WE would like to alert colleagues that there has been a faulty version of the Nottingham Sheep antimicrobial usage (AMU) calculator available online and we would urge all colleagues to check which version they are using and to redownload the most up-to-date version (version 3.5).

In support of current veterinary, agricultural and One Health cross-industry and cross-sector initiatives, we strongly encourage all colleagues and farm clients to record their antibiotic usage data. In recent years, this has been aided by the freely available Sheep AMU calculator that was originally developed by vets at the University of Nottingham and funded by the AHDB. The calculator allows farmers and practitioners to input the quantities of antibiotic used on farm together with the numbers of ewes and lambs, and enables a simple upload to the electronic medicine hub, which is important to demonstrate national use across the UK.

The most up-to-date version of the calculator is labelled ‘version 3.5’ and can be accessed from https://bit.ly/3KB6Rhg or https://bit.ly/3IpLop0
