We fed it dry for the same reason it expands after they drink, giving them a fuller look. We also use it when holding cattle, just add fat and protein to maintain a fresh look. Depending on the calf it might be 50/50 grain and beet pulp, on calves that needed to be slowed way down it was more like, hay and beet pulp for a few weeks along with the fat and protein supplements.
We have a mill that has a beet pulp mix called EZ-Fill, calves eat it dry, and seem to really like it.
