitis. No increase in temperature is observed. The nature of the cough changes from dry to wet within 2–3 days. Breathing is harsh vesicular, to which wheezing may be added on the 2nd day.

Microbronchitis is characterized by a weak but painful cough and an increase in temperature by 1–2 degrees. Breathing is vesicular, and moderate wheezing is heard in the affected areas. Shortness of breath develops.

The most common form is acute catarrhal bronchitis. IT develops quickly - on the first day the cough is dry, on the second it becomes wet, with copious exudate. Accompanied by bronchostenosis or bronchiectasis - narrowing or widening of the lumen of the bronchi. There is mucous discharge from the nose. The temperature rises, and on the third day signs of intoxication of the body are noticeable.

In addition to the main symptoms of cough and fever, bronchitis is often accompanied by, among other things:


  • fibrinous - fibrin effusion;

  • hemorrhagic - hemorrhages;

  • purulent and putrefactive - with corresponding secretions from the bronchi.

Treatment regimen for bronchitis in calves and adults

The use of one of the NITA-FARM antibiotics solves the problem of pathogenic microflora, eliminating the very cause of the disease. We offer the following drugs:

  • "Azitronite". Broad spectrum antibiotic. The basis is azithromycin, an active substance with an effective bacteriostatic and even bactericidal effect. The drug helps destroy bacteria within several hours after the first injection. In total, two intramuscular injections are required with an interval of 24 hours.

  • "Nitox Forte". Developed for the treatment of respiratory diseases. It is based on oxytetracycline and flunixin, which continue to protect the body from re-infection for another 5 days after administration. One intramuscular injection is enough, and within an hour the drug actively destroys pathogenic microflora.

  • "Amoxigard". The newest antibiotic for the treatment of respiratory diseases in cattle based on amoxicillin and clavulanic acid. The course of treatment is 3–5 days, depending on the severity of bronchitis. One injection is given daily.

  • "Florox". The active substance, florfenicol, has increased bioavailability. It reaches its maximum concentration in the blood serum within 30–90 minutes. Administer twice with an interval of 48 hours.


To reduce fever and more effectively combat bronchitis, we recommend supplementing antibiotic therapy with Flunex, which is a non-steroidal anti-inflammatory drug.

To reduce intoxication and remove bacterial waste products from the body, we suggest using one of the following drugs - “Calcium borgluconate 20%” and “Caffeine-sodium benzoate 20%”.

To stimulate metabolism and quickly restore individuals after illness, it is useful to use one of the vitamin complexes - “Tetrahydrovit” or “Butofan”. They will help reduce the effects of stress on the body.
