Respiratory diseases in veal calves

Infectious diseases of the respiratory organs (bovine respiratory disease (BRD)) is one of the most common diseases in calves worldwide, leading to enormous economic losses. Moreover, BRD is the most important indication for the use of antibiotics in calves. In a first series of studies in the veal calves sector, Mycoplasma bovis and the bovine viral diarrhea virus were identified as the most common pathogens. For practical and financial reasons antibiotic treatment for BRD is mostly immediately deployed without prior sampling. In view of a responsible use of antibiotics, it is preferable to have disposition of diagnostical techniques, validated to account for medication on the group level. These group diagnostics are, together with the identification of risk factors for BRD,  especially in veal calves, the subject of further research in our department.
