I have poured rum stillage that we aren't using as backset on round bales set on their end before feeding them. However, a lot of the stillage is not absorbed and runs right through the bale onto the ground. I don't know if I am gaining enough nutrients to make it worth the effort. I am currently dumping stillage onto our composting manure pile which will be spread on the pasture later. I have considered spreading it directly on pastures using a tank with a pipe boom with holes drilled in it every few inches to distribute the stillage evenly on the ground. I am not finding any information about the analysis of brandy stillage. There would have to be enough useful nutrients in the stillage to off set the need to apply lime to balance the PH.
