How light is too light touch: The effect of a short training-based intervention on household poultry production in Burkina Faso
基于布基纳法索1798户家庭的大规模随机试验，评估短期培训干预对家禽养殖的影响，发现对产量和利润无显著效果，仅对大型养殖户的投入和死亡率有微弱改善。
This paper reports on the effects of a training-based intervention seeking to increase household engagement in poultry production in Burkina Faso, analyzing data from a large-scale cluster randomized trial in which 1798 households in 60 communes were observed over a period of three years. The intervention SELEVER - entailing a short series of trainings for households as well as capacity building for local animal health and credit services - had little effect on household poultry production and no effect on profits. There is some evidence of an increase in the utilization of poultry inputs and an associated reduction in poultry mortality, primarily for larger poultry producers; however, there is no evidence of any treatment effects for the smallest producers.
