Equine Reproduction Centers, Equine Semen Freezing and Frozen Semen Storage, Embryo Transfer

Located in the horse community of Murrieta in Riverside County California, exit west off the I-15 freeway at Clinton Keith Road, just a short drive from Los Angeles, San Diego or Orange Counties.

We are surrounded by wide open spaces and the tranquil Santa Rosa Plateau. Our unique geographic location welcomes you to our spectacular facility for first class breeding and foaling services. We also offer some Mobile Semen Freezing Services, we come to you !!!

At Equine Reproduction Centers we offer a full range of breeding services including Stallion Semen Collection using a phantom mare, we also offer phantom training for your stallion if he has not been collected using a phantom before, Stallions not collected at one of our facilities before will need to complete a Breeding Soundness Examination to evaluate semen, and test extenders for shipping. We recommend clean out and test evaluation collections at the beginning and sometimes during the season, we can then coordinate the shipping of semen from your chosen stallion.

We operate an on site lab for semen evaluation using a computer semen evaluation system including live microscope images to ensure optimum breeding results before we inseminate or ship. For the semen we ship out we include a complete report of your Stallions Motility at the time of collection for the receiving Breeding Manager or Veterinarian, this information can also be charted onto a spreadsheet where the reproductive performance history of Stallion can be kept, this is a great marketing tool for any Stallion owner.

Artificial Insemination is available for your Mare using fresh, cooled or frozen shipped in or store at our facility semen, our Mare Services include a Mare breeding soundness exam, teasing and ultrasounds. Over the years we credit our high success rate with insemination down to our knowledge using teasing and ultra sounding to find the optimum time period to inseminate. We offer services to all horse owners, not just clients breeding to the stallions we stand.

We are open for service any time, 7 days a week, and can also provide in house horse transport services or airport pick up of shipped semen if needed, we are conveniently located close to Ontario, CA (ONT) and San Diego (SAN) airports.

We offer Embryo Transfer (ET) an established reproductive technology that involves the collection of an embryo (or embryos) from a donor female. The embryo (or embryos) is transferred into a recipient or surrogate mare where a pregnancy can be established and maintained, resulting in the birth of live offspring. We can help in the location of surrogate mares if needed, and as mentioned above we operate an on site lab for semen and fertility evaluation to ensure optimum breeding results. Our experienced staff and attention to detail insure our great success rates with ET.

A more convenient way for Stallion owners to offer breading is to have semen frozen and stored. Semen straws are frozen and stored in Liquid Nitrogen (LN2) tanks. The semen is then ready to use or ship the exact moment a mare is ready to breed without the rush of last minute collections, a real benefit to horses during show season. In the event of a Stallion's death or injury, frozen semen would then be available to carry on bloodlines.

Our services include Stallion Collection, Freeze evaluations, Semen Freezing and Storage and Mare insemination with frozen semen. In addition to just storing frozen semen we offer Frozen Semen Processing and Shipping. The owner of frozen semen stored with us would simply notify us that a request has been made, we can then take care of processing the frozen semen for shipping in a Dry Vapor Shipper and sending it to the Mare owner. We also offer storage for frozen semen transferred from or collected at other locations and facilities, and provide Liquid Nitrogen tank management. Stallion owners able to collect their own stallions maybe able to bring cooled semen to us for freezing, conditions apply so please check with us for details.

Our Frozen semen storage tanks are closely monitored to maintain Liquid Nitrogen levels, tanks are charted and maintained by our own staff, extra tanks and a supply of Liquid Nitrogen is kept on site in case a tank transfer is needed.

Our barn includes a larger foaling stall with 32' x 32' x 16 wide L shaped outside corral.

Our stalls provide a safe & comfortable environment for your mare during foaling, our skilled foaling attendants also monitor our camera system providing 24 hour a day security & care for your horse to ensure the safest foaling possible.

Safe pastures or stalls are provided for mares until they are ready to foal, then the mare is moved to a large foaling stall with cameras, this way we can monitor the foaling process without having to disturb the mare during this vital time. The mares halter is equipped with a foal alert system that also sends out a page if she lies down to give birth, be assured that we are watching your Mare 24/7 and together with the cameras system we are able to watch her every move in case any assistance is needed and provide whatever care is necessary.

We can give care during and once the foal is born, including proper positioning of the foal, monitoring the birth, we also disinfect the umbilical cord, monitor the placenta and give support to the foal including enema's as needed, the foal is monitored for its ability to stand, suckle, urinate, and defecate. All foals born our facility receive a Vet Check by a Licensed Veterinarian and each foal is given the appropriate vaccines as required.

Foaling Process

Each stall has interior access and an exterior door leading to individual turnout.

With owner’s consent, each mare is offered daily turnout until they are ready to foal. We feel exercise for the expectant mare is very important to help prevent edema (swelling in the limbs) and prepare for proper positioning of the foal, as well as a healthy state of mind. We offer individual attention regarding feeding and special needs for your mare, whether it be feed supplements, medications or an injury or lameness that needs tending to.

Mares are observed closely for body & attitude changes, and we keep detailed notes on her progress & habits, so you may use this information for future foalings.

24 hour discreet video monitoring is provided, so we are able to monitor your mare without disturbing her.

Attended delivery by experienced professionals.

Umbilical cord care (navel dip immediately after birth).

On-call veterinary assistance is available if required.

After each foaling, all of the following must have taken place before we consider it a successful foaling: The foal must be able to stand, nurse on it’s own and have passed it’s meconium. The mare must have successfully passed the placenta and be up on her feet & comfortable with all contractions ceased.

After Foaling Follow-Up

Mare and/or foal veterinary exam..

Umbilical cord care (repeated dips over the next several days).

Daily handling & imprinting of the foal.

Rebreeding Options

Should you choose to rebreed you mare via shipped semen, you are welcome to leave her at our facility until she is rebred.
Stringent communication is maintained between our facility, the stallion owner and mare owner to allow for a successful rebreeding at a reasonable cost to the mare owner.

Current year, or recent (within the last 6 months) negative Coggins test.

Vaccination record.

Deworming record.

When to Bring Your Mare

Ideally, it is recommended mares arrive about 30 days prior to foaling. This allows your mare to get acclimated to her new surroundings and to produce antibodies against the microorganisms from the new environment, and subsequently, to pass these to the foal in the colostrum.

Upon a successful delivery, your mare & foal should be able to travel home within a few days of birth.

We offer foal imprinting & daily foal handling in a low stress environment where mare & foal are turned out in pasture, and we also have a pasture for the weanlings where the young horses can play together.

Please email or give us a call for more information on how our we can take the stress out of breeding for you and your horse.

We always have on site equine transportation on standby and the "San Luis Rey Equine Hospital" in Bonsall, California, is available for 24hr emergency care if needed.
