Bronchopneumonia in calves: symptoms and treatment
In order for the meat-breeding business to be profitable, not only proper care and intensive feeding is necessary, but also the ability to recognize diseases and cure them in a timely manner. One of the most common diseases in calves is bronchopneumonia . In this article we will talk about the causes of its occurrence, symptoms, effects on the body and methods of dealing with this ailment.
What is this disease
Bronchopneumonia (catarrhal pneumonia) is a common disease among small calves. It causes significant economic damage to farms, since it is characterized by high mortality rates. Untimely treatment leads to intoxication of immature organisms and the development of irreversible processes in the respiratory system of animals
Reasons for development
Reasons that provokes the development of the disease in cattle:
- feed with a small amount of vitamins;
- accommodation of animals in poorly ventilated and uncleaned rooms on time;
- incorrectly matched pair for mating, which as a result gives offspring with weakened immunity and anatomical malfunctions;
- failures in the digestive tract.
Important! Observe the optimum temperature at the location of the calf. Hypothermia or overheating can trigger the development of the disease.
The mechanism of the origin and development of the disease
The disease is long and protracted. Initially, it affects the bronchi and develops throughout the bronchial tree. Treatment of a chronic form is difficult. It manifests itself in an acute inflammatory process in the upper respiratory tract, fever and swelling of the nasal mucosa. And only after 3 days does pneumonia with wheezing occur. In the acute form, pallor of the mucous membranes and pulmonary edema are observed. The disease most often occurs in calves aged 30 to 45 days.
Manifest depending on the intensity of the disease.
Develops up to 10 days. Expressed by lethargy and lack of appetite. If the calf is inactive and refuses to eat, take a closer look at it. Breathing through the mouth, watery eyes, mucus from the nose, which eventually becomes pus, are signs of the disease. A rare cough with a sharp sound is an indicator of the development of an acute form of bronchopneumonia.
Learn how to cure calves.
It is necessary to call a veterinarian as soon as possible and pass the necessary tests. An ailment determines an elevated white blood cell count. Keep in mind that if you ignore the treatment, the calf's health will deteriorate rapidly.
At this stage, the animal eats poorly, and therefore does not gain mass. Body temperature remains normal during the day, but rises by several degrees in the evening. The calf has shortness of breath. And diarrhea is a sign of the progress of the disease and its severity. This form of the disease develops from 2 weeks to a month.
An animal with a chronic form noticeably lags behind in development. It constantly coughs, mucus flows out of its nose, wheezing is heard in the lungs. Calves with chronic bronchopneumonia do not mate.
An accurate diagnosis can only be made by a veterinarian based on laboratory tests. Bronchopulmonary and biochemical tests are prescribed. An X-ray examination is also important, which in the presence of a disease shows a blackout in the lungs. Based on the results obtained, the doctor determines the degree of the disease and develops a treatment technique.

A disease in the process of its development violates the functions of all organs and systems. First, the nervous system suffers, which is manifested by a series of actions that reduce the protective function of the body and provoke blood stasis in the lungs, swelling of the mucous membranes of the bronchioles and bronchi. Since the lungs are weakened, conditions are created in them for the development of inflammatory processes. Reduced gas exchange in them leads to a decrease in gas exchange in the tissues.
How to treat
The time of treatment and its effectiveness depends on the conditions in which the "patient" is, and the quality of care for him. Place the calf in a separate box or paddock. Follow all doctor's instructions.
Did you know? The calves are very sociable. On pastures they always keep in groups. After isolation, try to come to the sick as often as possible in order to brighten up their loneliness.
Treatment should be comprehensive, including addressing the causes of the disease. Remember that the symptoms of the disease in their manifestation lead to exhaustion of the animal. To help him maintain his strength to fight the disease and avoid death, give symptomatic treatment. Start with inhalation. It is effective due to the large area of the lungs and their absorption capacity. It also enhances blood circulation.
- baking soda;
- proteolytic enzymes;
- herbal decoctions and infusions;
- oil extracts.
Antibiotics are used to treat the disease. The correct selection of drugs affects the effectiveness of the treatment course. In the acute form of bronchopneumonia, penicillin or streptomycin is prescribed. The second drug is administered intravenously with novocaine. The course of treatment is up to a week. Injection is done three times a day. Antibiotics are injected into the bronchial tree using a special nebulizer.
Did you know? Cows have a good memory; they distinguish people not only visually, but also by voice and smell.
Treatment is supplemented with antihistamines, which reduce vascular permeability. They are aimed at reducing the likelihood of an allergy to the products of the activity of the pathogen, as well as antibiotics.
- Calcium glucanate;
- Sodium thiosulfate.
During the disease, immunity is weakened, therefore it is necessary for him to help fight the disease. For this, the veterinarian prescribes special immunostimulants. Blood serum is also used, which is taken from healthy calves and poured into the patient. But there are times when treatment is ineffective.
Important! Do not try to treat yourself. Use only drugs prescribed by your veterinarian.
The best escape from illness is prevention. It consists of:
- proper nutrition;
- intensive and high-quality feeding;
- compliance of premises for animals with such requirements: relative humidity - 70%, without a sharp temperature drop; the air has an ammonia content of not more than 5 mg / m;
- regular walks;
- creating a canopy on the walking area in the heat;
- clean stalls;
- the use of disinfectants;
- the introduction of vitamins in the diet;
- regular examination by a veterinarian;
- quick response to strange behavior and appearance of the calf;
- periodical calf chest massage.
