Costs/worth of embryo transfer

[back_in_the_saddle]

Ideally, you want to use a mare that ovulates on the same day or the day after your mare. Anything else and you increase your risk by a lot.

I used a facility that has a 5 day window (total) around the donor mares ovulation date and it did not work. My vet was not happy when he found that out. I went with them because they were more convenient than the one he normally uses who has a much larger receipant herd and only uses mares who ovulate the same day or the day after. So lesson learned. Ask what their window is for the receipant mare. I won’t go convenient again. I’ll plan to ship hte mare back home next time.

How much do your odds drop by freezing the embryo and waiting until you have the perfect recipient mare? Or does the potential better timing make up for the potential damage that it seems like freezing could do?[/QUOTE]

I was told by the one clinic here that freezes them that if you can get an embryo, there is a 30%-40% chance for pregnancy from frozen embryos.
