Measures taken by Veterinarians in Sweden in Cases of Bovine Mastitis

A questionnaire concerning the diagnosis and treatment of bovine mastitis was sent to all 350 Swedish food animal practitioners. 287 (82%) of the questionnaires were returned. One of the main aims was to establish if Swedish food animal practitioners used a common therapeutic regime that could be used as a control treatment in future clinical trials. It was found that many factors of importance for the clinical diagnosis of mastitis such as body temperature, duration of the symptoms etc. often were not considered. On the other hand 60–70% of the practitioners regularly took milk samples to obtain a bacteriological diagnosis. Approximately 40% of the veterinarians cultured the milk samples in their home laboratory. Basic measures like frequent emptying of the udder were recommended by only 40–50% of the veterinarians. All responding field veterinarians used the systemic route for administering antibiotics when treating cases of acute, clinical bovine mastitis. The drug of choice, initially, in these cases was benzylpenicillinprocain, which was used by 65–75% of the veterinarians. Twentyfive percent used a broadspectrum antibiotic, most commonly a combination of penicillin and streptomycin. A minority (5%) directed their initial therapy towards gramnegative bacteria. About 30–40% supported the systemic therapy with intra-mammaries. Other drugs such as NSAID, corticosteroids and oxytocin was used, on a regular basis, by only about 10% of the practitioners.
