[Fowl Cholera. Preventive treatment with antibiotics (author's transl)].

In view of an outbreak of fowl cholera in the duck-and turkey-farming industry, the possibility of instituting long-term preventive treatment of recently acquired birds on the farms involved was studied. Satisfactory results were obtained in Peking-ducks and turkeys when chlortetracycline was administered at a concentration of at least 100 ppm in the feed for three weeks. Satisfactory results were also obtained using a combined preparation of neomycin and oxytetracycline in muscovy ducks or a preparation of neomycin, chloramphenicol and chlortetracycline in Peking-ducks following experimental infection.
