Equine Vet J. Most stallion spermatozoa are viable for at least 48-72 hours after mating, although records will ultimately indicate if the semen from a particular stallion is not viable after 48 hours.4 This early mating allows more time for drainage of fluid via an open estrous cervix and also utilizes the natural resistance of the tract to inflammation during estrus. This is because the foal does most of its growth during the final months of pregnancy. Reduced myometrial contractions, poor lymphatic drainage, a large, overstretched uterus and cervical incompetence are predisposing factors for persistent-mating induced endometrititis.3, It is particularly important to recognize and appropriately manage older maiden mares; in many cases these mares are susceptible to post-breeding endometritis even though they have never been bred before.

Mares susceptible to mating-induced endometritis are known to accumulate fluid in the uterus as a result of impaired clearance of inflammatory products. It is not uncommon for an inexperienced mare to foal later than expected. [28]Although an experimentally-induced placentitis may not relate exactly to a naturally occurring case, this data does provide strong evidence that suitable treatment can significantly increase the likelihood of a successful outcome if that treatment is initiated at an early enough point.

Relaxation of the muscles of the croup 7-19 days prior to foaling; relaxation around the tail head, buttocks, and lips of the vulva.

That factor could result in a return of an inaccurate diagnosis of the causative agent, although inclusion of treatment of any identified likely organisms in a treatment protocol is more likely to prove beneficial than unnecessary. 64:528-534 (2003) A microdialysis model to detect drugs in the allantoic fluid of pregnant pony mares.
