Input: Research personnel and advisors perform data collection. Data on use is obtained from farmers records on drugs delivered (with assistance from veterinary practices and feed mills). Information is available separately for in-feed, oral and injectable antibiotics. For chickens, data is provided by veterinarians as per flock including the reason for use.
Analysis, benchmarking and reporting
AMU in pigs is processed into the weight-based indicators mg and mg/kg but is available in different units for benchmarking with other countries including DDD and DCD as outlined in ESVAC documents. Pig farmers are benchmarked but no thresholds are established. Benchmarking is based on total use and also critically important antimicrobials separately. The pig farm-level results are then discussed with the farmers. All pig farmers in the database received an individual report and a benchmarking report for their farms combined with information in production, biosecurity and slaughter house findings. Data has been further analyzed combined with operational data to identify risk factors for high use.Poultry data is only used internally for decision making.
