The only source of protien to supplement the native grasses in winter appears to be high quality alfalfa that is not GMO.
I used to buy urea and mineral together. Put it in a lick tank and let them regulate their own intake. It comes in liquid form (a thick syrup) and the poly tank was set up with wheels that the cows would lick.

The only problem with urea as a protein supplement is that you must feed corn with it to activate it.

Another method mentioned in another thread is to grind corn, extrude it with urea at low temp so the starch doesn't scorch (around 180 degrees). When soy got high 20 years ago this was a preferred method (cheap) to get protein into their diet.
