As a respiratory disease in dairy cows, pneumonia occurs frequently throughout the entire lifespan of the animal and can have severe consequences, making it one of the most economically significant diseases in dairy farming.
The reason lies in the anatomical structure of the cows’ lungs. In addition, lung diseases are often triggered by a wide variety of factors. Thus, viral respiratory diseases can also weaken the organism and later trigger bacterial diseases of the respiratory tract.
If the symptoms of pneumonia, such as increased temperature, nasal discharge or coughing, remain undetected or are not treated until it is too late , the disease can develop into chronic pneumonia. In this case, there is a risk of permanent lung damage, which can lead to a permanent reduction in performance and, in particularly severe cases, to the death of the animal.
In addition to stress factors such as transport or mixing of groups, the barn climate, air quality, and drafts in the barn can also affect respiratory health.
