Yes I would recommend some cardio for health reasons as well as keeping bodyfat down.
you just have to make sure you're diet in check to compensate for the extra expenditure.
It makes me laugh whhen people say u shouldn't or u won't gain if u do, just look at athletes, rugby players is a good example, they do loads of cardio and they seem to manage it!!
I would recommend HIIT, and crossfit style training to keep lean while bulking.
