I usually feed wet gluton. It is inexpensive where I'm at, and a fairly good feed. In the winter, I can keep it well over 2 weeks before I notice any mold growing on it, and in the summer if I keep it tarped it adds quite a few days to it's shelf life. Last year I fed old cows hay, stover, and #4 of gluten per day, and they did well. It is high in phos, which is expensive to add in to the mineral, so that also helped. You'll want to start them S L O W on it, or they will have the poop's, it must be kinda rich for their system, especially the calves. But for feeding out or finishing gluten or distillers is great. If the guys get a good deal around here they usually buy a bunch and bag it. It averages $23 a ton. Seen it anywhere from $18 to $38. I think it stinks when the truck drops it off, and it stinks coming out the back end of the cow.
