Abstract: Considerable advances have been made in the last 25 yr in sheep and goat embryo production and transfer technology. This presentation covers the procedures used to overcome the variability of ovarian response after treatment with exogeneous gonadotropins, the asynchrony of ovulations, failure of fertilization in females showing a high ovulatory response, and the side-effects of repeated treatments (surgical trauma, gonadotropins and their antibodies). In the ewe, prior antigonadotrophic pretreatment results in a significant gain in ovulation rate due to the elimination of nonresponses and in a two-fold increase in embryo yield. A better comprehension of the relationships between oocyte quality and follicular characteristics after superovulation can be gained using in vitro techniques. This knowledge will subsequently be used for the optimization of embryo production needed for the genetic improvement of livestock and the development of new biotechnologies. |
