| Abstract: | In 1979, 209 cows from 2742 patients in the clinic for obstetrics and gynecology suffered from coliform mastitis. Most of these animals had been sent to the clinic because of a general or local infectious disease, a delayed birth or a teat injury. Coliform mastitis developed secondarily. Only 12 animals (6%) had solely a mastitis and no other clinically recognisable disease. Most of them showed a secondary acetonemia (ketosis). The connection between hypoglycemia, disturbance of the body's own defense mechanism and development of a coliform mastitis is discussed. The frequent occurrence of coliform mastitis in dairy herds with sawdust bedding is not directly attributed to a coliform contamination of the bedding but indirectly to a lack of crude fibre content in the diet which results in a subclinical ketosis and a dysfunction of the leucocytic defense. Coliform mastitis predominantly is not a hygienic but a management problem. |
