Abstract

The deposition of semen, bacteria and debris in the uterus of the mare after breeding normally induces a self-limiting endometritis. The resultant fluid and inflammatory products are cleared by 48 hours post cover. Mares that are susceptible to persistent post-breeding endometritis (PPBEM) have impaired uterine defence and clearance mechanisms, making them unable to resolve this inflammation within the normal time. This persists beyond 48 hours post-breeding and causes persistent fluid accumulation within the uterus. Mares with PPBEM have an increased rate of embryonic loss and a lower overall pregnancy rate than those without the condition. To enhance conception rates, mares at high risk need optimal breeding management as well as early diagnosis, followed by the most appropriate treatment. This article reviews the pathogenesis, diagnosis and treatment of PPBEM and the management of affected mares.

A healthy vulva. The labiae of the vulva are symmetrical and the vulva itself is properly closed.
Figure 1b
Figure 1b
Altered conformation of the vulva. The labiae do not create a proper seal and the rectum is displaced cranially, allowing the vulva to be pulled dorsal to the ischiatic arch, causing constant faecal contamination of the vulva and vestibule.
