Castration is a common management practice among livestock producers, and animal welfare concerns exist following this procedure. The study's aim was to compare the behavior, performance, and blood parameters between calves castrated with a lidocaine-infused castration band (Lidoband™; LLB) to a standard band with no pain relief. In this blinded, randomized controlled trial, 26 male beef-dairy cross calves were followed for 7 weeks post banding. There were no significant differences between treatment groups in regard to overall body weight, average daily gain (ADG), feed conversion (G:F), clinical illness scores, banding site scores, and approach tests. However, there were treatment differences in the weekly ADG and G:F ( < 0.05). There was a significant treatment by time interaction between the number of lying bouts and the average stand bout time ( < 0.05). There was also a significant treatment difference in the number of wound licks ( < 0.05). Overall, band castration presented acute and chronic pain, regardless of treatment. Performance, analyzed weekly, and behavioral patterns around the time of wound granulation (days 21-35 post castration) demonstrated positive outcomes for calves in the LLB group. Banding with an LLB proved to be beneficial in terms of both performance and behavioral aspects, implying greater animal welfare.
去势是家畜养殖者常用的管理措施,但该操作会引发动物福利问题。本研究的目的是比较使用注入利多卡因的去势带(Lidoband™;LLB)去势的犊牛与使用无疼痛缓解功能的标准去势带的犊牛在行为、生长性能和血液参数方面的差异。在这项双盲随机对照试验中,26头肉用-乳用杂交雄性犊牛在佩戴去势带后被跟踪观察7周。在总体体重、平均日增重(ADG)、饲料转化率(G:F)、临床疾病评分、去势带佩戴部位评分和接近测试方面,各治疗组之间没有显著差异。然而,在每周的ADG和G:F方面存在治疗差异(<0.05)。躺卧次数与平均站立时长之间存在显著的治疗时间交互作用(<0.05)。伤口舔舐次数也存在显著的治疗差异(<0.05)。总体而言,无论采用何种治疗方法,去势带去势都会带来急性和慢性疼痛。每周分析的生长性能以及伤口结痂期(去势后21 - 35天)前后的行为模式表明,LLB组的犊牛有积极的结果。事实证明,使用LLB进行去势在生长性能和行为方面都有益处,这意味着动物福利得到了更大保障。
