I am taking a Equine Production System class at Oregon State University. My professor mentioned that you could collect a embyro for ET every 16-18 days! How is this possible?? He has tried to explain to me, but for some reason, what he is saying isn't making sense! Chart wise, how would you represent this? Thanks! -Rachel

Several time factors must be taken into consideration:
Embryos are flushed at about 7 or 8 days post-ovulation.
The Corpus Luteum will be present and active at the time of flushing and will respond to the use of Prostaglandin.
The mare will (should!) re-enter estrus in about 3 days after the Prostaglandin use.
The mare will (again should!) ovulate in approxomately 5 days after entering estrus.
Ovulation to flushing and PGF2a use:
Time to entering estrus:
Estrus to ovulation:
This would be, on the average, an absolute minimum, so your Prof's 16-18 days is right on the money!
Hope this explains it for you!
