Is there a difference in performances or causing boar taint when males and females are bred in the same pens versus when they are bred separated? What is the situation in the various European countries? Are male and female pigs bred in the same pens or separately?

International research results provide a mixed picture. Some are in favour of mixed pens, others in favour of separate housing.
Research in the Sterksel Swine Innovation Centre does not show a preference for one of the two methods. Both give comparable results.
At the moment there is nog Information or research results from other countries.  Dutch pig farmers breed their male and female pigs in most cases in separate pens.
There is no information available about the situation in other EU countries.
