A group of cattle was dehorned while restrained with an electro-immobiliser. The level of stress was evaluated by measuring serum cortisol and comparisons made with alternative handling methods. Serum cortisol levels rose significantly in groups that were dehorned compared with non-dehorned controls, but no significant difference was noted between groups dehorned using local anaesthesia, electro-immobilisation, or no pre-treatment. The degree of haemorrhage resulting from dehorning was not significantly different between the groups. It was concluded that the immobiliser may be painful on application and should not be relied upon to produce analgesia.
一组牛在使用电麻器固定时进行了去角处理。通过测量血清皮质醇来评估应激水平，并与其他处理方法进行比较。与未去角的对照组相比，去角组的血清皮质醇水平显著升高，但在使用局部麻醉、电麻或未进行预处理的去角组之间未观察到显著差异。去角导致的出血程度在各组之间没有显著差异。得出的结论是，电麻器在使用时可能会引起疼痛，不应依赖它来产生镇痛效果。
