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.
1 cze 2020 · This review will focus on embryo recovery and transfer, cooled-shipped embryos, embryo freezing, oocyte freezing, oocyte collection and transfer, intracytoplasmic sperm injection (ICSI), and sexed semen. Embryo transfer procedures have been constant for many years and the costs have not changed.
Horse breeders without an adequate number of recipients and veterinarians with modest investment in equipment can collect embryos and prepare them for short storage and transport to a centralized embryo transfer facility.
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.
Total production (transferrable embryos) of IVD and IVP embryos1 in 2022 in cattle, sheep, goats, and horses, by region
1 sty 2014 · The mean number of embryos produced via superovulation has changed little in 40 years, but there have been improvements in synchrony and hormonal protocols. Cryopreservation of in vivo -derived embryos is a reliable procedure, but improvements are needed for biopsied and in vitro -derived embryos.
