Abstract
Embryo transfer (ET) is a key advancement in reproductive biotechnology, with its success hinging on various factors related to the embryo, recipient, and their intricate interactions. Environmental conditions, for example, heat stress impedes embryonic development and escalates early embryonic loss. It affects the embryo at its pre-attachment stage, but the magnitude of the impact decreases as the embryo develops. In cattle, ET represents a significant financial commitment, mainly due to the costs associated with managing and maintaining recipient animals. Enhancing pregnancy rates in recipients can lead to more efficient embryo utilization, resulting in cost savings by minimizing transfer expenses and the care needed for non-pregnant animals. This review emphasizes the importance of comprehensive management practices, including optimal nutrition, synchronization of the recipient's cycle with the donor's, precise procedural techniques during embryo transfer, and effective post-transfer management, all of which are essential for improving ET outcomes in recipient cattle. Moreover, strategic handling, proper nutrition, and health monitoring, directly contribute to enhanced outcomes.
