This year, we went into calving season with a lot of stockpiled grass. We want to use tubs or liquid feed along with the grass, but we keep a couple of donkeys in the same pasture to discourage dogs and coyotes from harassing the cattle. Is it safe for the donkeys to have access to those products?
Most lick tubs and liquid feeds contain some urea, which rumen microbes use to make protein. I do not know of any of these that are labeled for use with donkeys. Urea can be toxic to simple-stomached animals. I would not advise this unless you can figure out a system that prevents the donkeys from consuming these products.
