Embryo Transfer Procedure
The Embryo Transfer process is a series of steps if undertaken in the correct manner will maximize your investment in embryo transfer. A donor is selected based on genetic merit, treated with superovulation hormones (similar to IVF in humans) and bred to a superior sire.
- Embryos are collected 6 to 8 days after heat, and once collected the embryos can be:
- Sexed – determination of the sex prior to transfer or freezing
- Split to make identical twins
- Frozen for later use or export – both sexed and unsexed embryos
- Transferred to synchronised recipient cattle.
- Average embryo production per donor collected is just over 6.
- Average pregnancy rates from best quality embryos, sexed or unsexed, to well prepared recipients is over 70%
