肯尼亚纳罗克南区约三分之二的农民愿意付费，而三分之一的农民需要补偿才能接受首选疫苗和疫苗接种。首选疫苗和疫苗接种的WTP很高，但由于存在高度不确定性，需要进一步的WTP研究。愿意支付首选疫苗和疫苗接种属性和整个配置文件的影响，各种农民的人口统计和家庭特征。使用所有调查的方案，接种CBPP疫苗在经济上是值得的。牛传染性胸膜肺炎（CBPP）是一种经济上重要的跨界牛疾病，影响粮食安全和生计。对肯尼亚纳罗克南区的190户家庭进行了联合分析-条件估值，以衡量CBPP疫苗和疫苗接种的支付意愿（WTP）和需求以及影响WTP的因素。平均支付意愿的计算结果是，使用具有农民偏好特征的疫苗（首选疫苗和接种）进行接种的支付意愿为212.48肯尼亚先令（3.03美元），目前使用的疫苗和接种的支付意愿为-71.45肯尼亚先令（-1.02美元）。对于首选疫苗和当前疫苗接种，愿意支付大于零金额的农民比例分别为66.7%和34.4%。大约三分之一（33.3%）的农民需要获得平均每头牛1162.62肯尼亚先令（13.68美元）的补偿，以允许他们的牛使用首选的疫苗和疫苗接种接种CBPP疫苗。大约三分之二（65.6%）的农民需要获得平均每头牛853.72肯尼亚先令（12.20美元）的补偿，以便他们的牛使用目前的疫苗和疫苗接种接种CBPP疫苗。优先疫苗和接种的赔偿总额为6 139万肯尼亚先令（88万美元），现有疫苗和接种的赔偿总额为9 015万肯尼亚先令（129万美元）。从个人的支付意愿绘制的需求曲线表明，只有59%和27%的牛业主的支付意愿大于零愿意支付基准成本KSh 34.60的首选和当前的疫苗分别。对家庭经济状况的态度（p = 0.0078）、畜群中是否存在杂交品种（p < 0.0001）和畜群中自CBPP以来的年数（p = 0.0375）对WTP产生负面影响。它受到教育（p = 0.0251）和治疗CBPP的实践（p = 0.0432）的积极影响。CBPP疫苗接种的效益成本比（BCR）为2.9-6.1，取决于疫苗接种计划。总之，虽然有一部分农民愿意支付，但参与水平可能低于中断CBPP传播所需的水平。具有对支付意愿产生负面影响的特征的家庭需要说服参与CBPP疫苗接种。接种CBPP疫苗在经济上是值得的。使用总支付意愿作为收益的收益成本分析（BCA）可以用作传统BCA的替代方法，传统BCA使用避免的生产损失（新收入）和节省的成本作为收益。
About two-thirds of farmers in Narok South District of Kenya were willing to pay while one-third needed compensation to accept the preferred vaccine and vaccination. The WTP for preferred vaccine and vaccination was high but since there was high level of uncertainty, further WTP studies are needed. Willingness to pay for preferred vaccine and vaccination attributes and for the entire profiles was influenced by various farmer demographics and household characteristics. Vaccination against CBPP was economically worthwhile using all programmes investigated. Contagious bovine pleuropneumonia (CBPP) is an economically important trans-boundary cattle disease which affects food security and livelihoods. A conjoint analysis–contingent valuation was carried out on 190 households in Narok South District of Kenya to measure willingness to pay (WTP) and demand for CBPP vaccine and vaccination as well as factors affecting WTP. The mean WTP was calculated at Kenya Shillings (KSh) 212.48 (USD 3.03) for vaccination using a vaccine with the characteristics that were preferred by the farmers (preferred vaccine and vaccination) and KSh −71.45 (USD −1.02) for the currently used vaccine and vaccination. The proportion of farmers willing to pay an amount greater than zero was 66.7% and 34.4% for the preferred and current vaccine and vaccination respectively. About one third (33.3%) of farmers would need to be compensated an average amount of KSh 1162.62 (USD 13.68) per animal to allow their cattle to be vaccinated against CBPP using the preferred vaccine and vaccination. About two-thirds (65.6%) of farmers would need to be compensated an average amount of KSh 853.72 (USD 12.20) per animal to allow their cattle to be vaccinated against CBPP using the current vaccine and vaccination. The total amount of compensation would be KSh 61.39 million (USD 0.88 million) for the preferred vaccine and vaccination and KSh 90.15 million (USD 1.29 million) for the current vaccine and vaccination. Demand curves drawn from individual WTP demonstrated that only 59% and 27% of cattle owners with a WTP greater than zero were willing to pay a benchmark cost of KSh 34.60 for the preferred and current vaccine respectively. WTP was negatively influenced by the attitude about household economic situation (p = 0.0078), presence of cross breeds in the herd (p < 0.0001) and years since CBPP had been experienced in the herd (p = 0.0375). It was positively influenced by education (p = 0.0251) and the practice of treating against CBPP (p = 0.0432). The benefit cost ratio (BCR) for CBPP vaccination was 2.9–6.1 depending on the vaccination programme. In conclusion, although a proportion of farmers was willing to pay, participation levels may be lower than those required to interrupt transmission of CBPP. Households with characteristics that influence WTP negatively need persuasion to participate in CBPP vaccination. It is economically worthwhile to vaccinate against CBPP. A benefit cost analysis (BCA) using aggregated WTP as benefits can be used as an alternative method to the traditional BCA which uses avoided production losses (new revenue) and costs saved as benefits.
