Acknowledgements

We thank the Director of Kenya Trypanosomiasis Research Institute for allowing the data collected during the survey to be used in this Case Study, and also for permission to include for reference purposes the full report by Irungu (2000). The original study could not have been done without the support of the local District Veterinary Office in Tana River, the willingness of the Orma pastoralists to participate in the survey and the cattle that they owned.
