The five-year UK antimicrobial resistance (AMR) National Action Plan (NAP) was published in 2019 focusing on reducing the need for, and unintentional exposure to antimicrobials (AMs); optimising the use of AMs; and investing in innovation, supply and access of AMs. This study aimed to evaluate the progress made in the beef cattle sub-sector in addressing specific NAP commitments related to improving animal health and welfare and responsible antimicrobial use (AMU). A thematic analysis was conducted of 21 semi-structured interviews with stakeholders from government organisations, farms, veterinary practices, levy boards and livestock associations. The findings indicate substantial progress, with various initiatives implemented targeting data collection, farmer and veterinarian engagement, and herd health planning. However, there remain a number of challenges and barriers that need to be addressed in order to assess the impacts of these initiatives, such as the availability of AMU and AMR data. Ensuring the adequacy of resources was found to be critical for the sustainability of effective initiatives, considering competing demands on people's time. Additionally, the importance of other outcomes from these initiatives such as developing and strengthening the farmer-veterinarian relationship should not be underestimated since it is fundamental to successfully addressing issues such as AMR.
