The puerperium is short, with rapid involution and good conception rates at the first postpartum oestrus.
==Involution==
Lochial discharge is slight in most mares and usually ceases 24-48 hours after foaling. [[Female Reproductive Tract - Horse Anatomy#Uterus|Uterine horns]] shrink rapidly, reaching pre-gravid size by day 32 postpartum. The [[Female Reproductive Tract - Horse Anatomy#Cervix|cervix]] remains slightly dilated until after the first oestrus. Involution delayed by retained foetal membranes, as in other species.
==Restoration of the Endometrium==
The [[Female Reproductive Tract - Horse Anatomy#Uterus|endometrium]] is capable of sustaining a pregnancy (fully restored) by 13-25 days postpartum. Small amounts of villous debris attached to maternal crypts are removed by autolysis. Maternal cryps disappear due to:
*Lysis
*Shrinkage of endometrial epithelial cells
*Condensation of contents of epithelial cells
*Collapse of the crypt lumen
==Return to Ovarian Cyclicity==
This is rapid in the mare. '''Foal heat''' occurs 5-12 days postpartum. Follicular activity after day 2 postpartum.
==Bacterial Elimination==
Bacterial contamination of the [[Female Reproductive Tract - Horse Anatomy#Uterus|uterus]] from the environment is frequent. Organisms are usually eliminated during foal heat or disappear at second postpartum oestrus.
