simple.
With a ruminant you are actually working with bacterial nutrition as well as
conventional mammalian. Hence urea is an excellent feed for rumen bacteria
who can convert it to bacterial protein, which the cow can then use.
Unless you have large numbers of rumen bacteria I suggest you leave urea to
ruminents
