I don't think you could just feed it to them as is. The bees bring back pollen a few granules at a time and mix it with nectar and other secretions to make "bee bread" that they subsist on. That is what you see in the frames.
You can buy pollen patties and there are recipies to make your own pollen patties (and pollen substitutes). You might incorporate some honey and maybe a couple of other ingredients to come up with something similar to the bee bread that they make for themselves.
