The traditional livestock sector in Somalia is based on nomadic pastoralism where sheep, goats and camels are herded in large numbers. Data from 1609 females (27 % lactating) and 550 males (26 % exported) belonging to 40 pastoralists were analysed in this study. The expected amount of revenue the herders could lose per year in the studied area was estimated at US$404,630 being made up of US$314,630 from decreased milk yield and US$90,000 from reduced market value of exported animals. However, all the camels in Somaliland are at risk of acquiring surra infection, and therefore extrapolating the current findings to the total population could potentially lose US$223,164,000. This highlights the loss in the magnitude of US$164,253,600 from decreased milk yield and US$58,910,400 from body condition loss. Overall, the benefit in controlling Trypanosoma evansi infection in the study area was US$398,880 (n = 2159). On average, US$720 was saved per head per year from improved milk production in treated animals and US$615 from the increased value of exported camels. It is concluded that all three-treatment options evaluated were economically beneficial strategies; however, the biannual treatment of seropositive camels in the herds was the best financial option.
索马里的传统畜牧业以游牧放牧为基础，大量饲养绵羊、山羊和骆驼。本研究分析了来自40个牧民的1609头雌性牲畜（27%处于哺乳期）和550头雄性牲畜（26%用于出口）的数据。据估计，在研究区域，牧民每年可能损失的收入为404,630美元，其中314,630美元来自产奶量下降，90,000美元来自出口牲畜市场价值降低。然而，索马里兰的所有骆驼都有感染苏拉病的风险，因此将目前的研究结果推算至全部骆驼数量，可能会损失223,164,000美元。这凸显了产奶量下降造成的164,253,600美元损失以及身体状况下降造成的58,910,400美元损失。总体而言，在研究区域控制伊氏锥虫感染的收益为398,880美元（n = 2159）。平均而言，每头接受治疗的牲畜每年因产奶量提高节省720美元，因出口骆驼价值增加节省615美元。研究得出结论，所评估的三种治疗方案都是经济有效的策略；然而，对畜群中的血清阳性骆驼进行半年一次的治疗是最佳的财务选择。
