Extensive Equine Reproductive Services in Portland & Southwest Washington

Our goal at Columbia Equine Hospital is to maximize your animal’s reproductive success by providing high-quality individualized care and attention to stallions, mares, and foals. We have an on-site breeding facility with a safe and quiet breeding barn, teasing wall, and collection phantom, stocks, spacious mare/foal stalls, and a reproductive laboratory for embryo transfer and semen freezing, and shipping. Most reproductive services are also available on an ambulatory basis.

Equine Reproduction Services Available at Columbia Equine Hospital At the Columbia Equine Hospital reproduction center, our experienced staff handle semen evaluation, and semen shipment. Mares are bred at the hospital and in the field, with frozen semen inseminations taking place in the hospital. Embryo transfer and uterine endoscopy are also available from the reproductive center.


Breeding Soundness Exam

Mare

Prior to purchasing a new mare or breeding a maiden mare, we recommend an external and internal evaluation of the reproductive tract. Vulvar or pelvic conformation defects may result in wind-sucking or urine pooling and subsequent contamination of the uterus. Cervical scarring from previous foaling trauma can inhibit complete uterine evacuation during estrus, thereby reducing fertility.

Ultrasound examination of both the uterus and the ovaries can reveal tumors, cysts, and infection that may affect reproductive success. Endoscopic evaluation allows a thorough inspection of the reproductive tract that can reveal localized lesions affecting fertility. Uterine cytology and culture is beneficial in diagnosing unapparent infection and/or inflammation. Uterine biopsy reveals histological defects in the uterine wall that may inhibit implantation of the embryo. These diagnostics are crucial in the problem mare with a history of poor reproductive performance.


Artificial Insemination

Artificial insemination allows breeding of your mare to a stallion from anywhere in the world without the risk of disease or injury during mating. Managing the estrus cycle with ultrasonography reduces the number of inseminations needed to achieve fertilization. Optimally, the mare’s breeding records should be examined or she should be monitored through one or two estrous cycles prior to breeding to establish the dynamics of her cycle and the size of the follicle that she typically ovulates.

Artificial insemination with fresh-cooled semen can be performed either in-house or on your farm. If your mare is to be inseminated with frozen semen, we require you to board her at our facility for intensive management of her cycle. Ultrasound examinations are performed as frequently as necessary (up to four times daily) to ensure accurate synchrony of ovulation and insemination. Once bred, we recommend ultrasound examinations at day 14–15 (to visualize the embryonic vesicle), day 25 (to monitor for heart beat), and day 35–40 to ensure normal development of the embryo. We are available for consultation throughout your mare’s pregnancy, answering your questions concerning nutrition, vaccinations, and pre-partum expectations.


Mare/Foal Exam

After delivery, a mare/foal exam within the first 24–48 hours is essential to ensure the health of your mare and new addition. Newborns require a thorough examination with particular attention to their limbs, heart, lungs, umbilical stump, and palate. The presence of a ruptured bladder, umbilical herniation, or a patent urachus may require immediate surgical intervention and should be closely monitored.

Your newborn may also require vitamin/mineral supplementation, passive transfer (IgG) testing, and an enema depending on the nutritional status and vaccination history of your mare. Conformation evaluation is crucial, as many orthopedic defects can be remedied or improved by addressing the problem immediately.

Your mare should be evaluated for trauma sustained during delivery. Examination of the placenta is necessary to ensure the membranes were passed in entirety. Retention of the placenta beyond four hours may be life threatening and needs immediate attention.
