Embryo transfer in the equine industry has been primarily used to obtain offspring from mares with restricted reproductive potential (mares with undiagnosed subfertility, uterine disease, or simply older mares) or from performance mares that must remain nonpregnant to continue to train and compete.

9 mar 2024 · Embryo transfer in cattle involves several key steps: synchronizing the donor and recipient cows’ estrous cycles, collecting embryos from the donor cow post-fertilization, evaluating and storing viable embryos, and finally, implanting the embryos into the synchronized recipient cows.
11 gru 2015 · The Difference Between Embryo Transfer and ICSI. With embryo transfer, conception (fertilization) is taking place in the donor mare. This is accomplished through normal means of insemination or natural service.
Since 1978, the current preferred and most common method to transfer cattle embryos into synchronized recipients is via nonsurgical techniques. The embryo is loaded into a small plastic straw (0.25 mL) fitted into a specialized (Cassou-type) pipette (ie, artificial insemination gun).
1 cze 2020 · This review will focus on embryo collection and transfer, cooled-shipped embryos, frozen and vitrified embryos, vitrified oocytes, oocyte collection and transfer, intracytoplasmic sperm injection (ICSI), and sexed semen.
In both large animal species, non-surgical embryo recovery and transfer are well-established techniques. However, success rates after superovulation and cryopreservation of embryos in horses are still lagging behind those of cattle, and more research is needed to address these areas.
In farm animal embryo transfer, transferable embryos are embryos deemed of acceptable quality for transfer into recipient animals as fresh embryos or to be cryopreserved for future use. In 2018, in cattle, the number of transferable in vivo-derived (IVD) embryos produced in the world was ~470,000—less than half of transferable embryos ...
