摘要

牲畜健康状况不佳给全球南部的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,这些服务往往无法惠及农民。在此,我们研究了如何通过提供东海岸热(ECF)疫苗--一种影响非洲牛群的蜱媒疾病--来减少典型的采用障碍。利用肯尼亚奶农的选择实验数据,我们评估了奶农对疫苗提供方面各种制度创新的偏好和支付意愿,如加强奶牛合作社的作用、采用核销系统的新支付模式、在奶农家中接种疫苗以及将疫苗接种与牲畜保险折扣捆绑等。我们的数据显示,农民对 ECF 疫苗的认识有限,采用率较低,这主要是由于制度上的限制。混合对数模型和潜类模型的结果表明,根据农民的不同情况进行适当的制度创新,可以显著提高采用率。这一普遍结论可能也适用于全球南部地区的其他兽医技术和服务。

Farmer-friendly delivery of veterinary services: Experimental insights from the Kenyan dairy sector

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.
