In fall 2004, a survey of a representative sample of 1185 Swiss suckler beef farmers was carried out by questionnaire (return rate 51.9%). 32.7% of the respondents castrated their calves without the help of a veterinarian, 37.8% mandated a veterinarian to carry out the castrations and 29.4% did not castrate their bull calves at all. On average, 8 calves were castrated per farm and year at an average age of 7 days when the castration was carried out by a farmer or 34 days when the castration was carried out by a veterinarian. Almost all farmers castrated their calves with the rubber ring, and a majority considered no other method as feasible. 73.9% of the veterinarians used the Burdizzo technique, 14.9% applied rubber rings, and 11.2% performed a surgical procedure. 22.6% of the farmers and 85.4% of the veterinarians used sedation; local anaesthesia was performed in 32.1% of the castrations carried out by farmers and in 84.5% of the castrations carried out by veterinarians. 65.7% of the farmers were concerned by the change of the Swiss Animal Protection Ordinance (2001), when pain relief became mandatory. 47.6% of these farmers changed their castration routine: 53.1% now mandated a veterinarian, 33.0% used sedation or local anaesthesia and 8.9% abandoned castration of their calves. 59.8% of the farmers intended to participate in a future course for laymen, to study and train the technique of local anaesthesia for castration. Castration of their calves is for many suckler beef farmers an inevitable husbandry procedure. The political goal, that all calves shall be castrated with local anaesthesia can only be reached when livestock owners are informed about the distress caused by the castration and convinced of the benefit of the local anaesthesia. Veterinarians are important information carriers in this process. The implementation also produces work, be it the more complex castration procedure or the education of the farmers who want to carry out the local anaesthesia themselves.
2004年秋季,通过问卷调查对1185名瑞士肉牛养殖户的代表性样本进行了调查(回复率为51.9%)。32.7%的受访者在没有兽医帮助的情况下对小牛进行去势,37.8%的受访者委托兽医进行去势,29.4%的受访者根本不对公牛犊进行去势。每个农场每年平均去势8头小牛,养殖户进行去势时小牛的平均年龄为7天,兽医进行去势时小牛的平均年龄为34天。几乎所有养殖户都用橡皮圈给小牛去势,并且大多数人认为没有其他可行的方法。73.9%的兽医使用布尔迪佐去势法,14.9%的兽医使用橡皮圈,11.2%的兽医进行外科手术。22.6%的养殖户和85.4%的兽医使用镇静剂;养殖户进行的去势手术中有32.1%实施了局部麻醉,兽医进行的去势手术中有84.5%实施了局部麻醉。65.7%的养殖户对瑞士动物保护条例(2001年)的变更表示关注,该条例规定必须进行止痛。这些养殖户中有47.6%改变了他们的去势常规做法:53.1%的养殖户现在委托兽医,33.0%的养殖户使用镇静剂或局部麻醉,8.9%的养殖户放弃对小牛去势。59.8%的养殖户打算参加未来面向非专业人员的课程,学习和培训小牛去势的局部麻醉技术。对许多肉牛养殖户来说,给小牛去势是一项不可避免的养殖程序。只有当牲畜养殖户了解去势造成的痛苦并相信局部麻醉的益处时,才能实现所有小牛都用局部麻醉去势这一政治目标。兽医在这一过程中是重要的信息传播者。实施过程也会产生工作,无论是更复杂的去势程序,还是对想要自己实施局部麻醉的养殖户进行培训。
