If she's belching liquid it
probably (I'm not a vet though!) means that there's so little room inside now that her stomach gets full very quickly, although it could be that it's too rich for her and is causing indigestion. I know anything like that goes through my dals like a dose of salts! Remember, it's not merely calories she needs, it's calories from higher protein or fats. Personally I'd put a teaspoon of olive oil on her meat rather than feed anything like Hi Life.
