Re: [RC] 'Easy' mare <rated pg-13> - Dabney Finch

Hey, thanks for that faulously easy to understand explanation!

But in a way my question still stands--the only other mare I've had did come into heat Big Time at her first ride and Suzy Kelly (whom I'm guessing has won more races [often w/ BCs] on her "home-grrown" mares than any other rider in AERC history) just responded to my same question then: "well when you go somewhere where there are lots of gorgeous guys, don't you go into heat?") Hmmm....

So, I'd love to hear some feedback on this: are mares more likely to go into heat at rides? And, if so, is Regumate the answer--or does exposure/experience help? Or what else?

What is a "transitional heat"?  (And if, as I'm guessing, it is when a
mare  is transitioning into new surroundings, doesn't it then happen
also at  rides?)

Transitional heat is the normal occurrence every spring when mares go from winter anestrus (not cycling, or non-fertile cycles if they do cycle) to normal spring and summer cyclic behavior. When the extra light from the lengthening days starts to "turn on" the reproductive hormonal axis, the inactive ovaries go into high gear and produce a whole bunch of little bitty follicles (feels like a bunch of grapes when one palpates the ovary) that in turn produce the hormone estrogen, which is the one that causes heat behavior. These little follicles will tend to come and go for up to a month or more, madly producing estrogen to the point that the mare is often an utter hussy, but they don't go on and mature and ovulate, so there is nothing to shut the system off, so to speak. After this goes on for awhile (can be a month or more, as already stated), one follicle will finally sort out of the pack, go ahead and ovulate, and the remaining tissues will start to produce progesterone. At that point, the mare finally goes out of this hussy behavior and starts to cycle normally.
