title: A survey of group-level antibiotic prescriptions in pig production in France.
abstract: There is world-wide concern that antimicrobial use in food-producing animals might contribute to antimicrobial resistance both in animals and in humans. The relationship between antimicrobial use and resistance is likely to be related to frequency of prescription of the compound, dose and duration of treatment. Routine collection of that information is not possible today in France. A postal survey of French pig veterinarians therefore was carried out in October 2000. The questionnaire focused on the last antibiotic group-level prescription made; data were collected on the type of animals, presumptive clinical diagnosis and drug prescription. The list frame was defined using a veterinary yearbook. All practitioners with mention of pig in the treated species or with employment in intensive animal production were sent the questionnaire. Out of the 431 selected practitioners, 303 responded to the self-administered questionnaire (overall return proportion 70%). 159 prescriptions were received and analysed (response proportion 37%). Their repartitions according to indications and active compounds were summarised. Mean prescribed daily doses and mean treatment length were calculated for four antibiotics: amoxicillin, colistin, oxytetracycline, tylosin. Prescribed daily dose were in the range of dosages used and recommended in Europe. High variations were encountered in treatment length: from 3 to 21 days.
