Reproduction Mare & Stallions

Stallion Reproduction

Our facility features a safe, enclosed breeding shed with a breeding phantom for stallion collection and we stock multiple types and sizes of artificial vaginas. Over the years we’ve been able to accommodate most stallions from Welsh Ponies to large Warmbloods. Chemical ejaculation is also used for stallions that are unable to mount. Semen is carefully measured and examined using our densimeter and microscope. We utilize an iSperm to video and analyze all incoming and outgoing semen samples. Our microscope is fitted with a digitally controlled heated stage to assure constant temperature control. We stock a complete line of semen extenders. Stallions that are being evaluated for cooled semen transport are extended in a wide variety of extenders and semen is analyzed at 24 and 48 hours to assess viability. CGES is a known shipper and is approved to ship via commercial airlines. We can collect semen from your stallion and ship it anywhere in North America.

We also offer semen freezing for stallion owners that wish to store semen indefinitely. The majority of registries now permit the use of frozen semen. Frozen semen has many advantages; a stallion can be collected and semen frozen during the off season and not interrupt his competition schedule, frozen semen preserves the stallions genetic material for use at a later date in the event that a stallion becomes infertile or dies and frozen semen stored on site can be used when the mare is ready, not when the Fed Ex truck arrives.

The semen freezing process is similar to semen collection for artificial insemination. One or more collections are done to “clean-out” his reproductive tract and eliminate the old sperm stored in the reproductive tract. A test freeze is done to determine the suitability for freezing. Special preprinted straws identified with the stallions name, registration number, date and location are used to freeze the semen. After the semen has completed the freezing process, it is then immersed and maintained in liquid nitrogen in special cryogenic containers. Semen can be stored here at CGES for a monthly storage fee or in the owners’ liquid nitrogen container.

Stallions can be evaluated using a combination of history, physical examination, ultrasound of the testes and accessory sex glands, semen collection and evaluation, hormone analysis, culture and sensitivity, serology and urogenital endoscopy. Breeding soundness examinations can be done as a part of the prepurchase examination.

Breeding stallions have the option to stay at the CGES facility. We can train novice stallions to the phantom and can manage sub-fertile stallions. Stallions are housed in large individual stalls with private turnout in one acre double-fenced paddocks.

Mare Reproduction

Today mares can be bred to nearly any stallion in the world using artificial insemination. Mares can be bred using fresh semen collected from your stallion or with transported cooled semen shipped via overnight delivery or via frozen semen from anywhere in the world. Timing of the insemination is critical and our management techniques have been honed over many years of experience. Mares can either be brought to our facility for breeding, or we can perform ambulatory breeding services. We offer skilled mare care and many boarding options.

Ultrasound allows us to detect pregnancy as early as 12 days post breeding. We recommend examining most mares at 16 days post breeding to maximize the detection of twin pregnancy, a second exam on day 30 to assess fetal growth and heart beat and a third exam at day 45 to be sure that the pregnancy has passed through the most critical early stages. Twin pregnancies in the mare usually end in a total loss with both feti aborted. Twins detected at an early stage allows us to eliminate one embryo using ultrasound guidance. Nothing is quite as frustrating as getting a mare in foal only to find that she has lost her pregnancy. We monitor mares at high risk for pregnancy loss by transabdominal fetal monitoring, ultrasound placental evaluations, hormone analysis and placentitis treatment.

For the infertile mare we offer diagnostics including ultrasound, uterine culture, uterine cytology, uterine biopsy and hysteroscopy. Uterine cultures and cytology are used to detect uterine infection. Uterine biopsy utilizes a special instrument which takes a small section of uterine lining. The tissue is examined by a pathologist with critical attention to any sign of infection or scar tissue. The biopsy score can be used to direct the reproductive course of the mare. Hysteroscopy utilizes a fiber optic endoscope to enter the uterus and visually examine the entire uterine surface for adhesions, scars, fluid, cysts and tumors.

The majority of mares will conceive with ease when bred to a fertile stallion. We are equipped with the tools and experience to manage the problem mare who suffers with chronic endometritis, post mating endometritis, fluid retention and ovulation failure. We carry a complete line of uterine lavage catheters and our pharmacy is well stocked with the necessary pharmaceuticals to assist your mare.

For mares that cannot carry a foal to full term, mares that are actively competing and cannot take a year off to raise a foal and valuable mares where more than one foal per year is desired embryo transfer may be an option. Embryo transfer involves breeding the donor mare and 7-8 days later flushing the donor mare to collect the embryo. The embryo is then transferred to a surrogate mare which carries the pregnancy and raises the foal. You may furnish your own recipient or utilize a mare from a recipient mare herd.
