Corn silage harvest and storage and feeding is very very capital intensive, and one reason small dairies have struggled financially. If small diaries can not afford silage then beef cows certainly can not.
Medium diaries have gone to custom harvested corn silage stored in a covered pile. Better, so you can afford the TMR and the tracked skid steer.
The best way to approach corn fodder for beef depends a lot on alternatives and weather. Cheap corn and frozen ground gives strip grazing the nod - - expensive corn and mud gives selling beef cows to some one with fescue the nod.
