Donkeys and Lick Tubs

Question:

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?

Answer:

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.
