Effect of Duration of Embryo Holding on Recipient Mares ’ Pregnancy Rate

Equine embryo transfer (ET) is a biotechnological procedure that has become common practice in horse breeding, and the number of foals from ET in commercial operations is increasing steadily. When embryos are collected for direct transfer on farm or preimplantation genetic testing, the embryos are routinely stored at room temperature in holding media before transfer into recipients. However, the interval from embryo recovery to transfer is regarded as a parameter directly related to embryo survival.
