Hello everyone, I am new to the board. So please bare with me. I have been around horses for some time,just not my own. I got two fee mares recently to teach the children how to ride. One was a rescue senior and I now have my own Maiden Mare who is in foal. But I dont know how to calculate the foaling date. I was told to count 11 months from the last date bred. Is that true? My mare was bred May 9,11,13,15 2008. So if I counted correctally she should foal around March 19th right? I counted every week up untill 11 months. Or do I expect her to foal April 15? I dont know. Some months have 4 weeks others have 5, so really I have know Idea. I really would appreaciate it if anyone could help me.
If you look at either the article from this site that's linked above, or the gestational duration range that's shown on the front page of the web site, you'll quickly understand the range of foaling, so technically speaking, one can start looking for signs at 300 days, as that is the earliest that one is likely to have a foal survive if born - although it would definitely be a struggle for it - but as you note, anytime from 320 days onwards is in the "normal" range! Note that under 17% of foals are born in the 339-344 range!
Thank you for the help Samantha and Jos. It makes totall sence.
