Understanding the choice behaviours of farmers around the treatment of their livestock is critical to counteracting the risks of antimicrobial resistance (AMR) emergence. Using varying disease scenarios, we measure the differences in livestock species’ treatment preferences and the effects of context variables (such as grazing patterns, herd size, travel time to agrovet shops, previous disease experience, previous vaccination experience, education level, and income) on the farmers’ treatment choices for infections across three production systems—agro-pastoral, pastoral, and rural smallholder—in northern Tanzania, where reliance on antimicrobial treatment to support the health and productivity of livestock is high. Applying a context-dependent stated choice experiment, we surveyed 1224 respondents. Mixed logit model results show that farmers have higher preferences for professional veterinary services when treating cattle, sheep, and goats, while they prefer to self-treat poultry. Antibiotics sourced from agrovet shops are the medicine of choice, independent of the health condition to treat, whether viral, bacterial, or parasitic. Nearness to agrovet shops, informal education, borrowing and home storage of medicines, and commercial poultry rearing increase the chances of self-treatment. Based on our findings, we propose interventions such as awareness and education campaigns aimed at addressing current practices that pose AMR risks, as well as vaccination and good livestock husbandry practices, capacity building, and provision of diagnostic tools.
