Have fed potaoes, onions, carrots, apples, pears, turnips, & sugar beets. All are good feed but will need additional protein. All are high in moisture and will cause the squirts if fed in large amounts. No harm to the animals with the squirts, just high digestibility feed. Have had bloat when hungry steers were turned in on a truckload pile of cull potatoes. Bloat not a problem if cattle have other grass or hay and don't tank up on veggies. If I had a source of veggies, would feed all I could get. Minor chance of choking when attempting to swallow whole apple, pear, beet or turnip.
I'm not aware of any veggie type feeds that are detrimental to cattle. When feeding cull potatoes, the cattle seemed to prefer the rotten ones. Yuck...
Probably others who have fed other things.
Good luck & best wishes.
