* The presence of a male can stimulate the onset of cyclic activity in some species (see 'Ram Effect' for more detail).
* In sows and gilts, removing piglets will cause a more rapid return to cyclic activity post-partum.
* If litters are weaned from a group of sows at the same time, there will also be some synchronisation of oestrus.
* Also in gilts and sows, the stress of changing environment or transport stress can stimulate the onset of oestrus post-partum.
