Exposition des veaux de boucherie aux antibiotiques

Abstract : Abstract Exposure of veal calves to antibiotics France is a major producer of white veal calves in Europe, but few data are available on the exposure of these animals to antimicrobials. A cross-sectional study was conducted in 2013-2014 on 186 French veal calf batches (93 farms) to estimate the exposure of white veal calves to antimicrobials. An indicator, the number of antibiotic treatments per calf, was calculated based on veterinary prescriptions (products, quantity dispensed and dosage prescribed) and estimated weight of calves at treatment. The calves were heavily exposed to antibiotics, with an average of 8.6 antibiotic treatments per calf over the entire fattening period. Among the antimicrobial classes used, tetracyclines were predominant (4.3 treatments per calf on average), but polypeptides (colistin), macrolides and sulfonamides were also prevalent (1.6, 1.0 and 0.6 treatments per calf, respectively). " Starting treatments " were invariably administered to calves at their arrival and represented about one third of the total number of treatments. The study showed low variability of exposure between farms, indicating that efforts to reduce the use of antimicrobials should be implemented at the sector scale rather than the farm scale.
