Is it safe to breed a mare who has equine metabolic syndrome and a history of laminitis? Reproduction expert Dr. Ryan Ferris offers insight.
Equine reproduction specialist Dr. Ryan Ferris explains basics new horse breeders need to know, including mare estrus cycles and selecting fresh vs. frozen semen.
Bacterial endometritis that is refractory to traditional antimicrobial treatment is a significant challenge to the equine breeding industry. Fortunately, several therapeutic options are currently available to clinicians for the treatment of biofilm-associated endometritis in horses.
The University of Kentucky Ag Equine Programs will host its 8th Annual UK Equine Showcase in conjunction with an Equine Vet Continuing Education session (formerly known as the Kentucky Breeders’ Short Course) Jan. 25-26, 2019.
Researchers tested a sulfadiazine and trimethoprim suspension specifically designed for oral administration with positive results.
While some species develop a local immune response, sending special protective cells to the uterus itself, mares don’t, researchers learned recently. Rather, they appear to send those cells elsewhere as soon as semen enters the uterus. Where they go, nobody knows (yet).
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.
