title: [Clinical and pharmacological studies of technical tylosin phosphate from Pharmachem in poultry diseases].
abstract: Investigations on the healing anbd prophylactic effectiveness of the technical tylosine phosphate "Pharmachim" with 50 IU/mg activity (pharmazin T-50) in some bird diseases were carried out. It was established that a dose of 20 g/kg fodder pharmazin T-50 applied 2 days pre- and 3 days post chicken Mycoplasma gallisepticum infection protects the chickens completely from respiratory mycoplasmosis. In order to attain a sure healing and prophylactic effect in hen spirohetosis control 10 g/kg fodder applied 2 days or on the 24th to 48th day after Borrelia anserina invasion are completely sufficient. It must be noted, moreover, that pharmazin T-50 application has not a negative effect on the build up of post-vaccinal immunity following the same illness. The good results obtained by pharmazin T-50 allow it to replace successfully the remaining medicinal preparations (some of which much more expensive) applied in the control of spirohetosis and respiratory mycoplasmosis of birds.
