What is the longest gestation for normal foal birth? I've seen 325 days listed for premature foals as early birth, but what is the longest?

Some of my mom's own mares have carried as long as 12 -13 months. I foaled out one TB mare who was at 12 months and one week when she finally foaled an nice health baby.

12 months is the usual

The usual gestation is 340 days or approximately 11 months. However some can go 12-13 months and still deliver a normal healthy foal.
