A retrospective investigation of financial losses incurred by large ruminant smallholder farmers due to outbreaks of foot and mouth disease (FMD) in 2010-12 in northern Laos was conducted in 2012. The aim was to support recommendations on sustainable transboundary animal disease control strategies in the Greater Mekong Subregion (GMS). Large ruminant smallholders in the three northern provinces of Luang Prabang (LPB), Xiengkhoung (XK) and Xayyabouli (XYL) were interviewed (n = 310). Financial losses were determined, including direct losses due to mortality (100% of pre-FMD sale value) and morbidity (difference between the expected sale price pre-FMD and 1 month following onset of FMD), and indirect losses due to costs of treatments. The losses due to FMD per household varied between provinces (P < 0.001) and were USD 1124, USD 862 and USD 381 in LPB, XK and XYL, respectively, being 60, 40 and 16% of annual household income. Comparison of the costs of FMD with annual household income from sales of large ruminants indicated losses of 213, 181 and 60% of the income in LPB, XK and XYL, respectively. The variation in losses between provinces was due to differences in levels of morbidity with highest in LPB, treatment methods with antibiotic use common in LPB, age of animals sold and sale prices with higher prices in XK. Partial budget analysis of biannual FMD vaccination indicated an average net benefit of USD 22 and USD 33 for cattle and buffalo, respectively. However, vaccination alone is unlikely to control FMD in the region. Promotion of multiple large ruminant health and production intervention programmes to stimulate interest in biosecurity in addition to vaccination is recommended, providing a more sustainable pathway for poverty reduction through the current expansion of livestock investments in the GMS.
2012年对老挝北部2010 - 2012年期间口蹄疫(FMD)疫情给大型反刍动物小农户造成的经济损失进行了回顾性调查。目的是为大湄公河次区域(GMS)可持续跨境动物疾病控制策略的建议提供支持。对琅南塔省(LPB)、丰沙里省(XK)和沙耶武里省(XYL)这三个北部省份的大型反刍动物小农户进行了访谈(n = 310)。确定了经济损失,包括因死亡造成的直接损失(口蹄疫发病前销售价值的100%)和发病造成的损失(口蹄疫发病前预期销售价格与发病后1个月销售价格的差值),以及治疗费用造成的间接损失。口蹄疫给每户造成的损失在不同省份之间存在差异(P < 0.001),在琅南塔省、丰沙里省和沙耶武里省分别为1124美元、862美元和381美元,分别占家庭年收入的60%、40%和16%。将口蹄疫造成的损失与大型反刍动物销售的家庭年收入进行比较,结果表明在琅南塔省、丰沙里省和沙耶武里省分别损失了收入的213%、181%和60%。省份之间损失的差异是由于发病率水平不同(琅南塔省最高)、治疗方法不同(琅南塔省常用抗生素)、出售动物的年龄以及销售价格不同(丰沙里省价格较高)。对两年期口蹄疫疫苗接种的部分预算分析表明,牛和水牛的平均净收益分别为22美元和33美元。然而,仅靠疫苗接种不太可能控制该地区的口蹄疫。建议推广多个大型反刍动物健康和生产干预计划,以激发除疫苗接种外对生物安全的兴趣,通过目前大湄公河次区域畜牧业投资的扩大,为减贫提供更可持续的途径。
