We examined several procedures for surgical tail docking; with and without general anaesthesia (GA), including the use of a topical wound gel formulation to provide pain relief (PR) and improve healing after surgery, containing local anaesthetics lignocaine and bupivacaine, with cetrimide and adrenalin. Forty-four lambs were recruited into four equal cohorts: Groups A and C, the tail was excised with a scalpel without anaesthesia or stitches; Groups B and D, the tail was surgically excised and stitched under GA; Groups C and D wounds were immediately sprayed with PR. Behavioural observations identified that Groups A and C displayed significantly less pain-related behaviours than Groups B and D shortly after the procedure, especially if treated with PR. Similarly, the mean of days when animals showed no signs of wound infection was longer in the groups not undergoing stitching. Finally, treatment with PR appeared to reduce the cortisol response and avoided the elevation of serum amyloid A in lambs where the tail was excised without general anaesthesia. In conclusion, surgical tail-docking without GA but where wounds are immediately sprayed with PR, appears as an affordable and more welfare-appropriate method for conducting tail docking in lambs.
我们研究了几种手术断尾方法；包括有无全身麻醉（GA），其中使用一种局部伤口凝胶制剂来缓解疼痛（PR）并促进术后愈合，该制剂含有局部麻醉剂利多卡因和布比卡因以及西曲溴铵和肾上腺素。44只羔羊被分为四个相等的队列：A组和C组，用手术刀在无麻醉或缝线的情况下切除尾巴；B组和D组，在全身麻醉下手术切除尾巴并缝合；C组和D组的伤口立即喷洒PR。行为观察发现，在手术后不久，A组和C组表现出的疼痛相关行为明显少于B组和D组，尤其是在接受PR治疗的情况下。同样，未进行缝合的组中动物无伤口感染迹象的平均天数更长。最后，在未进行全身麻醉而切除尾巴的羔羊中，PR治疗似乎降低了皮质醇反应并避免了血清淀粉样蛋白A的升高。总之，不使用全身麻醉但伤口立即喷洒PR的手术断尾方法，似乎是一种经济且更符合动物福利的羔羊断尾方法。
