Compositions for the prophylactic and/or therapeutic treatment of disease, particularly in poultry, comprising tylosin, a tetracycline and an acidic agent. Optionally, the compositions further comprise 2-pyrrolidone. The combination enhances the therapeutic effect of the tertracycline. The compositions are stable upon storage in the form in which they are intended to be administered to poultry. The invention concerns also the combined use of tylosin and tertracycline for the treatment of animal disease and the conversion of tylosin A to tylosin B by 2-pyrrolidone. |
