Podcast
If you're a breeder, veterinarian, or equine professional, this podcast is a must-listen. Professor Anders Miki Bojesen and Dr. Morten Rønn Petersen share expert insights on one of equine reproduction's most stubborn challenges: the problem mare.
Why do some mares fail to conceive despite multiple attempts, normal cycles and clean swab results? The answer often lies in dormant Streptococcus zooepidemicus — a hidden bacterial infection that evades standard diagnosis and resists conventional antibiotic treatment.
The podcast and video series cover the biology of dormant infections, diagnostic best practices, the bActivate activate-first protocol, and real-world case studies from leading breeding operations including Godolphin and Hagyard Equine Medical Institute.

Real results from veterinarians and breeders who have made bActivate part of their reproductive protocol.
“We incorporated bActivate into our standard reproductive work-up for problem mares at Hagyard. Out of 64 mares that had failed to conceive for at least 3 cycles, 83% became pregnant following bActivate activation and targeted antibiotic treatment. Nearly half had a dormant Streptococcus infection that standard culture had completely missed. It changed the way we approach the problem mare.”
“We used bActivate on 19 of our most persistent problem mares — horses that had been barren for over a year despite every conventional treatment we tried. 89% of them got in foal. What really opened our eyes was how many had a hidden infection that standard swabs had never detected. It is now a routine part of our protocol at Kildangan.”
“We have been using bActivate on several mares — all got pregnant and most of them in first try with frozen semen!”
“bActivate is an excellent tool that allows us as reproductive vets to do our job as effectively as possible. When you compare the cost to the expense of a mare that fails to conceive — or worse, never produces a foal — bActivate is both a smart and cost-effective solution in the long run.”
“I used bActivate and after just one covering got a colt foal — after 3 years of hardship where the mare went in foal but never managed to produce a live foal. I cannot recommend bActivate enough.”
