Summary
# Editorial Summary: Pain Recognition in Working Donkeys Through Behavioural Response to Analgesia Recognising pain in working donkeys presents a significant challenge for veterinarians and owners in field settings, yet effective pain management depends on accurate identification. This observer-blinded, placebo-controlled trial administered meloxicam (1.2 mg/kg orally) or placebo to 40 adult male working donkeys with common clinical abnormalities, then systematically observed postural and event behaviours at baseline and four post-treatment timepoints using standardised scan and focal sampling methods. Donkeys treated with meloxicam demonstrated substantially altered behaviour compared to placebo: they lay down less frequently (P = 0.007), kept their eyes closed less often (P = 0.04), carried their heads higher (P = 0.02), showed reduced dozing (P = 0.03), and responded more readily to environmental stimuli (P = 0.05), indicating increased alertness and engagement. Whilst lameness scores did not improve significantly in either group, these robust behavioural changes confirm that analgesia-responsive indicators—particularly postural shifts and attentiveness—can reliably signal the presence of pain in working donkeys. For practitioners managing donkeys in resource-limited settings, monitoring specific behaviours such as head carriage, recumbency patterns, and environmental awareness offers a practical, low-cost means of identifying pain-related welfare compromise and evaluating treatment efficacy without relying solely on lameness assessment.

Practical Takeaways
- •Behavioural changes (increased alertness, reduced lying down, higher head carriage) are reliable indicators of pain relief in working donkeys and can help you assess analgesic effectiveness in field conditions
- •NSAIDs like meloxicam may improve donkey welfare by reducing pain-related behaviours, even when lameness scores don't change—observe posture and activity levels rather than relying solely on gait assessment
- •Training owners and veterinary staff to recognise these behavioural pain indicators enables earlier intervention and better monitoring of treatment response in working donkey populations
Key Findings
- •Donkeys receiving meloxicam were more alert post-treatment, lying down less frequently (P=0.007) and with eyes closed less frequently (P=0.04) compared to placebo
- •Meloxicam-treated donkeys showed higher head carriage (P=0.02) and decreased dozing behaviour (P=0.03) compared to baseline
- •Meloxicam group demonstrated increased environmental interest with more frequent orientation to stimuli (P=0.05) than placebo group
- •Neither treatment group showed significant post-treatment improvement in lameness scores
