How to feed shredded beet pulp

I have feed shredded beet pulp to my horses in the past. I would usually soak it for a couple of hours. You can see when it absorbs the water and turns it to a softer more palatable mix. I think 12 hours would be overkil. For lack of time, I have heard of people mixing it and leaving set until the next days feeding. I do not like to do that in the summer time. I feed the beet pulp pellets now because they are easier and they are a dollar cheaper. I never feed beet pulp to my goats but it would probably would put weight on them. You can also buy whole flax seed by the 50lb bag and grind it up in a small coffee grinder. I just fill the grinder up with a couple ounces. Its a great source of oil for them. I really notice a differance in coat and skin. I feed my goats a purina product called Noble goat. I give them a little every day plus some alfafa pellets. They also have pasture during the day and then I let them pick in our woods. If they had their choice, they would rather eat tree leaves from low hanging branches.
