A study was conducted in southwest Ethiopia to assess farmers’ perceptions of the public and private benefits of the pour-on and identify the household-level factors affecting its demand. Ninety-seven percent of the 166 survey respondents had received pour-on treatments when they were free and 67% paid for treatments the month before the survey. Farmers noted public and private benefits from using the pour-on, the most important of which were less trypanosomiasis, fewer problems with biting flies (including tsetse), and fewer problems with ticks. The probit model estimated to quantify the effects of different variables indicates that proportions of cows and oxen, distance to the treatment centre, and seasonal factors were significant determinants of demand. @words: Trypanosomiasis; Tsetse (Glossina spp.); Ethiopia; Economics; Policy 1. Introduction Africa’s livestock sub-sector is constrained by several animal health problems. Until the early- lB8Os, most of the inputs used to counter those problems were delivered by govern- ment agencies at highly subsidized rates. Tight government finances have since caused * Corresponding author at: International Livestock Research Institute, PO Box 30709, Nairobi, Kenya. ’ Present address: International Livestock Research Institute, P.O.
