The performance of tail biting and other harmful social behaviours is a common problem on pig farms. Many risk factors relating to tail biting have been identified, but the problem remains intractable. One contributory factor may be the genetic makeup of pigs but, as with most pig behaviour, there has been little research into the genetic basis of its expression. The aim of the current experiment was to investigate the genetic component of harmful social behaviours, such as tail biting, by assessing breed differences in the predisposition to perform these behaviours.
