Lots more hay, especially if she stays out. Horses burn energy just keeping warm so she'll need more out than in. I'd get her rugged up and fed twice as much hay + chaff/bran/pulp in the evenings and she should start putting some weight on. If you're working her then she'll need more energy food, but start with this (or you'll end up with just a fizzy, thin horse). The key though is roughage - to replace the grass that she would have been munching on for 18 hours of the day during the summer. Plus I would give her a wormer.
