The effective scheme to induce poliovulation for transplantation of embryos in goats

In embryo transplantation, there are some subsequent manipulations, of which the induction of polyovulation in donors is one of the most important element. At that, the main problem consists in variability of ovary response to treatment. The ovary reaction to the estrogenic hormones differs depending on changes in the endogenous hormonal pattern which can influence directly the fertilization and embryo development. The suggested scheme can be used to induce the polyovulation in donor goats for embryo transplantation with highly synchronized ovulalation that does not depend on an initial hormonal pattern of the donor. According to the scheme, Krestar implants are being used for 8 days. Folligon must be injected in a dose of 500 U. The fractional injections of Ovagene (7 ml in total, by 1 ml each 12 hours) are conducted starting from the 60 hours before the implants are removed. At fixation of estrus the animals were injected with Chorulon in a dose of 500 U. This scheme both in estral and unestral seasons results in a stable polyovulation with the efficiency of 15.5-17.5 yellow bodies and 74.0-90.5 % output of embryos good for transplantation.
