VetCAb-ID (Veterinary Consumption of Antibiotics – International Documentation) is a scientific project that collects and analyses data on antimicrobial usage in animals in different countries. It is conducted by the University of Veterinary Medicine Hannover, Germany, namely by the Institute for Biometry, Epidemiology and Information Processing, designated as WHO Collaborating Centre for Research and Training for Health at the Human-Animal-Environment Interface. The aim of VetCAb-ID is to describe data on the use of antibiotics in animal populations in different countries and thus to provide a data basis for scientific assessment. The VetCAb-ID data base was launched in November 2018 with two partners from Chile. Other countries can join, eligible partners being universities, research institutes, governmental bodies or veterinary authorities.

Data collection

Animal (sub)categories: All farm animals of any age/weight category.

InputIn order to participate in the project, a partner should be able to capture data on antimicrobial use in their country. For a first trial, a data set of an animal population of choice is needed (e.g. usage data for fattening pigs in some farms during on a temporal basis). In general, the vet is the most reliable source of information; data are mainly collected and reported by vets. The farmers should agree on AMU data reporting of their herd(s). Furthermore, a list of the antibiotics used most often in the country in the respective animal population is required, containing certain information on each drug.


As in VetCAb-S, the count-based indicator ‘treatment frequency’ can be calculated. This uses a weight assumed by the veterinarian at the day of treatment, and the number of animals or number of stable places.


Benchmarking is not a priority in the VetCAb-ID project, although the system could help countries to build up a benchmarking based on the collected information.

Communication strategy

Participation in the project is possible for everyone. The project was/is introduced at different conferences, and there is a website ( First results from Chile were presented in September 2019.
