What our clients say

Real results from veterinarians and breeders who have used bActivate on their most challenging problem mares.

Clinical Study
★★★★★

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.

Clinical Study
★★★★★

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.

What do I get, and do I need a veterinarian?

You receive a 10 ml vial of the bActivate activation growth medium. bActivate is a prescription veterinary product: it is instilled into the uterus by your veterinarian during early estrus, and the follow-up culture and any antibiotic treatment are handled by the veterinarian as well.

When should bActivate be used?

bActivate is indicated for mares that have failed to conceive despite breeding to fertile stallions, mares with recurring uterine fluid, mares with previous uterine infections, older broodmares with reduced uterine defence, and mares where antibiotics have previously failed. It is administered during estrus, one cycle before the intended breeding cycle.

What pregnancy rates has bActivate achieved in clinical studies?

In a study at Hagyard Equine Medical Institute led by Dr. Kristina Lu, 83% of 64 problem mares became pregnant after bActivate-guided diagnosis and veterinary treatment, and 70% of those with known outcomes produced a live foal. The study included no placebo group; the historic expected foaling rate for this group of mares is 15 to 50%. At Kildangan Stud (Godolphin), 89% of bred problem mares became pregnant (16/18), published as a congress abstract in the Journal of Equine Veterinary Science (2018).
