Problem getting your mare in foal?
bActivate is the best solution.
70-80% of all problem mares carry a hidden uterine infection with a clear negative effect on fertility. bActivate gives barren mares a second chance — by activating the dormant infections that standard tests miss.

How bActivate works?
Dormant bacteria are difficult to diagnose by standard techniques and highly tolerant to antibiotic. Efficient handling thus requires re-activation of the bacteria. This can be achieved by instillation of bActivate, a bacterial growth medium, into the uterus.
READ MOREWhat is bActivate?

When to use?
5-15% of all mares are not pregnant at the end of the breeding season, despite fertilised stallions and supervised by experienced veterinarians.
READ MOREHow to use?
bActivate is to be used in mares with reduced uterine defense mechanisms and in mares suspected of having a chronic subclinical infection.

Our products
The concept behind bActivate (promoting bacterial-activation) was discovered by Morten Rønn Petersen, DVM, PhD and Professor Anders Miki Bojesen, DVM, PhD.
SHOPThe Men Behind bActivate
Ten percent of all mares struggle to get in foal. Now two Danish researchers have identified what might be wrong and produced a product, which can facilitate diagnostics. Veterinarians at the world's largest equine hospital in Kentucky have successfully tested the product.

Real results from veterinarians and breeders who have used bActivate on their most challenging problem mares.
“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.”
“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.”
“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 effectively. It 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.”
“Our 18-year-old mare had failed for five consecutive seasons. After bActivate she was confirmed strongly positive for Streptococcus — an infection standard testing had completely missed. She was treated, covered in September, and for the first time in five seasons there was no fluid present at ovulation. She is now 34 days in foal. This is the first time a pregnancy has not involved invasive flushing, excessive drugs and a battle to hold it.”
