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.
A Kentucky Thoroughbred farm is reaping the benefits of healthier mares and foals after making horse pasture renovations over the past year with guidance from University of Kentucky personnel.
Researchers are working to develop a fertility predictor test for colts and fillies to help breeders and buyers make informed decisions and potentially even help improve evaluations during breed inspections.
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.
Learn about equine oviduct anatomy and function and the role oviduct pathology on fertility from of Maria R. Schnobrich, VMD, Dipl. ACT, of Rood & Riddle Equine Hospital’s LeBlanc Reproduction Center.
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.
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.
Where do we go from here? Find out from Charlie Scoggins, DVM, MS, Dipl. ACT, who’s a fertility clinician at Rood & Riddle Equine Hospital in Lexington, Kentucky.
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.
Nocardioform placentitis affects late-gestation mares, causing abortion, stillbirth, or foals born alive but compromised.
Knowing which ovarian abnormalities are benign and which are pathogenic can help vets manage mare successfully.
This can pose a problem for mare owners working with a limited breeding window due to the short lifespan of the mare’s oocyte and the stallion’s sperm.
Dr. Regina Turner recaps research on endometritis, factors affecting pregnancy rates, treating placentitis, and more.
