Embryo transfer and related technologies in sheep reproduction

Embryo transfer and related technologies in sheep reproduction.

This paper reviews the status of embryo transfer and the major technologies applied to preimplantation of embryos in sheep. Embryo production from superovulated ewes is hindered by an unpredictable response to hormonal treatment. Progress in this area should be expected by an appropriated control of follicular development with gonadotropin-releasing hormone (GnRH) agonist or antagonist prior to...

Equine assisted reproduction and embryo technologies

Assisted reproductive techniques in the horse have been only recently become available compared to other domestic species, in particular ruminants. The scarce availability of abattoir ovaries and the lack of interest from horse breeders and breed associations, and the anatomical and physiological differences have been the main reasons for this delay. Progressively though, the technology of oocy...

In vitro technologies related to pig embryo transfer.

Embryo transfer in swine (ETS) has been used for commercial and breeding application only to a limited extent. However this technique is an essential prerequisite for the application of new reproductive techniques in pigs. This paper will give an overview on steps of pig embryo transfer including selection and stimulation of donor sows, recovery of embryos, embryo handling and the transfer of r...

Embryo Transfer in Sheep and Goats

I-18: Techniques and Technologies for Embryo Transfer: Does It Really Matter.

The learning objectives of this presentation are to understand the dynamics involved in the process of ET, evaluate the evidence for/against common practices and techniques and develop a standardized ET process in view of supporting evidence. Gametes and embryos are handled with extreme care at every step of the Laboratory process. ET is the least sophisticated step of the in vitro Fertilizatio...
