The most common cause of late-term abortion in mares is placentitis, a term that describes an inflammation of the placenta. Nocardioform placentitis is somewhat less common, but a significant upswing in cases occurred in Kentucky two years ago,
How big will that foal be when it’s fully grown? Mature size is influenced by nutrition, health history, breed, and the foal’s genetics, among other factors, but a rough estimate of adult height can be gotten by using a measuring tape.
Breeders often use artificial light to entice mares to cycle earlier in the year than they would normally so they can be bred in late winter or early spring.
In order to keep broodmares comfortable and to give them the best chance of producing healthy foals, managers need to schedule routine care and give some thought to proper nutrition.
The use of frozen-thawed semen to impregnate has become a widespread practice, but careful consideration of the mare and her reproductive capabilities help ensure success with this method of artificial insemination.
If you have even the slightest idea that you may want to breed your mare next spring, it’s never too early to think about the process of getting the mare into the best condition to achieve a successful conception, full-term pregnancy, and live birth of a healthy foal.
Loss of pregnancy can be due to various factors including infection, morphologic defects in the embryo, or slowed embryonic growth. One possible cause of early pregnancy loss in mares is thought to be an overactive immune response.
Contagious equine metritis and equine viral arteritis are sexually transmitted diseases (STDs) that affect horses, causing problems such as low conception rates, abortion, and sick or weak newborn foals.
Researchers from the University of Kentucky, University of California, and Colorado State University investigated the efficacy of an equine recombinant follicle stimulating hormone (reFSH) in noncycling mares housed under natural light conditions.
Horses have a gestation period that lasts approximately 340 days. If that sounds like a long time to wait for the baby to be born, you’d be no better off raising llamas (350 days) or donkeys (365 days).
