Frequently Asked Questions

Can another mare be substituted for the original enrollment mare?
No.  Another nomination fee will apply for each subsequent enrolling mare.

How many flushes are included in each nomination fee?

The nomination fee for both the on-site and transported contracts do not limit the number of flushes.  There is no penalty for numerous tries

Can the contract be carried over for the next year?

No.  The nomination is for one season only.

How late in the year will there be recipient mares ready?

The contract dates run from February 1 until December 1 so there will be recipient mares cycling and ready to receive your donor mare’s embryo.

Will you have enough recipient mares?

There are over 500 recipient mares in the herd in all shapes and sizes. We have a team of technicians that are here to make sure we will have a recipient mare ready when your embryo arrives.

Can I request a certain recipient mare or type of mare?

We generally try to match the donor mare’s breed type with a recipient mare of appropriate size.  You can make requests concerning recipients breed, size, etc. but we cannot guarantee to meet those requests.  When selecting a recipient mare for each embryo our first criteria has to be to select for the most likely to result in a pregnancy and live foal.  After that criterion has been met we can see if other requests can be satisfied.

What if my recipient mare loses her pregnancy?

There will be a $2,000 credit put on the account for future embryo transfer work if the mare loses her pregnancy after the initial 30 days pregnancy examination, or if the foal fails to stand and nurse within 24 hours of birth.

How many embryos can a mare produce in 1 year?

That is dependant on the fertility of the mare and the length of the breeding season.  A mare can be flushed an average of every 17 days.  With good fertility an embryo should be produced on the majority of those cycles, so that quite a few pregnancies can result over a period of time.  We’ve had several mares with 6-7 pregnancies in a season, and even more are possible.  Unfortunately not all mares presented are that fertile, especially if they come with a history of reproductive problems.  Repeated breeding can also result in inflammation or infection in some mare requiring some time off between breedings in some instances.  On the other hand super-ovulation can increase the number of embryos recovered from relatively young mares but its use in older mares is often unrewarding.

Who orders the semen?  How will I know when to have it shipped?

We will coordinate breeding and the shipping of semen for donor mares here at EMS.  We ask that you make all stallion arrangements ahead of time, including paying your stud fee.  For frozen semen its best just to have that shipped to EMS ahead of time so that we can have it in storage before its needed.

Why do you recommend that we insure the recipient mare and fetus?

The recipient lease is strictly that, a lease, so that you are responsible for the health of the mare while she is in you possession.  If she should die, not only will you lose the fetus (although you’d receive the $2,000 credit) but you will owe EMS for the purchase price of the recipient ($1,350).

What is the best way to ship my embryos to you?

For the transported embryo, the less time out of the mare, the healthier they are.  Make whatever arrangements you can to reduce the transport time.  We recommend flying the embryos counter to counter, but if that is absolutely impossible and you want to use Fed Ex, you’ll need to schedule the embryo recovery flush as late in the day as possible.  Shipping counter to counter requires the shipper to be pre-approved by the airline as a “known shipper”.  If you do not have this capability, we can arrange for a courier to pick up the embryo and transport it to the airport and have it shipped under our “known shipper” status.

Is it better to send embryos or to have the mare come to EMS?

Pregnancy rate is slightly better for non-shipped embryos (about 5%).   Most mares can be handled well at your facility and the embryos shipped if you have a veterinarian with the expertise to handle the breeding, flushing, and packaging for shipping.  Some mares with breeding problems might be handled better here, but if you are breeding to a stallion whose semen doesn’t ship well it might be best if the mare is near the stallion so that fresh semen can be used.  The decision of whether to bring the mare to EMS or handle it at home may involve the occupation of the mare (are you wanting to keep her in training or showing during this process), availability of air transport (how quickly can the embryo be shipped), the expertise of you veterinarians, and the availability of quality semen.
