This paper reports on livestock mortality in Afghanistan where a war has been going on for more than a decade, with complete disruption of the veterinary field services. The study attempted to measure the impact of a veterinary field programme carried out mainly by paravets. The study also provides valuable data on the impact of diseases in the absence of any veterinary intervention. The veterinary programme, implemented by a Dutch non-governmental organisation (NGO) for approximately 3 years, consisted essentially of vaccination against major infectious diseases and administration of anthelmintic drugs for nematodes and liver flukes. Veterinary personnel were also involved in curative treatments. Livestock mortality figures were collected by questionnaire over a period of 2 years from more than 700 farmers in randomly selected villages in 4 covered districts with a veterinary programme and 4 control districts without a veterinary programme. The average annual mortality rates for calves, lambs and kids respectively were 16.2%, 17.3% and 19.1% in the covered areas, against 21.5%, 25.2% and 24.6% in the control areas. Adult mortality figures were 3.8%, 7.4% and 5.4% in the covered areas, against 5.3%, 13.6% and 15.6% in the control areas for cattle, sheep and goats respectively. The survey indicated significant differences (P < 0.01 in cattle, P < 0.001 in small ruminants) in livestock mortality between the control and covered areas and it is concluded that these differences were attributable to the presence or absence of the animal health programme.
本文报道了阿富汗的牲畜死亡率情况,该国已历经十多年战乱,兽医现场服务完全中断。该研究试图衡量主要由兽医助理开展的一项兽医现场项目的影响。该研究还提供了在没有任何兽医干预情况下疾病影响的宝贵数据。由一个荷兰非政府组织实施约3年的兽医项目,主要包括针对主要传染病的疫苗接种以及对线虫和肝吸虫施用驱虫药。兽医人员也参与治疗。通过问卷调查,在两年时间里从4个设有兽医项目的覆盖区和4个没有兽医项目的对照区中随机选取的村庄里的700多名农民那里收集了牲畜死亡率数据。在覆盖区,犊牛、羔羊和幼崽的年平均死亡率分别为16.2%、17.3%和19.1%,而在对照区分别为21.5%、25.2%和24.6%。在覆盖区,成年牛、羊和山羊的死亡率分别为3.8%、7.4%和5.4%,而在对照区分别为5.3%、13.6%和15.6%。调查表明,对照区和覆盖区之间牲畜死亡率存在显著差异(牛的P<0.01,小型反刍动物的P<0.001),并得出结论,这些差异归因于动物健康项目的有无。
