  • Title: [Embryo transfer in the goat--a review].
    Author: Holtz W.
    Journal: Dtsch Tierarztl Wochenschr; 1996; 103(8-9):293-7. PubMed ID: 9011494.
    Abstract:
    The available techniques for the control of the estrous cycle and superovulation in goats are covered. Most commonly the estrous cycle is controlled by means of progestagen pessaries or s.c. implants. To superovulate goats, FSH is more suitable than PMSG. As an alternative, goats may be immunized against inhibin. Premature regression of corpora lutea is a common complication in superovulated goats. Collection and transfer of embryos is usually accomplished via laparotomy. Occasionally endoscopic techniques are utilized. A recently invented technique for transcervical embryo collection is touched upon. Methods of in vitro culture and preservation of embryos resemble those commonly applied in cattle. Satisfactory success rates are achieved with the transfer of frozen-thawed blastocysts. Vitrification of goat embryos is feasible. There are reports on successful splitting and fusion (chimaera formation) of goat embryos and on in vitro fertilization (IVF). The goat may serve as a suitable model for the invention of new approaches in biotechnology in ruminants.
