Strange question for anyone....I have a mare that has been confirmed and is obviously prgnant...300 days gestation..that is showing some signs of heat...is not receptive to the stud but is not striking or such. Will not turn hindquarters towards him..but does raise the tail and "wink"-a very slight discharge...of "normal" color. Can prgnant mares have "false" heats through their prgnancy??????

Yes they can. I don't remember the exact % though. Jos can tell you. :-)
I have a mare that 2 years ago showed every month even through the winter during her entire pregnancy.
She had never done it before and has not done it since.

I have 2 mares that both showed false heats midway though their pregnancies. They showed in November and December, then nothing until May. One of the mares was showing false heat May 12, her next 3 week cycle was the beginning of June, She had some udder developement, but on May 30 (just before 3 weeks after false heat) udder swelled quite a bit, but then shrunk back down to where it was around May 28. I asked around and it seems to be general concensus that it is caused by hormone spikes during pregnancy. Jos or someone else might be able to give you more info, but it sounds faily normal to me (but I am no expert). I am very interested to see if Bucky foals on or close to June 23, because that will be her next 3 week mark.

As the average range of normal gestation is anywhere between 320 and 370 days in the equine, hoping that you will be able to pinpoint the breeding based on three-week increments is not viable. Sorry to disappoint.

Estrus during pregnancy is caused by feto-placental hormone secretion. The same thing causes some mares to behave in a stallion-like manner (but a different hormone - testosterone).

Udder enlargement during mid-pregnancy can be caused by placentitis, and the mare should be evaluated in the event that it is seen.

Around 10% of mares will show estrus throughout or at some stage of pregnancy.
