1994年和1997年对布基纳法索南部耶鲁农牧区（ZAP）的所有家庭进行了访谈，以评估1994年实施的舌蝇控制方案的影响，该方案使用溴氰菊酯浸渍目标和1%溴氰菊酯对所有牛进行浇泼处理。在缺乏健康和生产力监测的情况下，通过单次访问调查收集数据，以便对牛的相关生殖能力变量进行定量估计，并评估所用投入和产出的变化。结果表明，牛群规模增加了25%，每户牛的数量从0.1头增加到1.1头;死亡率从63.1%降低到7.1%，流产率和死胎率分别降低了55.9%和51.3%;在旱季，活产率提高了57.6%，产奶量从每天每头奶牛0.2升提高到2.2升。这些结果显示了锥虫病控制对暴露于高采采蝇挑战的瘤牛的显著影响。精心设计的调查可以是一种具有成本效益的方法，以获得生产力影响的估计，可用于模拟畜群模型中畜群增长和肉奶产量的预测。虽然有许多与农民对生产力提高的看法有关的混淆因素，但这些估计数在模拟采采蝇和锥虫病控制的经济效益方面形成了主观评估的有用替代办法。
Interviews with all the households in the Agropastoral Zone (ZAP) of Yale, southern Burkina Faso, were conducted in 1994 and again in 1997 to assess the impacts of a tsetse control programme implemented from 1994, using insecticide-impregnated targets and pour-on treatments of all cattle with deltamethrin 1%. In the absence of health and productivity monitoring, data were collected in single-visit surveys in order to generate quantitative estimates of relevant reproductive performance variables for cattle and to assess changes in the inputs used and outputs produced. The results indicate a 25% increase in herd size and an increase in the number of oxen from 0.1 to 1.1 per household; a reduction in mortality from 63.1% to 7.1% and reductions in the rates of abortions and stillbirth of 55.9% and 51.3%, respectively; and an increase in the rate of live births of 57.6% and in the milk yield from 0.2 to 2.2 litres/cow per day in the dry season. These results show the dramatic impacts that trypanosomosis control can have on Zebu cattle exposed to high tsetse challenge. Well-designed surveys can be a cost-effective way to obtain estimates of productivity impacts that can be used to simulate projections of herd growth and meat and milk production in herd models. While there are many confounding factors associated with farmers' perception of a gain in productivity, these estimates form a useful alternative to subjective assessments in modelling the economic benefits of tsetse and trypanosomosis control.
