Since September 1, 2001, castration of male calves and small ruminants in Switzerland is not allowed without anesthesia. The use of rubber rings for that purpose is forbidden. This change of the legislation has been claimed by the Swiss consumers and is aimed to increase the animal welfare. The current paper provides a review of the different techniques of anesthesia and castration that may be advocated in male ruminants. Sedation with xylazine and injection of lidocaine in the area of the base of the scrotum, followed by closed castration with the Burdizzo represents a safe technique for painfree castration of calves and lambs.
自2001年9月1日起，在瑞士，未经麻醉不得对雄性犊牛和小反刍动物进行去势。禁止为此目的使用橡皮圈。这项立法的改变是瑞士消费者要求的，旨在提高动物福利。本文综述了雄性反刍动物中可能提倡的不同麻醉和去势技术。用赛拉嗪镇静并在阴囊基部区域注射利多卡因，然后用布尔迪佐钳进行闭合去势，是犊牛和羔羊无痛去势的一种安全技术。
