Disbudding and dehorning are common procedures on dairy farms. In a recent survey of Ontario dairy producers, 38% reported not using local anesthetic for these procedures. Use of pain control is important for both calf welfare and industry sustainability. Use of local anesthetic requires technical training, typically provided by a veterinarian, although online training videos also exist. Neither method has been studied for efficacy. Our objective was to compare an online module to hands-on training in teaching naïve participants (veterinary students) to effectively carry out a cornual nerve block and disbud a dairy calf. Participants were assigned to either an online or hands-on training group. Although no statistical differences were seen in success of the nerve block, online learners were less confident and had poorer technical skills. While online learning was surprisingly effective for a psycho-motor skill, best practices should include hands-on training.
去芽和去角是奶牛场常见的操作。在最近对安大略省奶牛养殖户的一项调查中，38%的养殖户报告称在这些操作中未使用局部麻醉剂。疼痛控制对于小牛福利和行业可持续发展都很重要。使用局部麻醉剂需要技术培训，通常由兽医提供，不过也有在线培训视频。两种方法的效果都尚未得到研究。我们的目标是比较在线模块和实践培训，看哪种方式能更好地教会新手参与者（兽医专业学生）有效实施角神经阻滞并给奶牛犊去芽。参与者被分配到在线培训组或实践培训组。尽管在神经阻滞的成功率上未观察到统计学差异，但在线学习者信心较低且技术技能较差。虽然在线学习对于一项心理运动技能来说出人意料地有效，但最佳做法应包括实践培训。
