Okay, I know the gestation of a horse, but I am wondering how it is determined...first breeding date? last breeding date? somewhere in between?
If a mare bred from April 14th every other day through April 28th (extremely long cycle, vet was surprised she took) what would be her "due date?"

Here is the link to the gestational table on this site. Use the last date bred.

You can go by last date bred or date of ovulation - it really doesn't make much difference, as:

There is no such thing as a due date in the mare!!!


The average gestational period for a mare is anywhere between 320 and 370 days, so as you can see, a day or two difference between last breeding date and ovulation is really not going to be significant!

To reinforce this, take a look at the article on this site that asks Is My Mare Overdue?.

Umm Jos, I feel that your statement is too vague can you be just a wee bit more clear about due dates? LOL Just teasing Jos, you are THE BEST in my book I mean that! Just giving you a bit of a tickle....giggle.

Here's how I do things and it might not be right, but once my mare has her last covering I count the days on her monthly chart throughout the 11 months. today my 2 mares are 288 and 282 days respectively. I keep a diary of changes and attitudes from 280 days onward. The mare at 282 days went 331 with her first foal, a filly and 334 days last year with a colt. So I'm usually looking around the same time frame with her. At 300 days everything is looked at very closely and cameras go up around 315 days. The mare at 288 days is a maiden and so don't have a clue to when she will go. All I can do is watch and note what's happening. The diary is great for noting all habits and what's going on right before they foal.

so basically begin watching closely at 320 and wait!
