Livestock provide meat, milk, draught labour, are used for breeding, and act as a store of value for smallholder farmers. High young stock mortality (YSM) has the potential to cause significant financial loss. The Young Stock Mortality Reduction Consortium collaborated on a project to deliver a package of basic health and husbandry interventions to reduce YSM for cattle and small ruminants in mixed and pastoral production systems in Ethiopia. Prior to the intervention, YSM rates ranged from 9.8% for calves in mixed systems, to 35.6% for small ruminants in pastoral systems. Proportional reductions YSM from the intervention ranged from 60% for calves and for small ruminants in mixed systems, to 72% for calves in pastoral systems. This brief research report assesses the costs and benefits of the intervention ex-poste to determine its efficiency. NPVs for the intervention (per household) were calculated for a range of benefit periods (from 1 to 20 years), based on the cost of training enumerators and farmers and the net annual household benefits realised within each benefit period. We found in both pastoral and mixed systems the net annual household benefit for the intervention was positive. For pastoral households the intervention achieves a positive NPV after 2 years. For mixed households the intervention achieves a positive NPV after 11 years. Overall, we found the benefits of the intervention exceed the costs, by a very large amount in pastoral systems, and that benefits were larger for households that kept larger numbers of breeding females.
牲畜提供肉、奶、役力,用于繁殖,并作为小农户的一种价值储存方式。高幼畜死亡率(YSM)有可能造成重大经济损失。幼畜死亡率降低联盟合作开展了一个项目,提供一系列基本健康和饲养干预措施,以降低埃塞俄比亚混合生产系统和牧区生产系统中牛和小反刍动物的幼畜死亡率。在干预之前,幼畜死亡率在混合系统中的犊牛为9.8%,在牧区系统中的小反刍动物为35.6%。干预后幼畜死亡率的比例降低幅度在混合系统中的犊牛和小反刍动物为60%,在牧区系统中的犊牛为72%。这份简短的研究报告评估了干预措施事后的成本和效益,以确定其效率。根据培训调查员和农民的成本以及每个效益期内实现的家庭年度净收益,计算了一系列效益期(从1年到20年)内干预措施的净现值(每户)。我们发现,在牧区和混合系统中,干预措施的家庭年度净收益都是正的。对于牧区家庭,干预措施在2年后实现了正的净现值。对于混合家庭,干预措施在11年后实现了正的净现值。总体而言,我们发现干预措施的效益超过成本,在牧区系统中超出幅度很大,而且对于饲养较多繁殖母畜的家庭,效益更大。
