Hey and other coarse fiber products like beat pulp, take longer to break down in their gut, so it helps to keep them looking full. The microbial break down of the fibers also releases a lot of gas in the stomach which will help to expand his stomach and should give him more depth in the flank. That is probably my biggest flaw for him is he gets a little tight flanked. In these new pics I can see that you will have at least some leg hair to work with. Is this a county show? Is it full fit or blow and show? Either way, continue to work that hair, elbow grease is the best thing you can do for them. About a week before the show I would get some die in him just to cover that faded hair. I think with a good fit job he will look like a totally different steer.
I dont know how competitive the show is, but I think he is a fairly competitive county steer. At a bigger level show, I would think he is about middle of the road. He is a good complete steer, appears to be finished, looks sound, and has adequate thickness to him, but at a bigger show I think you will find several that are just a little more stylish, deeper flanked, with more shape over all. But I think he is a nice steer and looks like you have done a good job raising him, and that is what is most important. Regardless of where you place, congratulations on a job well done and be proud of the effort you have put in.
