AASV Position Statement: Castration of Swine

Castration of male pigs is performed to reduce aggressive behaviors and improve the palatability of pork. The AASV supports the use of procedures that reduce pain, including the development and approval of practical analgesic and anesthetic protocols that improve piglet outcomes. Currently, U.S. commercial market pig processors do not accept uncastrated male pigs for sale into the domestic or foreign food supply. Surgical castration should be performed early and sufficiently prior to weaning such that no open wounds remain at the time of weaning. Clean, sharp equipment must be used to minimize pain and risk of infection. If surgical castration is performed after weaning, analgesia and/or AMDUCA-permissible anesthetic protocols should be used.  Immunological castration is an alternative technology that prevents boar taint.
