Johne’s disease in cattle is a significant global animal health challenge. Johne’s disease is chronic, affecting the gastrointestinal tract of cattle and other ruminants and is caused by the bacteria Mycobacterium avium ssp. Paratuberculosis. Many countries have introduced schemes and programmes to try and control the spread of Johne’s disease, including the UK. Despite efforts to control it, however, Johne’s disease remains consistently ranked by UK producers as the top ranked disease negatively affecting productivity, indicating that schemes are not perceived to have solved the problem fully. Building on a global systematic review of the literature on barriers and solutions for Johne’s disease control on-farm, we conducted an empirical study with over 400 farmers and 150 veterinary professionals across the UK. The study used workshops and semi-structured interviews to understand better the challenges dairy farmers and veterinarians face in implementing on-farm Johne’s disease management schemes with the aim of identifying solutions. The study found that four main challenges are faced in the on-farm control of Johne’s – (1) Management of farmer expectations around Johne’s disease, with eradication near impossible, (2) Issues regarding space for segregation and the related economics of control (3) A ‘free-riding’ problem which can be influenced by the voluntary nature of control plans and (4) Challenges in vet-farmer communication, including levels of knowledge. Our findings have relevance for the control of Johne’s disease in the UK and other countries, including for regions with voluntary and compulsory control programmes.
