Control of Foaling after Embryo Transfer

Abstract

Equine embryo transfer is used globally to obtain an increased number of high-quality foals from mares without interfering with their competitive career. However, there are various factors that can influence the production of a healthy foal, the control of foaling after embryo transfer will be explored throughout this review. Those investigated throughout include the quality, size, and day of recovery of the embryo, the donor mares age and whether she is competing, and the parity and size of the recipient. Intrauterine growth retardation and its effects on the development of the foal are reviewed through between breed transfers, such as thoroughbred in pony. Deepening our understanding of such areas will ultimately produce top foals.
