Surveyed attitudes, perceptions and practices in Norway regarding the use of local anaesthesia in piglet castration.

The last two years piglet castration in Norway has been performed by veterinarians and with the use of anaesthesia. In order to evaluate this new policy, veterinarians and pig producers were asked to fill out a questionnaire regarding their experiences with the new castration practices. The answers showed that the piglets were most often castrated using a combination of subcutaneous and intratesticular administration of lidocaine with adrenaline at an average age of 10 days. The effect of the anaesthesia was regarded as good by 54% of the veterinarians and 19% of the producers. Post-operative complications were rare. The overall evaluation showed that two-thirds of the veterinarians, but only one-third of the pig producers were satisfied or very satisfied with the implemented policy. However, while two-thirds of the pig producer had a negative attitude to the policy before it was implemented, only one-third were dissatisfied after two years experience.
