The Federation of Veterinarians of Europe (FVE) carried out in November 2015 a survey on pig castration in order to see the progress made in respect to the European declaration on pig castration. The end goal of this declaration is to phase out the surgical castration of pigs by 2018. The declaration also requests that since 1 January 2012, surgical castration of pigs shall only be performed with prolonged analgesia and/or anaesthesia.
