General Information: 
  • Donors:
    • Should be at least 50 days post calving and cycling before entering an embryo program.
    • Do not vaccinate within 30 days of flushing.
    • Semen for a flush program should be of the highest quality and stored / handled properly to maintain quality.
    • Be on a positive plane of nutrition without being over conditioned.
    • Have access to a good trace mineral program.
    • If the donor is a heifer, she should be well grown out and cycling, without being over conditioned.
  • Recips:
    • Ideal recipients are 2 – 6 years old and have no history of infertility.
    • Be in good condition and on a good plane of nutrition.
    • Have access to a good trace mineral program.
    • Vaccinate recipients at least 30 days prior to use.
    • Be sure that recipients are large enough if the birth weights of the embryo calves are a concern.
    • Embryos are transferred to recipients 7 days after observed in standing heat.
    • Embryos can be transferred to recipients based off of natural heats or synchronized heats, both with good results.
  • Synchronization:
    • Consult with us before starting any synchronization to avoid any scheduling conflicts / Sundays / Holidays.
    • Recipients should be at least 50 days post calving before synchronizing
    • Do not vaccinate recipients during the synchronization process.
    • Donors and recipients can be synchronized together to allow fresh transfer using CIDRS.
  • Nutrition:
    • The most important factor for donor and recipients is adequate energy. Ideally this will come from a fiber based source (hay or pasture). Concentrates can be used to supplement energy, but excessive amounts of concentrates may be detrimental to embryo production.
    • Trace minerals are also important to bovine fertility. Donors and recipients should have a good trace mineral product available to them at all times. If they have not been on a good product or there are concerns with imbalances in the ration, then we recommend that a chelated trace mineral product be used. Chelation will improve absorption and can help a donor catch up her trace mineral status quicker.
  • Scheduling:
    • Setting up a donor will take about 21 days from the time of her marker heat to the day of her flush.
    • Donors can be set up at home and hauled to us on the day of the flush, or we can board your donor and manage the superovulation process.
    • If using natural heats for recipients, let us know as soon as possible, so we can schedule the transfer 7 days later.
    • If you are planning to synchronize a large group of recipients, let us know in advance so we can avoid any scheduling conflicts.
    • We can perform transfers at our facility or on the farm. For small groups of recipients or individual transfers we prefer that they be hauled to us on the day of transfer. After transfers are completed, the recipients can be hauled home on the same day. Hauling does not seem to affect pregnancy rates.
