Carneiro, Gustavo Ferrer
Background: The use of Embryo Transfer (ET) presents significant advantages in its application, however some particularities impose certain limitations on its use. Review: The use of ET has expanded in recent years with a focus on Brazil, United States and Argentina. Virtually all Equine Associations support ET, confirming its benefits. With the main objective to maximize the success of equine ET programs, it becomes essential the understanding of main factors affecting reproductive efficiency with differences between regions. Among those factors include reproductive seasonality, donor history, quality of semen or Stallion individuality, selection and management of recipients, treatments for a better synchrony between donor and recipients. It is the responsibility of the technician to clarify Breeders in which situations is best to use this technique. Conclusion: The goal of this work is to discuss particularities and difficulties related to equine ET in the Northeast region of Brazil.
