The document reports on a study investigating antimicrobial use among smallholder livestock farmers in Ethiopia, highlighting the prevalent lack of knowledge about antibiotics and vaccination among livestock owners. It reveals concerning patterns of antimicrobial use, including reliance on human antibiotics and a significant portion of farmers using antibiotics inappropriately. Findings indicate a need for improved monitoring and targeted interventions to address antibiotic misuse and resistance in the livestock sector.

2. Introduction
• Globally continued increase in AMU in food-animal
production expected, especially in LMICs
• Irresponsible AMU and the resultant selective pressure
is a major driver for AMR
• Major food safety and public health concerns linked to
AM residues and AMR

3. Introduction
HICs
• Policies to restrict the
use of AM agents in
animals in place and
enforced
• Monitor trends in AMU
and AMR in livestock
LMICs
• Only limited, or unreliable,
data regarding AMU
(counterfeit and illegal
imports)
• Policies are not enforced
• Access to antimicrobials is
improving
•AMR has no boundaries, it is a global issue
•It does not matter where a resistant bacterium originates

4. Ethiopia
• The largest livestock population in Africa
• Different production systems and agro-ecology
• Very scarce information on antimicrobial usage in
animals
• Factors and incentives influencing AMU are poorly
understood

5. Objective
To understand knowledge and practice of smallholder
farmers regarding antimicrobial use, resistance and
residue

6. Materials and methods
• Cross-sectional survey
• 12 representative sites
were selected from six
districts, representing 3
different agro-ecologies
• 379 randomly selected
households

7. Survey tool
• Questions on: HH demographics, farm characteristics,
management of manure, feed types, animal health constraints,
disease prevention, animal health services, antimicrobial use,
farm product consumption and cost of animal health
• Open-ended and closed
questions
• Drug-box prepared
with products bought
in local vetdrug stores
• ODK on tablets for data
collection

8. Drug-box

9. Results

10. Knowledge
• 19% of livestock owners were unable to explain what
antibiotics do
• 17% of livestock owners were unable to explain what
vaccination does

24. Conclusions
• Differences across production systems
• Lack of knowledge and wrong practices were common
• Need to understand and monitor antimicrobial use in small
holder livestock keepers in Ethiopia
• Access to veterinary drugs limited in some areas (highlands)
• Increase in counterfeit and illegal imports (pastoralist areas)
• Findings of the study help to target future interventions to
reduce antimicrobial use and resistance

25. Outlook
• Further analysis planned: study behavior in more detail
to understand drivers of use
• Identify and target interventions (incentives, address
drivers of use, etc.)
• Check quality of drugs
• Link drug use with residues and AMR in meat and dairy
samples
