I have a 7 yr old  TB mare, still sound for racing, has broken her maiden, still sewn up so she is breeding sound!  She is out of the world reknowned stallion NUMEROUS, maternally she has Majestic Light breeding!  She has awesome bloodlines, you can research her at http://www.pedigreequery.com/ just put in Stanleys Light.  She is a money earner.  She has been off the track for the winter as we do not have racing here in Michigan in the winter.  She was raced as Suffolk Downs,MA.  Her asking price is $4000 firm!  You can not touch a Numerous bred mare for less than that!  If you want a good commercially bred mare for your breeding program.  Look no further!

sewn up?

Before a filly can run their vagina is sewn up so they don't "suck" air in when they run.  She is 7 yrs old and has never had it reopened , so she has never been exposed to a stud or diseases. She is a virgin in that aspect if you may. 

I guess you have never owned, trained, or had a female race horse then.  Learn something new everyday with horses, no matter how long you have been around them we always learn something new.  I never knew that until I got involved with racehorses.  My cousin is a retired jockey and she is the one who got me started in it.  I thought she was kidding when she told me about it.  Now you know.
