Institute of Epidemiology (IfE)

Antibiotic minimization in broiler farming through hygiene measures and optimization of biosecurity, animal health and management (short: MiniAB#Broiler)


Duration: 01.09.2023 – 31.12.2025

Funding: Federal Ministry of Food and Agriculture (BMEL) on the basis of a resolution of the German Bundestag, project sponsor is the Federal Office for Agriculture and Food (BLE), (funding reference 2820MDT230)

The Institute of Epidemiology of the Friedrich-Loeffler-Institute evaluates in a work package the biosecurity standards based on the principles of a risk assessment approach aiming at the possibility of improving the existing systems. The project is part of the Model and Demonstration Projects (MuD) Animal Welfare in the Federal Livestock Farming Program.

Work packages:

  • Biosecurity of the farm and hygiene management (FLI & UROS)
  • Cleaning and disinfection (UROS)
  • Animal health and barn and herd management (TiHo and LMU)
  • Knowledge transfer (UROS)


As part of work package 1, the biosecurity of broiler farms is assessed using the AI risk traffic light of the University of Vechta (https://risikoampel.uni-vechta.de/ ). Farm management factors that have a potential influence on animal health and the resulting use of antibiotics are evaluated and assessed.

Research objective:

The project "Antibiotic minimization in broiler farming through hygiene measures and optimization of biosecurity, animal health and management" (short: MiniAB#Broiler) has the overarching goal that farms with a high antibiotic use (ABU) can learn from farms with a comparably low ABU and identify and optimize parameters to improve animal health. The individual objectives of the project are to improve the biosecurity of broiler farms, improve the overall hygiene of broiler farms, improve the animal health of broiler chickens, minimize the use of antibiotics, transfer knowledge between broiler farms with low and high antibiotic use and optimize risk areas based on knowledge transfer.
