Part I: understanding pain in pigs-basic knowledge about pain assessment, measures and therapy.

Background: Pigs can suffer from pain due to spontaneously occurring diseases, wounds, injuries, trauma, and physiological conditions such as the farrowing process; however, this pain is often neglected. To increase knowledge and awareness about this phenomenon, the current article presents a scoping review of basic and new approaches for identifying, evaluating, and treating pain in pigs.

Methods: A scoping review was conducted with results from a search of the electronic database VetSearch and CABI.
