Multiple Ovulation Embryo Transfer (MOET), a conventional embryo flush, is the most common procedure used in advanced cattle breeding.
It involves a 5 week superovulation program, resulting in several eggs being released from the donor cow, as opposed to one during a natural heat. The cow is inseminated and embryos are then flushed from the cow's uterus the following week. This involves placing a catheter through the cervix and into the uterus, where a cuff is inflated and fluid is flushed in and out to collect the embryos from each horn.
An average flush would produce 5 embryos, additional advantages of this technique are as follows:-
- Increase the reproductive rate of individuals or groups of animals
- Embryos can be transferred fresh, or frozen in our lab for use later
- Entire procedure can be carried out on farm
- Consider 'banking' embryos in case of future TB breakdown
