Make sure that during the last 3 months she gets some type of a supplement/concentrate. You could give a complete sweet feed or a complete pellet, or even a grass pellet. It doesn't have to be a lot, just as a snack or nutritional supplement. I am just giving Niobe alfalfa pellets mixed with rolled oats as a snack. I used to soak pellets during the last 3 months, but my mares get lots and lots of grass now. You don't want them to be overweight going into the delivery, but underweight can be harmful because of the calories that are lost in delivery and lactation. Make sure she has lots of sunlight, fresh water, a mineral salt lick, and preferably free access to a dry lot where she can go in and out as she pleases. I believe Spring grass is a very important element for a pregnant mare and a healthy foal. If she is not used to grass start her out 5-10 minutes of grazing for several days and work your way up. She could be worked up to 2 hours of grass a day and then you can cut hay and grain way back. I think the most important thing for a mare is not to be stuck in her stall. She needs lots of room to walk around and roll and get sunlight. I really believe space to roam can help position the foal. A deworming schedule is important! I think the most important thing is to be there. From day 300 on start to stay home. After 320 don't leave her if at all possible. If you do leave have someone else stay and watch. I'm very blessed to be a stay-at-home mom and I will miss events because I feel so strongly that I must be there. I will check mine every 2 hours throughout the day and night when they are close. Sometimes I won't leave them. That is where having a camera system and several other methods of observation would rock!
