Featured Question

Should I not consider frozen semen if the mare is an ET donor?

Keeping that in mind, the timing for the embryo flush should generally be done at 8 days post ovulation rather than 7 days to make sure that the embryo has migrated to the uterus, thus making it possible to be recovered during the flush.
