3. Survey design and data description
3.1. Survey Design The data used for this study is based on a 2006/2007 household survey in Ethiopia that was conducted by the International Livestock Research Institute (ILRI) in Ethiopia. The study was conducted mainly to identify successful cases of improved livestock feed technologies use in the country and assess common factors, processes and organizational arrangements underpinning the successful cases. Before the household survey, desk review, reconnaissance survey, and participatory rural appraisal were used to understand forage innovation system, identify positive deviant households in the country, and design the data collection instrument. Then the survey was designed to collect information on household characteristics, resource endowment, feed technology transfer arrangements, social capital and networks, household behaviors, and other related variables that are hypothesized to influence success and use of livestock feed technologies. Purposive and stratified sampling techniques were used to select the study samples. Sampling was done based on the result of desk review and reconnaissance survey. Even though desk review and the reconnaissance survey results showed that districts with cases of positive deviance were distributed across the four regional governments, namely, the Oromia, Amhara, South Nations and Nationalities People (SNNP) and Tigray regions, using predefined stratification criteria, variability, and budget considerations, only three regions were included in the study. Following the selection of regions, a stratified three-stage cluster sampling method was adopted to select sample households. At first, sample list of districts were identified using the stratification criteria and variability. Then, sample Kebele Administrations (KAs) were purposively selected by key informants and promoters of improved feed technologies in the districts where positive deviance was identified. Finally, feed technology user households were selected randomly from each KA feed technology users master list developed by KA level key informants and administrative leaders. Totally, six hundred and three (603) households were sampled based on the proportion of positive deviant population size in each region (Kiggundu, 2007). Finally, the data was collected using pre-tested structured questionnaire by trained and experienced enumerators. After data entry and cleaning, the data was analyzed using Stata version 12 statistical package.
