Endometritis in Mares – How bActivate Can Improve Fertility

Endometritis is one of the most common causes of infertility in mares, leading to repeated failed pregnancies and a higher risk of early embryonic loss. If your mare is struggling to conceive or maintain a pregnancy, a bacterial imbalance in the uterus could be the underlying issue.

What is Endometritis?

Endometritis is inflammation of the uterine lining, often caused by bacteria such as Streptococcus zooepidemicus (Strep zoo), E. coli, or Klebsiella pneumoniae. It can be classified as either acute or chronic and is typically triggered by:

🔸 Natural breeding or artificial insemination
🔸 Poor uterine clearance mechanisms
🔸 Retained fluid or post-foaling complications

A mare suffering from chronic bacterial endometritis may become barren, meaning she fails to conceive despite multiple breeding attempts.

How Does Endometritis Affect Fertility?

Mares with endometritis often struggle to clear bacteria and inflammatory debris from the uterus, leading to:

❌ Low conception rates
❌ Early embryonic loss
❌ Persistent uterine infections

While traditional treatments such as antibiotics and uterine flushes are commonly used, they can disrupt the natural uterine microbiome and may not provide long-term solutions.

Bactivate – A Natural Solution for Uterine Health

Bactivate is a biological treatment designed to support a healthy uterine microbiome, reducing harmful bacteria and promoting an environment that supports conception and pregnancy.

How Does Bactivate Work?

Reduces harmful bacteria like Strep zoo
Restores microbial balance in the uterus
Enhances the mare’s immune response against infections
Supports overall fertility and increases conception rates

Why Choose a Biological Approach?

Overuse of antibiotics can lead to resistance and further imbalances in the uterine microbiome. By choosing a biological alternative like Bactivate, you can help your mare naturally regulate bacteria levels, reduce inflammation, and increase the chances of a successful pregnancy.

Conclusion

If your mare is barren or struggling with recurrent infections, bacterial endometritis may be the root cause. Supporting uterine health with Bactivate can be the key to improving fertility naturally.

  • Potent new tool for the problem mare!

    bActivate enabled us to identify chronically infected mares, which were found to be clean on culture and cytology using routine diagnostics. We will use it for our problem mares in the coming season.
