Input: Data are collected from production organisations. They transmit production data (e.g. flocks size, weight slaughtered) and antimicrobial usage data, entered in their own databases either by veterinarians (prescriptions or deliveries) or farmers, twice a year. ANVOL anonymises and aggregates the data before sending to ITAVI.
Two ways for quantification are considered: based on treatments administration or on packages delivered.
Unit of measurement: AMU is expressed as a number of DDD or DCD making use of national DDD and DCD values (made publicly available by the French Agency for Veterinary Medicinal Products (ANMV)).Indicators: number of DDD and DCD are reported to the amount of kilograms slaughtered.
