I have seen people use Strategy during pregnancy. I couldn't give you an estimated idea what to feed her because i'd have to look it up and I'm out of town. I'm sure someone here will be able to answer how much to feed her. As for feeds, it depends where you live. Purina growth or ultium, or life and design mare and foal is good but I'm from indiana hipe this helps you :) Posted via Mobile Device
I wouldn't increase or change anything until you find out FOR SURE that she is bred. Increasing her food if she isn't pregnant is a horrible thing to do. Then she gain's weight, looks even more pregnant and your sitting there waiting for baby to come, and it never does and all your left with is an obese mare.
One of the biggest mistakes people make is increasing feed to bred mares. Unless they are loosing weight there is no need to increase their feed. You will end up with a mare who puts on too much weight and the foal gets too big and she has problems. Just keep feeding her what she is getting no more no less and you should be fine. If she is loosing weight then slowly increase it. On the same note if she is putting on too much weight then cut back a bit and do that with the grain and not the hay.
How far along is she? You should change her diet till the last trimester. Feeding more early on is a waste of money as she doesn't need the extra food/energy/ nutrition.
I HIGHLY recomend FeedXL.com. You input your horses info and what you're feeding, and their site analyzes it and tells you what you're over feeding and can/should cut back on & what is missing or deficient. It's SUPER accurate and Im constantly reevaluating what and how much I feed based on their advice.
That being said for my mare Julep who was 1500 lbs before she was pregnant and is a super easy keeper and is due in 2 weeks if not sooner:
26-28 lbs of Timothy
1/2 a pound Ultium Growth
