Boars used for semen collection in artificial insemination studs require specific welfare management to prevent frustration and stereotypy.
Boars in AI stud operations are often housed in individual pens without social contact - a welfare compromise for a highly social species. The motivation to social interact and express sexual behaviour, combined with confinement, creates frustration that may manifest as stereotypic behaviour. Improved housing with social contact or at least visual and olfactory contact significantly improves boar welfare.
