I went ahead and decided to switch Jessie from the fescue we've been feeding to a timothy/alfalfa mix (per vet orders). It's got a pretty decent amount of alfalfa in it, too.....I'm not sure how quickly I can wean her.....I gave her 50/50 tonight; do you think that's ok? How slowly should I transition her? We are guessing she's got about one more month left before she foals, so.... And what are the chances of her having any actual problems from the fescue? I've heard different things, but never a true "story" until the feed store guy told me about a mare he didn't know was pregnant when they bought her and her placenta was so thick the baby couldn't get out. Does it really do that? Does ALL fescue hay have the mold/fungus that causes that? And is it just on hay? We plant fescue grass in our pasture, and it's super lush this year...will it be ok for her to start having that? We usually start letting them graze in April.... And can she go back on the fescue hay after the baby is born? Thanks!
