Aim of the study is to evaluate how often livestock animals are treated with antibiotics during a defined time period, using the treatment frequency (TF) i.e. # treated animals x # treatment days / # animals per farm. Furthermore, it is investigated, if regions or farm sizes differ regarding antibiotic usage or which substances are used most frequently.
- Pigs: sows, finishers, weaners and sucklers;
- Poultry: broilers;
- Cattle: dairy cows, beef cattle and fattening calves
Input: Participating veterinarians and farmers voluntarily provide information about consumption of antibiotics on farm level by official application and delivery forms, which are transferred into a database. For the latter, the number of treated animals, number of treatment days, name and amount of the antimicrobial product used, the route of application and the indication are collected. In 2021 more than 300,000 records for pigs, cattle and poultry of the years 2011 to 2020 were included into the database.
