Role of Topical Anaesthesia in Pain Management of Farm Animals, a Changing Paradigm.

Summary
# Editorial Summary Topical anaesthetic formulations (TAF) represent a significant shift in accessible pain management for livestock, with over 120 million lambs in Australia now receiving relief during routine husbandry procedures through farmer-applied spray products. Windsor's 2022 review synthesises field evidence demonstrating efficacy across multiple applications: surgical procedures including castration, tail docking and dehorning; therapeutic debridement of hoof lesions in lame cattle; and notably, treatment of Foot-and-Mouth Disease lesions and secondary decubital ulcers. When combined with systemic NSAIDs—particularly meloxicam administered by injection or orally—multimodal analgesia substantially reduces pain and suffering whilst promoting tissue healing, lowering viral loads in concurrent infections such as Orf, and decreasing reliance on prophylactic antibiotics. These outcomes have important implications for antimicrobial resistance stewardship, whilst the user-friendly delivery mechanism addresses a practical barrier to pain relief adoption in farm settings. For equine professionals, this paradigm shift in accessible analgesia for livestock highlights the broader potential of combining topical and systemic agents and reinforces the evidence base for prioritising pain management across species during procedures that have historically been performed without adequate relief.

Practical Takeaways
- •Not applicable to equine practice—this review focuses exclusively on livestock (sheep, cattle, pigs) pain management strategies.
- •The paradigm shift toward accessible, farmer-applied topical anaesthetics may inform future development of on-farm pain management tools in other species.
- •The evidence supports multimodal analgesia (topical + systemic NSAID) as superior to single-agent approaches for acute pain during routine husbandry procedures.
Key Findings
- •Over 120 million lambs in Australia have received topical anaesthetic formulation (Tri-Solfen®) for pain management during husbandry procedures.
- •Topical anaesthetic formulation combined with NSAIDs (meloxicam) demonstrated efficacy across multiple livestock species and surgical procedures including castration, dehorning, tail docking, and FMD lesion treatment.
- •Multimodal pain management with TAF and NSAIDs reduced viral loads in Orf infections and reduced necessity for antibiotic cover, supporting antimicrobial resistance stewardship.
- •Topical anaesthetic formulation enhanced healing of FMD lesions and reduced pain and suffering in livestock undergoing husbandry interventions.
