There was an article in Profi the other month of a Dutch farmer who was using cow urinals to reduce the amount pee in the slurry , it reduced significantly the emissions , increased the quality of the muck and its value as fertilizer as there was some protein i think in the pee that broke it down and made it gass off and he could i think also sell the pee for some sort of industrial process.
If they're trained to not sh!t and pee when they come into the barn then it could be very helpful for things like milking parlours.
Also if they only use one area of the pen, then they shouldn't be doing it on the bunk line which would make the ground last a lot longer if it isn't cement (and the bunk line much easier to clean up.) Could even eliminate the need for bunk lines to be cement.
If you can't think of ways it could help you obviously haven't cleaned up enough sh!t. The one frozen poo that always gets in the way of the gate opening could eff right off to the poop spot.
