Also, see if you can offer her fresh grass clippings from clean, non-chemical treated grass...this has been recommended to me to help get beneficial bacteria/natural probiotics into my horses' guts after they have been treated with antibiotics.
Probios also comes in paste form and is easier to dose by far than powder...it would be in the horse section of the store, not sure how much you would give by weight, you'd have to wing it on that one.
