Does your breeding stallion have a tinge of blood in his semen after a routine collection for artificial insemination? Or do you notice physical lesions on his genitalia during pre- or post-breeding washing? These are tell-tale signs of hemospermia—literally, blood in the semen—a condition that is not only detrimental to fertility, but can als...
While your veterinarian is stitching wounds, delivering foals, and monitoring colics, researchers from around the world are publishing research that often advances the collective of horse health care. So to bring busy practitioners up to speed on the top studies in a variety of fields, a panel of veterinarians presents a news-type program each year at the...
Researchers have confirmed the importance of including exposed mares when conducting surveillance for contagious equine metritis (CEM) in the recent South African outbreak, along with specific stallion sampling and screening methods in that country for the venereal disease.
Veterinarians and researchers with interests in equine reproduction gathered Aug. 7-10 in Louisville, Ky., for the 2013 American College of Theriogenology (ACT) Symposia and Conference. On the last day of the event presenters Mary Beth Stanton, DVM, Dipl. ACT, of Equine Veterinary Reproduction Specialists, in Ocala, Fla., and Audrey Kelleman, DVM, Dipl. A...
The term "do-it-all-dad" just took on a whole new meaning: Cornell University researchers have recently determined that, in equids at least, it’s the father’s genes that take the lead in developing the mare's placenta.
Because breeding is a business, having a veterinarian evaluate your stallion's semen to determine his fertility (or lack thereof) is a key component of a breeding soundness examination. But semen evaluations are not always black and white, and there are many types of tests your veterinarian can perform. So at the 2013 Society for Theriogenology Confer...
Having trouble getting your mare pregnant? It might be time to take a good look at her weight and metabolic condition. Some veterinarians now believe that metabolic diseases likely have a negative impact on equine reproduction.
A broodmare battling chronic laminitis, a stallion with recurrent uveitis, and a maiden mare with persistent tendinitis: While these horses and their conditions are each distinct, the animals do share the potential for exhibiting pain-related fertility problems. A University of Florida (UF) veterinarian described how equine pain might influence reproducti...
A gelding’s gonads are gone, but he’s still susceptible to problems developing in his reproductive tract, particularly abnormal growths in the accessory sex glands. Take, for example, prostatic tumors, which can cause difficulty urinating or blood to show up in the urine. When a gelding has signs of discomfort associated with the urogenital tr...
The coming of spring is, in some ways, a rebirth. It's the time when many horse owners dig out their grooming supplies and clippers and breathe fresh life into their furry charges (aka, the Spring Cleaning Frenzy). Some owners have "The Frenzy" down to a science, but others might forget to clean of one of the darkest—and possibly dirti...
New research from the University of Kentucky (UK) suggests that genetic factors play a role in determining stallion susceptibility to equine arteritis virus (EAV) infection.
Veterinary researchers publish scores of scientific papers annually, but if practitioners are out examining and treating patients they don't necessarily have time to brush up on every study's take-home message. The annual Kester News Hour presentation at the American Association of Equine Practitioners' convention gives practitioners a chance ...
If your stallion needs to have a testicle removed due to disease, neoplasia (tumor), or severe trauma, don't worry: Stallions can still lead productive lives as studs with only one testis, assures a researcher from Texas A&M University.
We often talk about the horse world in the national context, but at the global level the World Organization for Animal Health (OIE) assists to protect our horses and the horse industry from infectious disease and to put regulations in place for safe trade and transport between countries.
Veterinarians and breeding farm managers regularly examine stallion semen samples under a microscope to check sperm motility, especially samples from horses with suspected fertility issues. But while they can check sperm for this common fertility measure on the farm or in the average veterinary clinic, evaluating sperm morphology--to ensure the head, midp...
Outside of the breeding season, most stallions are fed according to their maintenance requirements or slightly above that amount. However, as breeding season approaches, stallion owners might consider a few key points about their studs' nutritional needs.
University of Kentucky (UK) Ag Equine Programs will host a UK Equine Showcase Jan. 18 and the 4th Annual Kentucky Breeders' Short Course Jan. 19, both at the UK Veterinary Diagnostic Laboratory, 1490 Bull Lea Road, Lexington.
Afraid your stallion is a dud at stud? Well, don't be so quick to judge: Many factors influence stallion fertility, say our sources, and a good number of these can be managed and improved.
