** Delay in lochial expulsion due to weak myometrial contractions.
** Delay in lochial expulsion due to weak myometrial contractions.
==Factors Influencing the Puerperium==
=== Uterine Involution ===
==== Age ====
* More rapid in primiparia than pleuriparia
==== Season ====
* More rapid in spring and summer months.
==== Suckling vs Milking ====
* Results are contradictory
* May be a breed influence on the time taken to return to ovarian cyclicity
==== Climate ====
* Heat stress can accelerate and inhibit the speed of involution.
==== Periparturient Abnormalities ====
* Dystocia, retained placenta, hypocalcaemia, ketosis, twin calves and metritis delay involution.
* Periparturient problems cause a delay of the process of involution by ~5-8 days.
==== Delayed Return to Ovarian Cyclicity ====
* Inhibits involution
=== Restoration of the Endometrium ===
* Retained foetal membranes and metritis inhibit healing.
* Return to ovarian cyclicity may have an influence.
=== Return to Ovarian Cyclicity ===
This can be affected by; periparturient abnormalities, milk yield, nutrition, breed, parity, season, climate and suckling intensity and milking frequency.
