Hi Jos (or anyone else who can read this thing. I purchased a mare who the vet said was at 20 days in foal (a miniature). According to that, day 325 would be Feb 23rd. She is already exhibiting signs of foaling sooner than that, and the previous owner sent me a copy of her Ultrasound. They looked over it again, and said that maybe it was closer to a 30 -40 day foal.....can you give me your opinion by looking at this? I read the article on Early Embryonic Death and saw the differences in embryos by date, but I couldn't figure out where this fit into that schedule. Any help or advice will be greatly appreciated. http://i267.photobucket.com/albums/ii281/kdgilger/katelan.jpg Thanks in advance Diana
If it helps, here is what previous owner said about the us "Also to get perspective on the shot. He goes in vaginally with a small animal probe. So you are not getting the top view that you might would see with the anal entry. It is more of a side/top of the uterus.
I think that in second look of this that it might be closer to a 40 but certainly not a 60 day. I had one ultrasounded that was 60 days and you could almost make out a horse shape. I am seeing the beginnings of that here but not quite to that extent."
Without being able to scroll around with the probe, with the view that is given, it's really impossible to determine what stage of pregnancy one is looking at.
If the difference is 20 days or 30-40 days though, the difference is academic, as the number of days difference (10-20 days) is only a small part of the range of gestational duration - even for a miniature.
Thanks JOS, I think what the previous owner was saying was that she could start to make out a horsey shape at around day 60. And I see from the article on EED, that it is indeed possible at that stage. I know there is no "due date " in mares (I have experienced that! LOL) But, I was just trying to figure out if it was closer to 20 days or closer to 40 days, as I was planning a trip out of town end of Jan, and if she was 40 days when the US was done, I don't want to chance leaving her. If she was only 20, then i'd probably go and not worry about it. She's showing all the signs of being ready (except for the udder) so, i'm a little leary, and just trying to gather information. Thanks for all your help.
