Bonobos show a particularly pronounced sexual activity and an extraordinarily broad spectrum of sexual contacts for primates. These also extend to non-reproductive life phases and partner combinations. For example, homosexual contacts and sexual contacts between young animals or with adults are frequent, and females are ready to mate throughout the menstrual cycle. Bonobos use sexual contacts not only for reproductive purposes, but also in the context of social conflicts, where they have a clear tension-reducing or peacemaking function.

At this time the shepherd must also warm newly-born, supercooled lambs inside the house and feed them artificially.
