Researchers know that feeding horses ground endophyte-infected tall fescue results in palmar artery vasoconstriction, so scientists tested whether broodmares could experience decreased blood flow to the uterus, which could negatively impact their foals.
Dini hopes his current research projects will help improve the understanding of equine placental development.
Mares receiving the synthetic hormone reFSH went from anestrus (not cycling) to ready to breed within about a week, researchers found in a recent study.

Researchers have learned that foals and dams appear to prefer looking at each other with their left eyes and keeping each other in their left field of vision in most situations.
A mare’s attraction to a stallion—specifically, to his body odors, or “MHC”—affects pregnancy success rates. And, researchers found, mares appear to prefer stallions with MHCs that differ from their own.
Carleigh Fedorka, PhD, a postdoctoral scholar at the University of Kentucky Gluck Equine Research Center, started the campaign to fund her study “Hormone therapy: Suppressing your mare’s estrous, or suppressing her immune system?”
When veterinarians detected pregnancy loss in horses early enough for mares to be rebred, 57.3% delivered a live foal the following spring. Of those, mares 3 to 8 years old had a 73% live-foaling rate.
Horse owners might want to have their mares’ ovaries surgically removed for a variety of reasons, including to prevent pregnancy, get rid of tumors, or, most commonly, resolve behavioral issues.
Post-foaling colic is a significant threat for mares. Dr. Anthony Blikslager describes what to look for and how to respond if your mare colics following foaling.
If surgery requiring general anesthesia must be performed on pregnant mares, the safest time window is Days 40-220 of gestation, researchers concluded.
Equine herpesvirus-1, or EHV-1, infection can result in late-term abortion in pregnant mares.
While removing mares’ ovaries can be successful in remedying aggressive behavior, other estrous behaviors can persist even following surgery.
A reproductive specialist describes techniques to help clinicians overcome common challenges in embryo recovery and recipient mare management.
Vets should perform a careful assessment of a mare’s hormonal status to determine whether there’s a definitive, repeatable relationship between it and her undesirable behavior.
