Square are the standard here...although rounds are becoming more and more common. With the current price of hay here...I don't "do" waste! :) I weigh it (they are chubby), and put the hay in metal troughs, additives in rubber tubs. A stylized tractor tire would actually be great for me (one level) b/c my mare "bangs" when she has finished dining.
There is just as much horse sense as ever, but the horses have most of it.
