Equine post-breeding endometritis: A review.

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.

This research article examines persistent post-breeding endometritis in mares (female horses), a condition which leads to increased rates of embryonic loss and lower pregnancy rates due to impaired uterine defences and clearance mechanisms. The paper discusses the causes, diagnosis, and treatment of this condition, as well as the optimal management of affected mares to enhance conception rates.

Pathogenesis of Persistent Post-Breeding Endometritis

  • The study explains that following breeding, the deposition of semen, bacteria, and debris in the uterus typically results in an endometritis (inflammation) which is usually self-limiting. This means that it resolves on its own within 48 hours, thanks to efficient uterine defence and clearance mechanisms.
  • However, in cases of Persistent Post-Breeding Endometritis (PPBEM), these mechanisms are impaired, and the mares cannot clear the inflammation and resultant fluid within the usual time. Instead, the inflammation persists for over 48 hours, causing consistent fluid accumulation in the uterus.

Diagnosis and Treatment of PPBEM

  • For mares susceptible to PPBEM, the inflamed condition of their uterus and the persistent fluid accumulation leads to a higher rate of embryonic loss and decreased overall pregnancy rates compared to mares unaffected by the condition.
  • Therefore, early diagnosis is crucial. Once diagnosed, the most appropriate treatment must be provided to alleviate the condition.

Management of Affected Mares

  • The article suggests best practices for managing mares with PPBEM to enhance their conception rates. This includes providing optimal breeding management measures; however, specific steps are not elaborated in the abstract.
  • The understanding being that mares at risk need enhanced care when being bred, as well as careful monitoring post-breeding to recognise any potential issues early on.

Summary

  • The essence of this research is to improve understanding of PPBEM in mares, its causes, and its consequences for mare fertility. Furthermore, it discusses strategies for managing affected mares to mitigate impacts on breeding potential.
