Have you guys had any problems with cattle eating protein that you've put out for deer, whether it be from a feeder or range cubes or even in a trough? We are going to start feeding protein next month, and I know our landowner is going to put a few (10-20) cattle on our place. We don't have pens around our feeders, so I don't want to waste money on protein if the bovines are just going to gobble it up.
