Reservation of a recipient mare

When your donor mare is not inseminated by the team of K.I.Hof Ter Leeuwe you have to make a reservation for a recipient mare. This is why it is extremely important that you know the exact time of ovulation of your donor mare and you should reserve a recipient mare that same day.

K.I Hof Ter Leeuwe is an European recognized center for embryo production. This implies that every mare on K.I. Hof Ter Leeuwe that comes for embryo production should be tested every 90 days with negative results on Equine Infectious Anemia (EIA) and Contagious Equine Metritis (CEM).

When a mare is inseminated and / or flushed for embryo transfer by the team of K.I. Hof Ter Leeuwe, we will always perform these tests. If the mare is not flushed by us and you only deliver the embryo, we may only accept this embryo if you have had these tests done by your veterinarian and if you can provide us with the necessary lab results.

A) The embryo flush will be performed by the team of K.I. Hof Ter Leeuwe

  • As soon as you know the exact time of ovulation, you will contact us to make a reservation for a recipient mare.
  • An exact date and time for the embryo flush is planned. All embryo transfers are performed between 9h and 13h.
  • You register that day 10 minutes in advance, and provide us with the invoicing information and the original passport of the donor mare.
  • The embryo flush takes 15 to 30 min.
  • Afterwards your donor mare is always injected with prostaglandins.

B) The embryo flush will be done by your own veterinarian

  • The donor mare has been tested with negative results on EIA and CEM.
  • You provide us with lab results that are not older than 90 days.
  • You contact K.I.Hof Ter Leeuwe the day of ovulation to reserve a recipient mare. We will then determine the optimal time of embryo flushing.
  • Once the embryo flush is finished, you inform us about the result.
  • Embryos should arrive at K.I. Hof Ter Leeuwe no later than 13h, together with the necessary transport document.

C) You cannot reserve a recipient mare in time but still want the embryo transplanted by K.I. Hof Ter Leeuwe

If you cannot reserve a recipient mare in time, so we cannot provide a suitable recipient mare. Then you can opt to freeze the embryo. Depending on the size of the embryo, the most suitable method for cryopreservation will be chosen. The embryo is then thawed at a later time and transplanted to a surrogate mother, or you can provide yourself a suitable mare that can act as recipient mare. By freezing the embryo, the pregnancy rate can decrease to 10%. However, due to our years of experience and knowledge in this area, you can still expect a pregnancy rate of 70%.
