Poor health conditions of livestock cause sizeable losses for many farmers in the Global South. Veterinary services, including vaccinations, could help but often fail to reach farmers under typical smallholder conditions. Here, we examine how the provision of a vaccine against East Coast Fever (ECF)—a tick‐borne disease affecting cattle in Africa—can be designed to reduce typical adoption barriers. Using data from a choice experiment with dairy farmers in Kenya, we evaluate farmers' preferences and willingness to pay for various institutional innovations in vaccine delivery, such as a stronger role of dairy cooperatives, new payment modalities with a check‐off system, vaccination at farmers' homestead, and bundling vaccinations with discounts for livestock insurance. Our data reveal that farmers' awareness of the ECF vaccine is limited and adoption rates are low, largely due to institutional constraints. Results from mixed logit and latent class models suggest that suitable institutional innovations—tailored to farmers' heterogeneous conditions—could significantly increase adoption. This general finding likely also holds for other veterinary technologies and services in the Global South.

为农民提供友好的兽医服务：肯尼亚乳制品行业的实验见解

牲畜健康状况不佳给南半球许多农民造成了巨大损失。包括疫苗接种在内的兽医服务可以提供帮助，但在典型的小农条件下往往无法惠及农民。在这里，我们研究了如何设计针对东海岸热（ECF）（一种影响非洲牛的蜱传疾病）的疫苗来减少典型的采用障碍。使用来自肯尼亚奶农的选择实验的数据，我们评估了农民对疫苗交付方面各种制度创新的偏好和支付意愿，例如奶牛合作社的更强大作用、带有核对系统的新支付方式、疫苗接种农民宅基地疫苗接种与牲畜保险折扣捆绑销售。我们的数据显示，农民对 ECF 疫苗的认识有限，采用率较低，这很大程度上是由于制度限制。混合 Logit 和潜在类别模型的结果表明，适合农民异质条件的制度创新可以显着提高采用率。这一普遍发现可能也适用于南半球的其他兽医技术和服务。
