This research compared ring block lidocaine anesthesia (L) and compression (C) for velvet antler removal in elk. Thirty-two wapiti were given 1 mg/kg body weight of zuclopenthixol acetate. The next day, they were restrained in a hydraulic chute and given either a compression device or a lidocaine ring block on the antler pedicle. Behavioral and physiological responses to treatment application and antler removal were recorded, and blood was collected for cortisol analysis. During application of L and C, increases in mean heart rate and systolic arterial blood pressure were greater in the C treatment group (P < 0.05, and P = 0.05, respectively). When antler was removed, more behavioral responses occurred in the C treatment group (P = 0.02) and its median behavior score was higher (P = 0.03). Mean heart rates increased for both treatment groups when antlers were removed (P < 0.01). It was concluded that application of C may be painful, and that C was not as effective as L for analgesia for velvet antler removal.
本研究比较了环形阻滞利多卡因麻醉（L）和压迫法（C）在去除麋鹿鹿茸时的效果。32只马鹿被给予1毫克/千克体重的醋酸珠氯噻醇。第二天，将它们限制在液压斜槽中，对鹿茸基部要么使用压迫装置，要么进行利多卡因环形阻滞。记录对处理应用和去除鹿茸的行为和生理反应，并采集血液进行皮质醇分析。在应用L和C的过程中，C处理组的平均心率和收缩期动脉血压升高幅度更大（分别为P < 0.05和P = 0.05）。去除鹿茸时，C处理组出现更多行为反应（P = 0.02），其行为中位数评分更高（P = 0.03）。去除鹿茸时，两个处理组的平均心率均升高（P < 0.01）。得出的结论是，应用C可能会引起疼痛，并且在去除鹿茸的镇痛方面，C不如L有效。
