Résumé
Since the amendment of the animal welfare law in Germany in April 2006, castration of piglets without anesthesia is only allowed in the first seven days of life. However, neonates are capable of feeling pain and react more sensitive to pain than adults. Accordingly we expect that castration without anesthesia will be unaccepted in Germany in the future as castration without anesthesia will be forbidden in Switzerland from 2009 on. Denmark and the Netherlands strive for an embargo of the castration without anesthesia and Norway is already asking for an elimination of pain during castration. In Switzerland castration under isoflurane-anesthesia is considered to be a good alternative for the castration without anesthesia. Whether isoflurane-anesthesia is able to reduce stress caused by castration adequately or anesthesia, especially anesthetization that often provokes defensive reaction, is stress for the animal itself was tested in the following investigation. To get an objective statement about the stress of the animals, concentrations of epinephrine and norepinephrine were detected before and immediately after castration/fixation with or without anesthesia. Five day old, healthy animals were divided into four groups. Animals of group A (n = 10) were only fixed without anesthesia, animals of group B (n = 10) were fixed and castrated without anesthesia. In group C (n = 10) the animals were only fixed under anesthesia and the animals of group D (n = 11) were fixed and castrated
