General Tummy problems

So one of my piggies just went through a series of meds for a possible parasite in her tummy & during that time I was advised not to feed vegetable, & do vitamin c in a dropper instead. Well she's doing better now, & I was cleared to give her veggies. But I've been noticing wet poop again. So veggies can you guys suggest for a piggy with a sensitive tummy?
