The biotechnologies search the reproductive efficiency of the bovine herds. Of these the most used with success are the artificial insemination (IA) and embryo transfer (TE). Other biotechniques such as the in vitro embryo production (PIVE) and cloning, also contribute for accelerating the genetic improvement, because they include the use of superior animals. Some biotechnologies used commercially in dairy and beef herds have limitations, among them the PIVE, which suffer influence of several factors, like the oocyte recovery rate and the individual variation in the ovarian response to hormonal treatments, requiring more studies for evaluating the effect of the association between the initiation of the follicular wave and the initiation of the superstimulatory treatment, becoming indispensable the ample knowledge of the reproductive physiology of the bovine female.
