I have fed it in the mash form at about 30-40% moisture. The reason I feed it in this form is because I can buy it considerably cheaper this way than if it has to be dried down more. It is delivered to the farm in large trucks that carry 25 ton per load. I just have it dumped on the ground and I feed it with a front end loader. Some is dumped into troughs and some is put in hay feeders, and some is dumped on the ground. I find that the cows will eat virtually every bit of this they can get. They almost stampede when they see the tractor coming.
For many years, we fed it as stillage, which is the liquid form of the product. It was stored in a 6000 gallon tank with a pump on it. It was pumped into troughs and fed year round. It cost me 1 cent per gallon delivered to my farm which was a 20 mile haul. The stillage allowed me to triple the cows I could run on my pastures, and we had over 300 cows on the same pastures that now carry 100 cows. It was great for AI breeding as the cows would come up to the yard every morning and night when I filled the troughs and I would just sort off the cows in heat when they were standing in the pen. I got the stillage from a distillery but it eventually closed. This facility is now an ethanol plant and their price structure is much higher, but I only feed it when we have poor quality feed or have had a hard winter.
Another benefit for feeding these products is it allows you to keep highly productive old cows in the herd for an extra two or three years.... or even more.
