This study classified working donkey systems in Ethiopia into three groups: Domestic-Pastoral, Domestic-Agricultural, and Commercial. This classification aids in understanding donkey needs and improving welfare interventions.
Area of Science:
- Animal Science
- Agricultural Economics
- One Health
Background:
- Working donkeys are vital for livelihoods in low- and middle-income countries, yet lack systematic population classifications.
- Existing classifications for production animals like cattle do not apply to working donkeys.
- Understanding donkey systems is crucial for targeted interventions and improved welfare.
Purpose of the Study:
- To classify and characterize donkey systems in Ethiopia.
- To identify distinct groups of donkey ownership based on various factors.
- To provide a framework for analyzing donkey health and welfare data.
Main Methods:
- Utilized household-level questionnaire data from 241 donkey-owning households in Ethiopia.
- Employed multiple factor and hierarchical cluster analysis.
- Included data on donkey ownership, husbandry, use, and local environment.
Main Results:
- Identified three distinct donkey ownership clusters: 'Domestic-Pastoral', 'Domestic-Agricultural', and 'Commercial'.
- Differences between systems were influenced by donkey purpose, agro-ecological factors, and husbandry.
- Identified specific constraints for each cluster: welfare concerns (Commercial), drought/feed shortage (Pastoral), and infectious diseases (Domestic-Agricultural).
Conclusions:
- The new classification provides a framework for context-specific needs assessments for working donkeys.
- Facilitates the design of targeted interventions to improve equid health and household livelihoods.
- Highlights the varied challenges faced by donkeys across different systems, informing tailored support.
