Antología de la transferencia de embriones en equinos

Abstract

This document addresses what concerns the embryo transfer technique to be applied in the field; is defined as a procedure by which embryos are collected through uterine lavage, this in a mare that is between six and ten days after ovulation, and that has either been inseminated or has been used natural riding (Torres, 2012); This recovered embryo is transferred into the uterine cavity of the recipient mare; It is worth mentioning that the technique requires prior synchronization between mares (donor-recipient). The guidelines followed in this documentary research were based on the revision of texts and also on documents and research published through platforms such as PubMed; The analysis of the documents was carried out, selecting those that responded to the proposed objectives; The general objective was: Compile the relevant information on the transfer of embryos in equines, tending to favor the percentage of success in obtaining embryos that reach term, in the field; To respond to this, the specific objectives were: To establish the aspects that have influenced the success of embryo transfer, from the beginning of the implementation of this technique; Categorize the various activities that need to be considered, to favor the percentage of success in the transfer of embryos in equines; Propose a sequence of activities, based on the definition of critical points of the process for the transfer of embryos in equines, tending to favor the percentage of success in obtaining embryos that reach term, to be applied in the field. The result was aimed at presenting a proposal for the application of the TE technique to be applied in the field, presented through three moments (before, during and after), in which the activities to be carried out are listed to minimize the critical points detected and favor greater optimal results; thus contributing to the knowledge two relevant elements, on the one hand, the compendium of present knowledge from the beginning of the technique to date on TE in equines; on the other hand, the sequence of activities to apply the technique in the field as a guide that facilitates the process by strengthening the critical points found; likewise, the collection of data arising from the application of the technique is encouraged to promote the publication of research that improves results and minimizes critical points.
