Randomized Controlled Trial[Effect of isoflurane inhalation anesthesia on postoperative pain due to castration of piglets].
Since April 2006 piglets in Germany can only be castrated without anesthesia in the first 7 days of life. However, a castration is a painful experience even for an animal of this young age. Whether the castration under isoflurane-anesthesia is a reasonable alternative to castration without anesthesia was tested in the following investigation at 206 4 to 6 day old piglets. ⋯ Cortisol after castration was significantly lower in piglets with an application of Meloxicam prior to castration. The pain caused by castration is an explanation for the differences in cortisol-concentration between castrated and not-castrated animals. Regarding those results, we assume that castration with isoflurane-anesthesia does not fulfil the demand for reducing pain after castration compared to castrating piglets without anesthesia.
