Fatores ligados à doadora que influenciam na produção de embriões in vitro (PIVE)

Productivity of livestock cattle, either beef or milk, has been expanded greatly through the improving of reproductive biotechnologies. Among these, in vitro production (EIVP) of embryos have been used in order to generate a larger number of offspring per female, extending the life cycle of them. However, despite the greater advances in most recent years, this biotech still has major limitations, because many factors may interfere on the final results, making feasible or not their implementation on a commercial level. The aim of this review is highlight some sources of variation for in vitro production of embryos in cattle.
