[The use of feed medications in swine and poultry facilities in the Weser-Ems region].

The use of medicated feed notably in large pig and poultry holdings is a major aspect of veterinary treatment against infectious diseases. Every single production of a medicated feed requires a specified written authorization by the veterinary practitioner and a carbon copy of this document must be sent to the responsible veterinary public health office. These documents-in the Weser-Ems region up to ca. 30,000 per annum-were entered into a computer database and analysed. The results are presented as diagrams and graphs. Information on the quantities of the various administered drug constituents is also included. With regard to current risks concerning residues and resistances the data gives qualified information on the per os treatment with antibiotics of food producing animals.
