ABSTRACT

 

Anthelmintic resistance is emerging as a serious challenge to sheep and goats rearing in many regions of the world. A study to investigate the on-farm risk factors to anthelmintic resistance in sheep and goat farms in coastal Kenya was carried out in Kilifi and Kwale counties. A total of 141 sheep and goat farmers was randomly selected and sub-locations participated in the questionnaire survey. The farm management practices relevant to helminth control were investigated and those associated with selection for anthelmintic resistance identified.The results showed that the commonly used classes of anthelmintic were levamisoles and benzimdazoles with only a very small minority making use of avermectins. The prevalent risk factors identified from this study included under-dosing, dry season treatments, lack of quarantine drenching of newly purchased animals, and use of clean pasture grazing after treatment. A more focused approach is recommended for dissemination of appropriate helminth control practices that can help slow the development of drug resistance as well as further research to understand the relationship between these factors and the rate of resistance development in other production systems.
